Nausea that often occurs after eating, as well as the urge to vomit and the vomiting itself, is called the emetic syndrome. Nausea is quite normal if it occurs only occasionally. This is a defense mechanism. He tells a person that it is possible to eat, but it is impossible. The most dangerous thing must be thrown out of the stomach immediately to avoid absorption into the blood. From the less dangerous one, there is nausea, but no vomiting. However, in this case, the protective function is also fulfilled: in order to avoid repeated nausea, a person will no longer eat what provoked this unpleasant symptom. But if nausea is constantly tormenting, and there is no connection with certain foods, this should alert. Most likely, the body is not working properly. It can be like a functional disorder that only spoils life, but does not threaten with complications, or it can be a deadly disease. You can find out what the reason is only by the results of the examination, and not by the symptoms, since nausea is a non-specific symptom that appears with a huge number of various diseases and conditions. And not all of them are limited to the gastrointestinal tract.
Causes of nausea
There are many reasons for nausea. These are not only diseases of the digestive system, but also diseases of the brain, inner ear, pregnancy, infections, medication, oncology, and much, much more. But now we will talk about the reasons exclusively gastroenterological. They are the most common causes, and besides, it is for these diseases that nausea after eating is characteristic.
The origin of nausea and vomiting is:
- pancreatic due to enzymes;
- biliary or biliary;
Esophagus . Nausea and vomiting occur when food does not pass into the stomach. This happens with tumors, large scars after an ulcer, sprain, spasm or inflammation of the esophagus. Nausea occurs immediately after eating, and vomiting provokes fluid intake. In vomit, you can see food in the same form in which a person swallowed it, without the admixture of hydrochloric acid.
Stomach . The most common causes are gastritis, peptic ulcer, atrophy and tumors. Nausea is most often associated with abdominal pain. After vomiting, relief often occurs: not only nausea, but also pain syndrome disappears. The vomit is sour.
Pancreas . The two main causes of vomiting are pancreatitis and pancreatic cancer. Nausea is constant, and vomiting is indomitable and repeated. It occurs against the background of severe pain in the abdomen, but does not bring relief.
bile ducts . Nausea occurs after eating fatty foods. If a person ignores this signal and continues to overeat, then vomiting occurs. It is often repeated and does not bring relief. Bile is found in the vomit (an admixture of yellow-green color).
Gatekeeper . This is the transition zone of the stomach into the duodenum. In this place, stenosis or narrowing and obstruction may occur. The reasons are different: an ulcer that has healed with the formation of a large scar, a tumor, an operation. A person is sick for a long time, and then vomiting occurs in a fountain. After that, the nausea completely disappears. Food in the stomach stagnates and swells , so vomiting smells very unpleasant.
Intestine . Becomes can become a source of fecal ( fecaloid ) vomiting. This is possible in very neglected cases with a strong narrowing of the intestine, a violation of its blood supply, and it also happens with a pronounced dysmotility. Nausea from the intestines can occur with almost any intestinal problem, accompanied by bloating and gas formation.
What to do
Most often, a person does the following: he goes to the pharmacy and says that he should be given something for nausea. Such drugs do exist. Antiemetic drugs block the signal to the brain and the nausea goes away. Other drugs, such as itomed , restore the tone and motility of the upper digestive system, and the cause of nausea disappears.
A few reasons why you shouldn’t just block nausea:
- all antiemetic drugs can cause side effects, they should be used with the participation of a doctor;
- the cause of nausea remains unknown; • the cause of nausea is not eliminated (the effect is exclusively symptomatic);
- short-term effect: after a few hours, nausea will return;
- you can miss a dangerous disease by reducing nausea with medication.
It is better to consult a doctor and get checked: donate blood, feces for analysis, undergo gastroscopy or colonoscopy, ultrasound of the abdominal cavity. These studies allow doctors to detect most of the gastrointestinal disorders that cause nausea.
Then treatment is selected, depending on the cause of nausea. For example, if the problem is in the gallbladder and ducts, the doctor will prescribe drugs from the ursodeoxycholic acid group ( ursosan ). If it is in the stomach and intestines, drugs from the rebamipide group ( rebagit ), antibiotic therapy to suppress Helicobacter pylori infection, proton pump inhibitors, etc. will be used.
Most causes of nausea can be eliminated. All you need is to be examined and undergo a course of treatment. This is better than masking the symptoms with pills, constantly suffering from nausea, limiting oneself in nutrition, while risking missing a dangerous disease. It is better to solve health problems in a timely manner: before you are taken to the hospital with complications.
