An eructation is the sudden exhalation of gases from the stomach or esophagus, accompanied by a characteristic sound. Belching is included in the range of phenomena united by the common term "pneumatosis of the stomach".
Regurgitation - eructation, accompanied by the release of food or gastric juice into the pharynx or mouth and not accompanied by nausea or other vegetative disorders, while there is no contraction of the diaphragm.
Causes of belching
If the burp is persistent enough and is associated with the habitual ingestion of patients with air, which, going outside, to some extent facilitates the patient's condition, in these cases it is a question of aerophagy (nervous belch). With aerophagy, the process of swallowing air is accelerated, there are unpleasant sensations that decrease with belching. An eructation can become an obsessive phenomenon, accompanied by significant sound manifestations, which, naturally, causes stress in patients.
In the framework of these disorders, it should be noted gastrocardial syndrome Remkhelda (the so-called gastrointestinal neurosis), which manifests itself as aerophagia, discomfort and pain in the abdominal area in combination with cardial manifestations. All these disorders occur against a background of a number of vegetative disorders - hyperventilation, tachycardia, extrasystole, hypotension and disorders of the affective sphere of the depressive circle.
Clinical analysis of these phenomena should include careful physical examination of patients, since the elimination of organic disease is particularly necessary here because the phenomenology of the disorders in question often inspires the doctor, even the gastroenterologist, the idea of the possibility of psychogenic disorders.
Often, the appearance of burping is associated with certain characteristics of eating behavior of patients: fast food with insufficient chewing food, ingesting large chunks, smoking during meals, using beverages with a large number of gases dissolved in them. In some patients, the presence of chronic pharyngitis is accompanied by frequent swallowing of the air-Spirit; frequent swallowing movements are possible and when smoking, with hypersalivation.
The pathogenesis of these disorders is mainly due to the penetration of air into the gastrointestinal tract. As is known, every swallowing movement is accompanied by the introduction of air into the stomach. For a short time, it is possible to swallow a large amount of air, which is easily determined by percussion over the left side of the diaphragm. With emotional and autonomic disorders, especially when there is a hyperventilation syndrome in the structure, swallowing movements become more frequent and the process of swallowing air is sharply accelerated. This mechanism appears to be the leading pathogenesis, although the disruption of the gastric digestion process with a large amount of evolved gases is also taken into account. Such mechanisms play a role in a sharp increase in the volume of the abdomen within the framework of hysterical disorders, causing the well-known phenomenon of "imaginary pregnancy" - Alvarez syndrome.
