Preventing nausea without vomiting

If the causes of nausea have been identified and your health has returned to normal, then do not forget about prevention.

Nausea is subjective feeling discomfort in the epigastric (epigastric) region, in the pharynx, accompanied by increased salivation, palpitations, weakness and increased breathing. Nausea usually occurs before vomiting, but can occur without it. There are quite a few reasons for this condition, and they are not always associated with diseases of the digestive system.

The causes of constant nausea are not necessarily due to pathology of the digestive organs

Modern means of self-defense are an impressive list of items that differ in their operating principles. The most popular are those that do not require a license or permission to purchase and use. IN online store Tesakov.com, You can buy self-defense products without a license.

The following types of nausea are distinguished:

• Reflex nausea. Occurs when sensitive fibers from the pharynx, pharynx, esophagus, stomach are irritated, bile ducts, peritoneum, mediastinum, genitals and other reflexogenic zones. This also includes nausea that occurs when the vestibular nuclei are irritated (“motion sickness”).
• Central nausea. In this type of nausea, signals to the vomiting center come directly from the brain. It occurs with organic brain damage, and can also have a psychogenic origin.
• Intoxication nausea. It occurs when the concentration of various substances in the blood increases, both from outside (medicines, poisons, alcohol, bacterial toxins, etc.) and products of the body’s metabolism (ketones, urea, protein breakdown products).

The most likely causes of nausea

Based on the considered pathogenesis, it is clear that there can be many causes of nausea, starting from the cerebral cortex and ending with the genitals.

Let's consider the most likely causes of those situations when you feel sick for no apparent reason. It must be said that such situations occur less frequently in men than in women.

Digestive diseases

In diseases of the gastrointestinal tract, nausea is usually not the only symptom:

In addition to nausea, there are other symptoms

• organic diseases of the stomach and esophagus (peptic ulcer, gastritis, esophagitis, gastroesophageal reflux, foreign bodies of the esophagus, cicatricial stenosis of the esophagus, pylorus and others);
• functional motility disorders (dyspepsia, gastric paresis, increased pressure in the stomach and intestines, overeating, swallowing air with food);
• and biliary tract (cholecystitis, gallstones, dyskinesia);
• intestinal diseases.

In addition to nausea, there may be:

• pain of various types;
• heartburn, belching;
• feeling of fullness in the stomach, bloating;
• stool disorder.

In addition, the connection between nausea and food (or, conversely, hunger) allows one to suspect diseases of the digestive system.

Infections

In the case of an acute course of the infectious process, questions usually do not arise: in addition to nausea, there will be other symptoms:

Vomiting is one of the symptoms of infection

• vomit;
• fever;
• diarrhea;
• manifestations of general intoxication (weakness, sweating, headache).

Nervous system lesions

Nausea may be a sign of increased intracranial pressure, brain tumor, or encephalitis. It helps to suspect this particular cause of nausea:

• presence of headaches;
• blurred vision (double vision, spots, blurred vision);
• sensitivity disorders;
• suffered head injuries.

Intoxication with drugs or other drugs

The most common medications that cause nausea are cytostatics, glycosides, and salicylates. Other drugs may also cause nausea in cases of individual hypersensitivity to them. Nausea like by-effect drugs are often indicated in their instructions.

Disturbance of internal homeostasis

Imbalance in work internal organs —
also a cause of nausea

Excessive accumulation of toxic metabolic products in the blood due to dysfunction of the liver, kidneys, or decompensation diabetes mellitus, disruption thyroid gland.

Vestibulopathy

Nausea that occurs with vestibulopathies:

• paroxysmal positional vertigo syndrome;
• Meniere's disease;
• motion sickness (motion sickness).

In addition to nausea, these syndromes include dizziness, as well as nystagmus (involuntary movements of the eyeballs).

Oncological diseases of any location

Especially in advanced stages.

Food allergies

Or individual intolerance to certain foods.

Psychogenic variant of nausea

For psychogenic nausea no organic diseases brain

Psychogenic nausea occurs quite often, the mechanism of its occurrence is central, that is, impulses to the vomiting center come from the cerebral cortex. There is no organic brain damage. It may manifest itself:

• with increased anxiety, especially in stressful situations;
• for neuroses;
• like reactive nausea at the sight of certain foods (unpleasant associations).

Chronic Nausea and Vomiting Syndrome (CNVS)

Finally, in the international classification functional disorders there is an option - chronic nausea and vomiting syndrome (CNVS) . This is the case when the examination did not reveal any diseases, but the person’s periodic nausea bothers him.

Mechanism of nausea

Nausea occurs at a subthreshold level of irritation of the vomiting center. Moreover, in our brain there are two areas that are responsible for the mechanism of nausea and vomiting.

The vomiting center itself is located in the medulla oblongata and receives impulses from the fibers of the peripheral nervous system (mainly the vagus nerve fibers and sympathetic fibers).

The second zone is the chemoreceptor zone, located in the bottom of the fourth ventricle of the brain, has a rich network of vessels and is closely connected with the circulatory and liquor systems. This zone has a large number of chemical receptors that respond to the presence of toxins, metabolites, medicinal substances. Impulses from this zone are also transmitted to the vomiting center.

Nausea is a consequence of irritation of the vomiting center

In the immediate vicinity of the vomiting center are the nuclei of the respiratory, glossopharyngeal, vasomotor and other nerves. Therefore, irritation of this area is accompanied by increased salivation, sweating, increased breathing and other autonomic reactions.

The vomiting center sends signals through motor neurons to the smooth muscles of the walls of the stomach and esophagus, the diaphragm and the muscles of the abdominal wall.

With nausea, the peristalsis of the stomach sharply decreases, it actually “stops”, while the tone of the duodenum and jejunum increases.

What to do if you are worried about nausea?

Nausea can be a symptom of various diseases, including deadly ones. Therefore, if nausea lasts for several days and is not associated with obvious reasons for you, then you should not postpone your visit to the doctor.

If you have persistent nausea, do not delay visiting your doctor.

Nausea in combination with the following symptoms should be especially alarming:

• loss of appetite, weight loss;
• increased body temperature;
• constant headache;
• abdominal pain.

Only after a full examination can we identify the exact causes of the non-obvious nausea reflex. It will be difficult to make a diagnosis based on one complaint.

Add a comment

Nausea and its causes are familiar to almost every second person on our planet. For everyone, without exception, this is a very unpleasant sensation, radiating into the chest cavity and into the oral cavity. As a rule, a rush of nausea occurs accompanied by chills, increased temperature, excessive sweating, increased salivation, and even decreased blood pressure. All this occurs during an attack of nausea.

Unpleasant sensations

The causes of nausea can vary. And they are not always a link with a specific disease. Nausea and vomiting can be short-term and rare, or a sign of illness. But it is very difficult to determine for sure, especially in the first stages of a vomiting state.

Causes of constant nausea:

• systematic overeating, that is, eating everything that has a high concentration of fat;
• as one of side effects as a result of taking medical supplies. Nausea and vomiting occur, as a rule, due to the ingestion of a large amount of toxins contained in the drugs;
• as a result of psychogenic attacks on the subconscious in the form of fear, anxiety, fear and hysteria;
• If a person suffers from seasickness, it is also called kinetosis. It is its presence that is mainly the main cause of nausea and even vomiting;
• during pregnancy female body hormonally changes. In this state, a woman begins to feel sick in transport, she is haunted by a feeling of nausea from smells, from foods, and so on. In this case, the manifestation of nausea in women, or, as they also say, toxicosis, is provoked by pregnancy, which, as a rule, goes away in the second half of the term;
• You may feel sick from smoke, fumes, toxic fumes harmful substances;
• Nausea and vomiting can also be a consequence of sunstroke, overheating in the sun, that is, hyperthermia.

If there is constant nausea without vomiting all the time, then after a while it goes away as independently and imperceptibly as it appeared, and, accordingly, treatment is not required. It is another matter if nausea and vomiting is more serious and is a sign of a serious illness. There are many diseases, the main symptom of which is nausea and vomiting. In addition, this may be the first sign of disease. So this cannot be ignored.

Possible diseases

All diseases are different. They all have their own symptoms, and each patient feels its course in his own way. Attacks of nausea may be associated with the digestive system, nervous system, reproductive system, cardiovascular system, endocrine system.

Nausea often appears along with diseases of the digestive system and can be associated with serious pathologies.

Serious diseases of surgery:

• pancreatitis;
• appendicitis;
• acute intestinal obstruction;
• stomach bleeding;
• cholecystitis.

Chronic diseases:

• hernias;
• gastritis;
• ulcers;
• colitis;
• chronic form of pancreatitis;
• enterocolitis;
• Crohn's disease;
• gallstone disease.

As well as defects in the form of stenosis, atresia, defects associated with the development of the pancreas.

Infections such as gastroenteritis viruses, toxic infections, helminthiases.

Liver diseases - hepatitis, cirrhosis, individual intolerance to certain types of foods.

In addition, nausea can often be a clear sign diseases that are not associated with food intake and processing.

Nausea occurs with pathologies of the central nervous system, which include the following phenomena:

• tumors in the brain;
• brain infections;
• encephalitis;
• meningitis and meningococcal infection of the brain;
• intracranial pressure.

The unpleasant feeling of nausea in women and men can be caused by diseases of cardio-vascular system. This includes a number of diseases:

• hypertension;
• heart failure;
• heart attack.

Diseases associated with the ear are Meniere's disease, diseases of the labyrinth of the ear.

Also, an unpleasant sensation often accompanies patients with diabetes mellitus and its varieties, such as:

• ketoacidosis;
• thyrotoxicosis;

A kidney patient periodically feels nausea during attacks of urolithiasis or renal failure.

In addition to all these diseases, severe nausea and vomiting accompanies oncological diseases, and after chemotherapy or a procedure radiation therapy Nausea and vomiting may also occur. In this case main role Imbalance of blood electrolytes and migraine play a role in the appearance of a pre-vomiting sensation.

Why does mild nausea occur?

Mild nausea occurs when a person is poisoned, when diabetic ketoacidosis occurs or hemorrhage occurs, and also with cardiovascular pathology, liver failure and sepsis.

It happens that nausea and vomiting does not appear on its own, but has a number of symptoms. Wherein frequent companion nausea may include abdominal pain, belching with an unpleasant clayey odor, diarrhea, chills, trembling, skin rashes, yellowness of the skin, dizziness, severe fatigue, wobbly legs, and so on.

The accompanying symptoms should be taken especially seriously. It could be:

• black stool;
• blood in vomit;
• every day severe pain in the abdominal area;
• lack of air;
• elevated temperature;
• drowsiness;
• headache appears every day;
• fainting;
• pulling muscles.

Nausea for no reason, and even nausea without vomiting - all this may indicate that a disease is developing in the body, which can even be fatal. If any of these symptoms appear, you should see a doctor.

A qualified specialist, first, must listen carefully to the patient. If necessary, ask him those questions, the answer to which could establish a diagnosis. For example, what did he eat and when, in what quantities, are there any diseases, did he hit his head, and so on.

If there is nothing that would clearly indicate the cause of nausea, then the doctor prescribes examinations. The direction of diagnosis depends on the symptoms of nausea.

In addition, during the interview, the doctor clarifies whether the patient has taken any medications or not. It should be borne in mind that most medications have a number of side effects, such as nausea, vomiting, diarrhea, rash, dizziness, etc.

Medicines, side effects

Nausea without vomiting may be caused by medications such as:

• analgesics;
• cardiovascular drugs;
• hormonal drugs;
• antibiotics;
• antitumor drugs;
• narcotic drugs.

It is also worth knowing that if the patient, in the event of any illness, took narcotic drugs, regardless of the dosage, in case of withdrawal, in almost 99% of 100, nausea occurs and vomiting may occur.

Objectivity in the examination is the key to a successful diagnosis and treatment. If none of the options can help establish the cause of nausea, then the doctor prescribes a laboratory examination.

Laboratory examination of the patient

TO laboratory research applies:

1. General blood analysis.
2. Stool analysis.
3. Study of intestinal microflora.

Using this study, you can determine the presence of other diseases or discard their likelihood, and prescribe treatment. Here, for example, according to the results general analysis blood, it is possible to establish the presence of a disease such as anemia or leukocytosis, a gastric ulcer or a disease associated with duodenum. The result of the test for the presence of electrolytes, urea and creatine is carried out to identify kidney diseases. Concerning biochemical analysis, then in this case it is possible to determine the level of protein, blood albumin and bilirubin. The glucose level shows the likelihood of developing diabetes. Tested antibodies in the blood help identify the functioning of the pancreas.

Feces are examined in case of suspected diseases of the digestive system. The intestinal microflora is examined in order to determine the presence of intestinal dysbiosis.

Further treatment is investigated and determined taking into account clinical picture and taking into account the patient's age. The examination is carried out especially carefully in cases where nausea has been present for quite a long time, especially in women who complain of bouts of vomiting, are in childbearing age, the first test that a doctor prescribes is a pregnancy test. After all, pregnancy can cause similar discomfort associated with the restructuring of the body.

But sometimes there can be different reasons other than pregnancy.

In some cases, a urine test, toxicology test, and culture may be necessary. If nausea in women is related to work endocrine system, then a consultation with an endocrinologist and a blood test for the presence of hormones is carried out first.

Once the cause is established, the doctor, if this is his profile, will prescribe appropriate treatment. If the disease is not related to the qualifications of the doctor to whom the patient turned, the patient is referred to other specialists to make an accurate diagnosis.

Therapeutic measures

Nausea goes away on its own for no reason. It's another matter if it is a sign of a disease. Then, along with the elimination of the cause of its appearance, its treatment occurs. The main thing is to ask for help in a timely manner.

Here's how you can relieve nausea:

• if the cause is the sun, sea, food, then, first of all, the very effect of the harmful factor is eliminated;

• if the patient suffers from seasickness, scopolamine in the form of a patch, which is attached to the surface of the skin 5 hours before going to sea, will help cope with nausea and weakness;

• During pregnancy, all that can be used by a woman for nausea is meclozine. This drug can be used in the form of suppositories. In this case, its constituent components bypass the liver and enter through the blood veins in the rectum directly into the blood.

5. Decoctions, infusions prepared based on recipes traditional medicine, will cope perfectly with the surging nausea. Moreover, there is now quite a lot of information about the usefulness and harm of this or that product.

If frequent nausea and vomiting is not a disease, then it is quite easy to cope with. To do this, there is no need to immediately start taking medications.

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. To recognize in time dangerous disease, 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.

Nausea “for no reason”

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 bodies and human 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.

Diseases - signs of nausea

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 in gastrointestinal tract toxins and pus accumulate, often causing 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 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 about something like this side effect This is what is written in the annotation for the product.

Causes of nausea not related to illness

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 strong love cravings for sweets often cause 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 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.

What causes nausea?

Brain Oscillations

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).

Thyroid diseases

For hypothyroidism - reduced function 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 level TSH hormones, T4, T3, and if the indicators are not normal, go to an appointment with an endocrinologist.

Nerves

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.

Intoxication

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 scan. abdominal cavity and kidneys, take urine and blood tests (general and biochemical) to establish the primary suspected area of ​​damage. 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.

Cancer

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!

Viral infection

The body also reacts with nausea to the introduction of bacterial or viral infection, and the latter is stronger, 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.”

Allergy

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.

Wrong dose

Nausea often occurs as a side effect of taking any medicinal product. 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.

hunger strike

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.
