Nausea is the first indicator that dangerous toxins have appeared in the body, this is how the brain tells us about it. If the body fails to neutralize toxins - on its own or with our help, nausea intensifies and often ends with vomiting - everything harmful is simply ejected out along with the contents of the stomach, and the problem is thus solved. However, toxic substances do not always penetrate from the outside - in some diseases of internal organs and physiological processes they “attack” from the inside. Therefore, it is not always necessary to attribute the manifestation of nausea only to poor quality food. Let's try to find the real reason.
True, there is also a “non-toxic” explanation for unpleasant sensations in the pit of the stomach - these include a disorder of the vestibular apparatus when it is overloaded (motion sickness) and the consequences of a concussion. In the first case, nausea is caused by long car trips, sea motion, swing rides, which affect the vestibular apparatus, in the second case, complex neuro-biochemical reactions are to blame, arising due to a sharp increase in intracranial pressure, swelling and compression of the brain due to with a head injury. In both cases, nausea does not suddenly occur, so you have to manage to make a mistake with the cause.
Both with motion sickness and with a concussion, you need to ensure complete rest, sniff a cotton swab moistened with a solution of ammonia, suck on a Validol tablet or any menthol lozenge. Motion sickness syndrome usually goes away quickly, unless it was caused by serious damage to the auditory or vestibular system (Meniere's disease).
With hypothyroidism - decreased function of the thyroid gland - nausea is regular, mild, but constant, even exhausting. Its manifestations are not related to body position or eating. Once it occurs, unpleasant sensations can last for hours and days on end. At the same time, appetite disappears (although against the background of hypothyroidism it is generally reduced), but chilliness, drowsiness and general apathy appear. I want to lie down and cover my head.
Sometimes, if time permits, it is best to do so. After a couple of hours of rest, nausea may disappear. It is better not to bring yourself to extreme fatigue at all and ensure a reduction in loads as soon as you feel its first signs. And, of course, if you suspect problems with the thyroid gland, you need to take a blood test to check the levels of the hormones TSH, T4, T3, and if the levels are not normal, go to an appointment with an endocrinologist.
Intoxication can also occur during prolonged stress, when a large dose of adrenaline is released into the blood. And this is regarded by the body as a toxic attack.
The main thing is to calm down, then, most likely, the nausea will disappear.
The body is clogged with toxins when there is a breakdown in the functioning of internal organs - primarily the kidneys, liver and intestines, which are responsible for digestion and metabolism. Most often, nausea is characteristic of serious renal dysfunction, which cannot cope with the removal of protein breakdown products and other residual harmful substances. When the intestines are clogged, toxins penetrate through its walls into the blood, and the liver and bile ducts in various diseases are not able to ensure proper metabolism. All this causes a poisoning reaction in the body.
In case of prolonged and frequent nausea not associated with meals, it is necessary to undergo a full examination - an ultrasound of the abdominal cavity and kidneys, urine and blood tests (general and biochemical) to establish the primary suspected area of the lesion. And then narrow the problem down to a specific diagnosis. With internal diseases, it can be difficult to relieve nausea, although it practically does not turn into vomiting.
Prolonged, uncontrollable nausea can signal the presence of a malignant neoplasm. The body reacts to cancer cells as if it were a foreigner poisoning the blood and seeks to reject it. It's a pity that cancer cannot be spat out or thrown up...
At the slightest suspicion of a “stranger,” it is better not to delay a visit to the doctor, no matter how scary it may be - the unknown is not only more frightening, but also fraught with the danger of delay. After all, the brain warns!
The body also reacts with nausea to the introduction of a bacterial or viral infection, and to the latter - more strongly, since it is potentially more dangerous. But here, along with nausea, fever arises - immune cells turn on their defenses.
Here you only need one thing - to treat the disease by eliminating the infection. There is no need to urgently lower your body temperature; it is like a protective barrier between the body and “strangers.”
Sometimes nausea appears unexpectedly in the form of severe attacks. This could be a reaction to a food product, a smell, or even a specific person. We are most likely talking about an allergy or intolerance to a given product... or a person. In the latter case, the psychological factor is triggered.
The only way out is to eliminate the object of the acute reaction.
Nausea often occurs as a side effect of taking any medication. For example, antibiotics and drugs used in chemotherapy are often responsible for nausea. Another option is an incorrectly calculated amount of the drug, which leads to an overdose.
If you manage to associate attacks of nausea with taking a specific medication, you need to change one drug to another or recalculate the dose. Naturally, it is better to do this with a specialist.
Irregular meals, strict diets and simply prolonged periods of fasting also cause attacks of nausea. The reason is low blood sugar. The brain uses this method to communicate the need to eat when other hunger signals have gone unheeded.
Eating is the first task if you haven’t done it for a long time. Usually in this case, nausea is accompanied by a sucking feeling in the pit of the stomach. Just don’t try to immediately consume sweet foods on an empty stomach, otherwise nausea may even worsen.
Most often, nausea is a symptom of diseases of the digestive system and biliary tract. Such nausea has characteristic symptoms.
How to avoid nausea while eating? People are not always interested in this issue, and the occurrence of a problem should be considered a truly alarming symptom. That is why, if the condition occurs more than twice and is not associated with food poisoning, it is strongly recommended to consult a specialist. What are the main reasons why nausea occurs when eating?
One of the key reasons for the formation of such a phenomenon as nausea is cholecystitis. We are talking about an inflammatory algorithm in the area of the gallbladder or the appearance of stones there. Any of the processes presented can provoke not only the indicated symptom, but also painful symptoms during and after eating. Experts note that precisely with cholecystitis, even at the initial stage of its development, nausea is not the only manifestation.
It is the accompanying symptoms that will help determine the causes with a high degree of accuracy. In particular, cholecystitis provokes bloating, heartburn, and bitterness in the mouth. There is a high probability of developing flatulence and significant pain in the right hypochondrium. Thus, the presented disease is quite easy to identify if you pay attention to the provoking symptoms in time and consult a specialist.
If nausea occurs when eating, this may be direct evidence of the use of certain medications. As is known, the vast majority of medicinal components have side effects that can occur even when using the drug in normal quantities.
Speaking about other reasons that cause nausea, I would like to draw attention to the use of certain medications in large quantities.
In the vast majority of cases, such manifestations are associated with components such as iron preparations, antiviral and anthelmintic drugs. No less rarely, this can apply to antibiotics and anti-inflammatory drugs. In order to avoid or be prepared for these symptoms, especially when eating, it is strongly recommended to consult a specialist.
Next, I would like to draw attention to the fact that nausea occurs due to poisoning. In some cases, if it is minor, symptoms may not occur on their own in the form of vomiting, but may provoke discomfort when eating. Poisoning can occur after eating stale foods or poorly washed fruits and vegetables - which is why experts strongly recommend monitoring your own diet and paying attention to any unusual symptoms in a timely manner.
Nausea is an unconditional symptom indicating the development of gastritis. The fact is that it is inflammatory algorithms that affect the development of nausea during or after eating. Anyone who has experienced gastritis in one way or another knows about this, and therefore it is recommended to take certain precautions. It is necessary to pay attention to the fact that if the causes are gastritis, then this is associated with certain symptoms.
We are talking about a feeling of heaviness in the epigastric region, a feeling of significant distension. In order to cope with gastritis, experts strongly recommend adhering to a certain diet. Moreover, this must be done over a long period of time or even throughout life.
The next factor in the development of such a phenomenon as nausea after or during eating is migraine. You need to pay attention to the following symptoms:
It is by following the presented measures that you will be able to eliminate the occurrence of nausea while eating, as well as severe migraine attacks.
Pyelonephritis is an inflammatory process in the kidney area. This condition can provoke such nausea, which quickly transforms into vomiting. An important differentiating symptom that fully determines the causes should be considered pain in the lumbar region and problematic urination.
Next, you need to pay attention to the likelihood of developing hypertension, which can also be a trigger for symptoms such as nausea. As you know, hypertension is a specific condition in which constantly increased blood pressure readings are identified. In this regard, nausea occurs not only during eating, but also simply in the morning. Hypertension may be accompanied by dizziness, edema and facial hyperemia.
Brain injuries are no less rare causes that cause nausea to occur during or immediately after eating. The fact is that a concussion, bruise or other similar injuries provoke discomfort in the abdominal area, which is characterized by a neurological origin. That is why, when such injuries occur, it is recommended to follow a diet and use certain medicinal components.
One of the initial symptoms of appendicitis is nausea, which will manifest itself not only during meals, but also regardless of the process presented. More typical symptoms of an inflammatory condition of the appendix are vomiting and pain in the abdominal area. In this case, the latter are located first in the upper abdomen, then in the lower right.
The condition in this case will be accompanied by low-grade fever (permanently elevated temperature).
With a heart attack and problems with the heart, nausea is also likely to develop. At the same time, it is accompanied by attacks of vomiting, which do not bring relief to the patient. It is important to note that the symptoms are accompanied by pain in the abdominal area. The development of hiccups, a change in skin color to a paler color, and a feeling of suffocation are likely.
The next problematic condition is meningitis, the formation of which is almost immediately expressed in nausea while eating food. Experts note that such nausea is exclusively neurological in nature. In addition, along with meningitis, other associated symptoms are identified. In particular, we are talking about high temperatures, fear of light and a feeling of strong pressure in the occipital region.

1.Can cancer be prevented?
The occurrence of a disease such as cancer depends on many factors. No person can ensure complete safety for himself. But everyone can significantly reduce the chances of developing a malignant tumor.
2.How does smoking affect the development of cancer?
Absolutely, categorically forbid yourself from smoking. Everyone is already tired of this truth. But quitting smoking reduces the risk of developing all types of cancer. Smoking is associated with 30% of deaths from cancer. In Russia, lung tumors kill more people than tumors of all other organs.
Eliminating tobacco from your life is the best prevention. Even if you smoke not a pack a day, but only half a day, the risk of lung cancer is already reduced by 27%, as the American Medical Association found.
3.Does excess weight affect the development of cancer?
Look at the scales more often! Extra pounds will affect more than just your waist. The American Institute for Cancer Research has found that obesity promotes the development of tumors of the esophagus, kidneys and gallbladder. The fact is that adipose tissue not only serves to preserve energy reserves, it also has a secretory function: fat produces proteins that affect the development of a chronic inflammatory process in the body. And oncological diseases appear against the background of inflammation. In Russia, WHO associates 26% of all cancer cases with obesity.
4.Do exercise help reduce the risk of cancer?
Spend at least half an hour a week training. Sport is on the same level as proper nutrition when it comes to cancer prevention. In the United States, a third of all deaths are attributed to the fact that patients did not follow any diet or pay attention to physical exercise. The American Cancer Society recommends exercising 150 minutes a week at a moderate pace or half as much but at a vigorous pace. However, a study published in the journal Nutrition and Cancer in 2010 shows that even 30 minutes can reduce the risk of breast cancer (which affects one in eight women worldwide) by 35%.
5.How does alcohol affect cancer cells?
Less alcohol! Alcohol has been blamed for causing tumors of the mouth, larynx, liver, rectum and mammary glands. Ethyl alcohol breaks down in the body to acetaldehyde, which is then converted into acetic acid under the action of enzymes. Acetaldehyde is a strong carcinogen. Alcohol is especially harmful for women, as it stimulates the production of estrogens - hormones that affect the growth of breast tissue. Excess estrogen leads to the formation of breast tumors, which means that every extra sip of alcohol increases the risk of getting sick.
6.Which cabbage helps fight cancer?
Love broccoli. Vegetables not only contribute to a healthy diet, but they also help fight cancer. This is also why recommendations for healthy eating contain the rule: half of the daily diet should be vegetables and fruits. Particularly useful are cruciferous vegetables, which contain glucosinolates - substances that, when processed, acquire anti-cancer properties. These vegetables include cabbage: regular cabbage, Brussels sprouts and broccoli.
7. Red meat affects which organ cancer?
The more vegetables you eat, the less red meat you put on your plate. Research has confirmed that people who eat more than 500g of red meat per week have a higher risk of developing colorectal cancer.
8.Which of the proposed remedies protect against skin cancer?
Stock up on sunscreen! Women aged 18–36 are especially susceptible to melanoma, the most dangerous form of skin cancer. In Russia, in just 10 years, the incidence of melanoma has increased by 26%, world statistics show an even greater increase. Both tanning equipment and sun rays are blamed for this. The danger can be minimized with a simple tube of sunscreen. A 2010 study in the Journal of Clinical Oncology confirmed that people who regularly apply a special cream have half the incidence of melanoma than those who neglect such cosmetics.
You need to choose a cream with a protection factor of SPF 15, apply it even in winter and even in cloudy weather (the procedure should turn into the same habit as brushing your teeth), and also not expose it to the sun's rays from 10 a.m. to 4 p.m.
9. Do you think stress affects the development of cancer?
Stress itself does not cause cancer, but it weakens the entire body and creates conditions for the development of this disease. Research has shown that constant worry alters the activity of immune cells responsible for triggering the fight-and-flight mechanism. As a result, a large amount of cortisol, monocytes and neutrophils, which are responsible for inflammatory processes, constantly circulate in the blood. And as already mentioned, chronic inflammatory processes can lead to the formation of cancer cells.

Often this symptom provokes vomiting, which emptys the stomach of its contents.
One-time and mild nausea after eating is a single feeling of different etiology that disappears on its own.
If regular and recurring nausea occurs, the patient has problems with the functionality of the digestive system:
The somatic cause of nausea that occurs during or after eating requires urgent treatment. Before prescribing a treatment regimen, the gastroenterologist establishes the exact etiology of the development of this symptom.
Somatic reasons for feeling nauseated after eating include stomach dysfunction. With this diagnosis, additional symptoms appear:
The feeling of discomfort in question may appear immediately while eating. This indicates an inflammatory process occurring in the liver and gall bladder.
With this diagnosis, there is additionally severe pain on the right side of the abdomen, a feeling of bitterness in the mouth, and a distension in the stomach. Flatulence is another symptom that appears after eating.
If the appendix is inflamed, the patient may feel sick after any meal. Additionally, vomiting appears. With this diagnosis, abdominal pain is not often localized to the right.
It may be of an uncertain nature. But after some time, against the background of high temperature, the pain moves to the right epigastrium.
The causes of nausea after eating may be associated with pancreatitis. In this case, a typical pain appears that encircles the entire body.
If the pathology constantly manifests itself in a chronic form, there is no vomiting. With this diagnosis, the patient may complain of bloating.
If the reasons why you feel sick after every meal are associated with infection, the clinical picture in question begins to appear an hour after eating. The symptoms may intensify and vomiting may occur.
If the infection has penetrated the digestive tract, the patient experiences diarrhea, fever, and pain in the navel.
If you feel sick for an hour or the whole day, your doctor may diagnose myocardial infarction. In this case, urgent treatment is required.
Other reasons why you feel sick after eating are associated with various forms of kidney failure.
At an early stage of the disease, nausea appears suddenly, all the time, regardless of food intake. Kidney pathology additionally provokes shooting and aching pain in the lower back, chills.
The causes of nausea that occurs after eating are associated with various forms of hypertension. More often, the symptom in question bothers the patient in the morning. At the same time, the whole body swells, and dizziness is felt.
Hypothyroidism is a periodic feeling of nausea during and after eating, which makes the patient weaker. He refuses food, but his body weight does not decrease.
Patients with this diagnosis often experience significant weight gain. Additionally, lethargy, drowsiness and chills appear.
Gastroenterologists identify physiological causes in a separate group, against the background of which one feels sick from any food:
Separately, gastroenterologists consider the reasons why fatty foods make you sick. Fat is an important nutrient, a source of energy and “good” cholesterol.
Fat is also a catalyst for metabolic processes occurring in the body. The nutritional value of food is the presence of fat in it. Without them, it is impossible to absorb fat-soluble vitamins, including A, D, E and K.
Nausea and vomiting after eating a lot of fatty foods develops due to pancreatic insufficiency. If such symptoms occur all the time and after every meal of fatty foods, the risk of developing pancreatitis increases.
Due to a deficiency of pancreatic juice, the process of fat absorption is disrupted. This is due to the fact that the intestines are only able to digest 20% of all fats.
As the patient ages, the endocrine function of the pancreas decreases, which helps to reduce its secretion.
With dyskinesia, the process of bile secretion is disrupted. This can lead to cholelithiasis.
If the patient continues to eat fatty foods, the flow of bile will be disrupted and the body will not be able to digest fats. Patients with this diagnosis are indicated for treatment with enzyme agents.
Nausea and vomiting that appear after eating fatty foods can be caused by inorganic factors weakening secretory activity.
The latter phenomenon develops against the background of abuse of high-calorie foods and tannins, and a sedentary lifestyle.
Patients with such disorders are prescribed a diet. The oil used for frying greatly increases the calorie content of food.
The body is not able to digest the fats that enter the body. The digestive system has limited motor capabilities to remove the necessary secretions.
Against the background of abundant fried and fatty foods, the gastrointestinal tract is overloaded. After eating such food, the digestive system begins to work with increased load.
Against the backdrop of large volumes of food, a shortage of necessary enzymes is provoked, without which normal processing of food and timely emptying of the stomach is impossible.
Intestinal absorption is impaired. When fatty foods are retained in the duodenum, stagnation in the intestines is provoked. At the same time, gases accumulate and pressure in the peritoneum increases.
Stagnation is dangerous because it leads to self-poisoning of the body. In this case, nausea is the main symptom, against which periodic vomiting develops. Its nature of manifestation may be different.
With prolonged stagnation of food, foul-smelling belching and heaviness in the stomach are disturbing. At the same time, fecal stones and constipation form. After such a process, the patient may develop hemorrhoids.
If nausea after eating bothers a patient who has an ulcer or gastritis, gentle nutrition is indicated. The course of these pathologies should be constantly monitored by a gastroenterologist.
If after diet therapy and drug treatment the disease worsens, the patient begins to suffer more from nausea, a re-examination is carried out.
The doctor may prescribe gastroscopy, laboratory blood tests, and ultrasound of the peritoneal organs. Treatment of ulcers with timely diagnosis leads to a favorable prognosis.
The patient is prescribed medication for nausea. The treatment regimen also includes drugs that promote healing of ulcers.
After nausea caused by an ulcer, taking enzyme agents over a long period is indicated.
If a patient vomits after eating due to gallbladder pathology, what should be done? With this diagnosis, it is recommended to eat fractionally. To make an accurate diagnosis, an ultrasound is prescribed.
If the examination reveals stones, symptomatic treatment aimed at eliminating nausea, vomiting, and pain is supplemented by surgery.
If the patient feels nauseous after eating food, and the abdomen tightens with widespread, circular pain, the doctor may suspect pancreatitis.
What should patients with this diagnosis do? Treatment of pancreatitis is carried out on an outpatient or inpatient basis.
The main goal of therapy is the fermentation and breakdown of food. Nausea and other signs of pancreatitis are eliminated with anti-inflammatory drugs. Treatment includes following a strict diet.
If you experience nausea during pancreatitis after eating certain foods, you should inform your doctor. Perhaps he will prescribe a new, more effective treatment.
With this pathology, you cannot drink folk remedies on your own. Herbal medicine is carried out under the strict supervision of a gastroenterologist. The main principles of therapy for pancreatitis are cold, rest and hunger.
If a patient feels nauseous and refuses to eat, complaining of constant vomiting, what to do? A similar clinical picture occurs with appendicitis. His treatment consists of unscheduled surgery.
More often, nausea with appendicitis is constant, and the patient is bothered by the stomach on the right.
If the pain is mild, then until the doctor arrives, it is recommended not to drink the painkiller, limiting the patient’s food and drink.
Otherwise, the clinical manifestation of appendicitis will be disrupted and upon arrival of the ambulance, the patient may only be left with nausea and vomiting.
After examining the patient, the doctor makes a decision on subsequent treatment.
To prevent its rupture, unscheduled surgical treatment is indicated. In the postoperative period, nausea and other symptoms of appendicitis disappear.
If the symptoms in question are caused by intestinal intoxication, it is recommended to induce vomiting to eliminate it. For this purpose, drinking plenty of fluids is recommended.
If the vestibular apparatus is malfunctioning, the patient begins to suffer from nausea and dizziness. Treatment is carried out by a neurologist using symptomatic drugs (Betaserc, Metoclopramide).
Hypertension, which causes nausea, is treated individually by a therapist. Antihypertensive drugs are taken continuously, and often for life, to reduce the risk of stroke.
Cardiac diseases, which are accompanied by nausea, shortness of breath, pain on the left, a feeling of squeezing, are treated by a cardiologist after making an accurate diagnosis.
To eliminate nausea caused by endocrine pathologies, taking medications that regulate hormonal balance is indicated.
Renal pathologies, during the development of which the patient suffers from nausea, pain, and high fever, are treated by a urologist.
If stones or sand are detected in the patient, anti-inflammatory drugs, physiotherapy are indicated, and the menu is adjusted.
If the patient is worried about a migraine, which is accompanied by attacks of nausea, taking medications of the triptan group - Metoclopramide and Sumatriptan - is indicated.
Products with tyramine are also excluded from the menu.
During pregnancy, nausea is a normal reaction of the body to conception. More often, the body’s condition returns to normal by the 2nd trimester.
In more severe cases, the symptom is treated with medication or the pregnant woman is hospitalized.
Prevention of the development of attacks of nausea is aimed at eliminating the cause of its occurrence. To prevent the appearance of the clinic in question, it is recommended to lead a healthy lifestyle:
Before taking any medication, it is recommended to consult with your doctor and read the instructions for use.
Pregnant women need to minimize stress factors, fatigue, and stress. If you are allergic to certain foods, you should avoid them if possible.
If, against the background of prescribed therapy, the manifestation of the gag reflex has increased, or general health has worsened, it is recommended to inform the doctor about this.
Many people are familiar with the problem of frequent nausea that occurs “just like that,” for no apparent reason. Of course, when we, for example, catch a cold or are poisoned, we are not surprised by prolonged nausea and even more unpleasant phenomena. But why can we feel sick if, at first glance, we feel fine otherwise? In fact, there can be many causes of nausea, and often the unpleasant symptom itself is associated with serious, dangerous diseases. In order to recognize a dangerous disease in time, it is important to understand why you feel sick every day, frequent nausea is a sign of what it could be, and immediately begin searching for the true cause. To do this, we will talk about the most common causes of nausea.
Regardless of the type of nausea and its duration, when we talk about nausea during the day for no reason, we mean the absence of a clear reason: poisoning, overeating, etc. Many diseases that occur latently may indicate dangerous changes occurring in various human organs and systems. Nausea does not occur without any reason, so it is extremely important to determine why you may feel nauseous.
Nausea can be different - mild, severe, long-lasting, frequent, almost continuous. In itself, this condition is extremely unpleasant for a person, but when attacks of nausea occur frequently, interfere with normal activity and create fear for one’s own health, the cause must be found as quickly as possible. Frequent nausea that you experience for several days in a row, or even for a longer period, should not go unnoticed by a specialist.

An unpleasant sensation that occurs in the epigastric region and pharynx often occurs due to problems with the gastrointestinal tract. Moreover, this is by no means always connected in any way with poisoning. There are many gastrointestinal diseases that cause frequent nausea. Moreover, this often occurs.
Gastritis, stomach ulcers, pancreatitis, appendicitis, cholecystitis, duodenitis can sometimes be the answer to the question of why you sometimes feel sick for no reason.
Pancreatitis is an inflammation of the pancreas, often accompanied by the unpleasant symptom we describe, along with severe bloating. The necessary enzymes do not enter the stomach cavity, and food is not completely digested.
Stomach ulcer is one of the most common answers to the question “why do I often feel sick.” This may also include a burning sensation and frequent heartburn. The lining of the stomach is damaged, which leads to acid entering the tissue of the esophagus. The body requires an empty stomach to complete the digestion process. It is important not to delay and consult a doctor.
Inflammation of the intestinal appendix, or in other words, appendicitis, due to which toxins and pus accumulate in the gastrointestinal tract, often causes an attack of nausea, the causes of which lie in a sharp change in the intestinal microflora. If, in addition, severe abdominal pain, dizziness, weakness and a strong increase in temperature appear, you should not hesitate.

Diseases of the central nervous system can cause nausea during the day. The vomiting center is located in the brain, so problems with the nervous system can cause an unpleasant symptom. Skull injuries, concussions, meningitis, migraines, increased intracranial pressure, seasickness - the list goes on and on.
Hypertension often causes nausea. In addition to the symptom itself, you may experience dizziness and severe fatigue.
Osteochondrosis is sometimes what causes nausea every day. The disease often appears in office workers who are forced to spend a long time in one uncomfortable position. Sometimes dizziness is added to the main symptom.
Some medications cause nausea. Often such a side effect is written about in the annotation for the product.

It would seem that you are healthy, but the unpleasant condition is repeated with unenviable regularity. What's the matter?
Nausea without pain can be caused by a weak vestibular system. Many people get motion sickness in transport, after prolonged movements, in this case you need to worry in advance and purchase special tablets.
Why sometimes you feel sick for no reason - the answer may be psychological problems. For example, often an unpleasant condition is explained by stress, fear, or nervous tension. As soon as you calm down and do some breathing exercises, the feeling should go away.
A person who moves from his habitat to the opposite one often experiences slight nausea. Often the symptom occurs in an area where you have never been before. A couple of days of a “cloudy” state is normal. But if such nausea lasts longer, it is better to consult a specialist.
Many of us wonder why we feel sick just like that, if everything is fine with our health, and we lead an ordinary lifestyle and do not leave our hometown. The answer may lie in this very lifestyle, or more precisely, in inactive and improper physical activity. Office workers, even those who do not suffer from osteochondrosis, can often look for the causes of severe nausea. An uncomfortable posture in front of a computer and other office equipment leads to stiff shoulders, neck, arms, and sometimes headaches.
If you often experience signs of nausea, you may need to reconsider your diet. Hunger, overeating, too much love for sweets often become causes of severe nausea.
The causes of nausea can always be completely different, the main thing is to consult a specialist and not ignore the problem. You should not “prescribe” yourself medications for an unpleasant phenomenon; it is necessary to eliminate exactly the cause. Nausea, like many other symptoms, does not occur out of nowhere, but indicates some changes in the body.
Nausea is a peculiar unpleasant sensation in the epigastric region, chest, and oral cavity, which often precedes vomiting and is often accompanied by general weakness, sweating, increased salivation, cold extremities, pale skin, and decreased blood pressure.
Possible causes not related to any disease:
1. Overeating and/or regularly eating foods that are very high in fat;
2. Side effects of medications and penetration of toxic substances into the body;
3. Psychogenic reactions: fear and anxiety, hysteria;
4. Kinetosis (seasickness), accompanied by a feeling of nausea and motion sickness;
5. Pregnancy (morning sickness normally goes away by the end of the first trimester);
6. Exposure to smoke, toxic fumes and various harmful substances;
7. Sunstroke, hyperthermia.
Diseases that cause nausea are very diverse and can be associated with the digestive, nervous, reproductive, cardiovascular and endocrine systems.
Most often, nausea develops due to pathologies of the gastrointestinal tract, including:
1. acute surgical diseases: peritonitis, appendicitis, acute pancreatitis, acute intestinal obstruction, gastrointestinal bleeding, acute cholecystitis;
2. chronic diseases: gastroesophageal reflux disease (GERD) and hiatal hernia, gastritis, peptic ulcer of the stomach and duodenum, enterocolitis, duodenitis, cholelithiasis, inflammatory bowel disease (Crohn's disease, ulcerative colitis), irritable bowel syndrome, chronic pancreatitis ;
3. malformations of the gastrointestinal tract: narrowing of the pylorus (stenosis), fusion of a section of the gastrointestinal tract (atresia), developmental defects of the pancreas;
4. gastrointestinal tract infections: viral gastroenteritis, food toxic infections, helminthiases;
5. foreign bodies of the stomach, esophagus, intestines;
6. functional disorders accompanied by impaired motor function of the stomach and intestines;
7. liver diseases (hepatitis, cirrhosis of the liver);
8. food intolerances or food allergies.
In addition to disruption of the gastrointestinal tract, nausea can be caused by diseases of other organs and systems:
1. Diseases of the central nervous system: brain tumors and injuries, brain infections (encephalitis, meningitis), increased intracranial pressure.
2. Diseases of the cardiovascular system: hypertension, heart failure, myocardial infarction.
3. Diseases of the inner ear: Meniere's disease, labyrinthitis.
4. Diseases of the endocrine system: in diabetes mellitus – ketoacidosis; thyrotoxicosis, adrenal insufficiency, phenylketonuria.
5. Kidney diseases (urolithiasis, renal failure);
Nausea is associated with cancer treatment (chemotherapy and radiation therapy), imbalance of blood electrolytes, and migraines.
Nausea can be a manifestation of such emergency conditions as poisoning, diabetic ketoacidosis, intestinal obstruction, cerebral hemorrhage, acute cardiovascular pathology, renal failure, liver failure, sepsis.
Most often, nausea does not appear independently, but in combination with other symptoms: abdominal pain, belching, diarrhea, increased gas formation, dyspepsia, vomiting, muscle pain, dizziness, severe fatigue, fever and chills, headache, yellowing of the skin and sclera.
Particular attention should be paid to the combination of nausea with the following symptoms: black stools or the presence of blood in the stool, the presence of blood in the vomit, severe abdominal pain, difficulty breathing, fainting, impaired consciousness, high body temperature (more than 38.5 ° C), rapid pulse, frequent shallow breathing, severe headache , stiff neck. The appearance of these symptoms indicates the development of a life-threatening condition, if detected, you should immediately consult a doctor. You should also definitely see a doctor if you feel sick after a head injury.
Nausea is a nonspecific symptom of many diseases; therefore, it has diagnostic value only in conjunction with other signs of the disease (for example, with signs of peritoneal irritation in acute appendicitis).
To determine the direction of the examination, it is necessary to conduct an active interview with the patient. So, if nausea is accompanied by other dyspeptic manifestations (belching, a feeling of heaviness in the epigastric region, etc.) and a relationship is identified between the occurrence of nausea and food intake, diseases of the digestive system should be assumed (gastritis, cholecystitis, pancreatitis, stomach tumor, etc.) and conduct a gastroenterological examination; when nausea is combined with headache, sensitivity or movement disorders, a neurological examination, etc. is necessary.
Determine what medications the patient took. Drugs that often cause nausea and vomiting include analgesics, cardiovascular drugs, hormonal agents, antibiotics, drugs that primarily act on the central nervous system, and antineoplastic agents. Drug use or withdrawal may also cause nausea or vomiting. If discontinuation of a drug is accompanied by the disappearance of nausea, we can assume that this disorder is associated with taking the drug, but it is necessary to ensure that there are no symptoms for a significant period of time after discontinuation of the drug.
An objective examination reveals an “acute abdomen” and other life-threatening conditions. If the cause of nausea has not been established, a laboratory examination is performed:
1. general blood test (possible anemia, leukocytosis, accelerated ESR in case of gastric ulcer, duodenal ulcer, ulcerative colitis, etc.);
2. electrolytes, urea, creatinine (studied to diagnose kidney function and assess fluid and electrolyte disorders);
3. biochemical indicators of liver function: ALT (alanine aminotransferase), AST (aspartate aminotransferase), gamma glutamyl transpeptidase, total protein level in the blood, blood albumin, bilirubin);
4. blood glucose (normal values are 3.3-5.5 mmol/l, an increase in glucose levels indicates the likelihood of diabetes mellitus);
5. biochemical indicators of pancreatic function: alpha-amylase enzyme, lipase enzyme;
6. antibodies to Helicobacter pylori (to detect gastric ulcers associated with Helicobacter pylori infection);
7. In the analysis of stool when diagnosing diseases of the digestive system, the quantity, consistency and shape, color, smell, impurities, presence of mucus, pH are assessed; at the chemical level, the content of blood, bilirubin, stercobilin, and protein is determined;
8. The study of intestinal microflora is carried out when diagnosing intestinal dysbiosis.
The plan for further examination depends on the patient’s age and clinical manifestations. It should be especially careful if nausea and vomiting occur for a long time.
Pregnancy tests should be performed in women of childbearing age.
Sometimes a general urine test, a toxicological study, cultures, and a study of the function of the endocrine glands (TSH and thyroid hormone levels, morning fasting cortisol levels) are needed.
To exclude diseases of the gastrointestinal tract, diseases of the liver and biliary tract, a survey radiography of the abdominal cavity, examination of the stomach and intestines with barium, ultrasound of the abdominal organs, CT and endoscopic examinations are performed.
FEGDS (fibrogastroduodenoscopy) is intended primarily to exclude obstruction, gastric or duodenal ulcers or other organic pathology.
Colonoscopy is necessary to identify nonspecific ulcerative colitis, Crohn's disease, chronic non-ulcerative colitis, if a tumor process is suspected.
pH-metry is carried out to study the secretory function of the stomach if gastritis or gastric ulcer is suspected.
Rectomanoscopy is used for diseases of the rectum.
If a neurological disorder is suspected (migraine, increased intracranial pressure, pathology of the inner ear), which can cause constant or periodic nausea, a clinical neurological examination should be performed, to exclude increased intracranial pressure by examining the fundus of the eye or conducting magnetic resonance imaging of the brain.
Sometimes esophageal manometry, 24-hour esophageal pH-metry, a study of gastric motility and evacuation function, and sometimes electrogastrography and a study of small intestinal motility are required to make a diagnosis.
If psychiatric illnesses that cause constant or recurrent nausea, anxiety disorders, depression, or eating disorders are suspected, a consultation with a psychiatrist is prescribed.
Since nausea is a symptom, its treatment method depends on the cause or underlying disease. If you suspect a disease, it is important not to self-medicate, since nausea may be associated with emergency conditions or the initial manifestation of severe pathology, which require immediate consultation with a doctor and the initiation of specific treatment under medical supervision.
If the cause is not related to the disease, it is necessary to eliminate the harmful factor (sun, smoke, excess food) as quickly as possible.
For seasickness, it is possible to use scopalamine in the form of a skin patch 5-6 hours before the start of the trip.
To eliminate nausea in such cases, it is possible to use folk remedies:
For nausea and vomiting in pregnant women, it is recommended to eat little and often. In the morning, drink only water with lemon or slightly sweetened juice, and eat crackers.
A proven remedy for nausea is green tea.
Grate ginger root and add to dishes.
Before meals, drink 0.25-0.5 tablespoons of fresh potato juice.
Pour a glass of boiling water over a tablespoon of peppermint leaf. Let it brew for two hours. Take the tincture one tablespoon three times a day.
Boil a teaspoon of dill seeds in 200 ml of water. Take in case of poisoning or stomach upsets.
Pour a glass of boiling water into 4 teaspoons of dry crushed lemon balm herb. Leave for several hours. Drink ½ cup four times a day before meals.
Pour 400 ml of cold water into two teaspoons of three-leaf watch and leave for eight hours. Use within 24 hours. Used for nausea to stimulate digestion.
In some cases, if left untreated, nausea can lead to complications such as dehydration (impaired water and electrolyte balance in the body) and nutritional deficiencies in the body. As a rule, this is due to the inability to retain water or food in the body, as well as a lack of appetite.
Depending on the accompanying symptoms, you may need to consult a therapist, gastroenterologist, neurologist, psychiatrist, toxicologist, endocrinologist, or allergist.
