How the stomach affects the work

Stress stomach ulcers

For the

first time the link between stress and stomach ulcer was established by English scientist Swan J. as early as 1823. The term “stress ulcer” introduced G. Selye’s medical practice in 1936. Presently, stress ulcer refers to superficial, usually multiple lesions of the gastric and duodenal mucosa that occur against the background of burns, severe injuries and critical states. Only very severe stress leads to ulcers.

How it happens:

  1. Stress excites the middle brain.
  2. The

  3. pituitary gland is activated
  4. The production of adrenocorticotropic hormone is enhanced.
  5. The production of adrenal hormones increases.
  6. Gastric secretion is enhanced – more pepsin and hydrochloric acid are released.
  7. Mucosal corrosion.
  8. Vascular spasm and inadequate mucosal nutrition.
  9. One in five patients has stress ulcers bleeding.

Depression and stomach

Depression and anxiety have a frequent connection with the stomach. Sometimes stomach diseases develop primary: persistent pain and other symptoms cause depression. In other cases, anxiety first appears, and then there are functional dyspeptic disorders. Senestoipochondric depression is often accompanied by discomfort in the digestive region. Patients complain of suddenly emerging sensation of stomach overcrowding. Simultaneously, there appears a “com” in the throat, a “com” in the abdomen, a shaking of the hands, a heartbeat. Pains are possible, but usually they do not have a clear localization: the sufferer cannot indicate that he has pain, stomach or intestines. Patients with senestoipochondric depression are confident they are sick, although tests and instrumental studies do not show organic stomach pathology. Such people do not believe the results of diagnosis, often suspect the “conspiracy” of doctors or the entire world health system, visit many clinics and specialists. A gastroenterologist cannot help in this situation: such patients need the services of a psychiatrist.

How does the stomach affect the brain?

The stomach and gut contain more than 100 million nerve cells — more than the spinal cord or the entire peripheral nervous system. Many nerve fibers are associated with the brain. The nerve endings in the stomach are under a layer of mucosa, having a certain thickness.

In almost all stomach diseases, the amount of mucus decreases, exposing the nerve endings before action of hydrochloric acid or other irritants. Thus, the nerve fibers of the stomach are excited and transmit the received signal to the brain. We need to protect and restore the mucosa to get rid of the disease and reduce sensitivity. For this purpose, drugs from the rebamipid group (rebagitis) are used, which promote the regeneration of mucus and the mucosa itself.


stomach receives innervation from the sympathetic and parasympathetic nervous system. It regulates its function. In turn, the organs of the digestive system give communication back to the brain: they regulate eating behavior, can influence mood — improve it (after eating) or make it worse (in a state of hunger).

Up to 90% of all serotonin produced by the body is produced in the gut. This substance is called the “joy hormone”. Drugs that increase serotonin levels in the body are used to treat depression. But with bad mood, the gastrointestinal tract can cope and without any medication, unless the person tortures it by hunger, stress or bad food.
