Stress, anxiety, overwork and overwork will ALWAYS affect digestion. The balance of the gut-brain axis is disturbed. Stress really affects more than we think.

First, the adrenal glands release adrenaline and cortisol into the blood. As basic stress hormones, affect the state of microflora. The criterion of intestinal health is the diversity of microflora. Therefore, the normalization of nutrition in general is important.
⠀
In healthy people, the bacteriological diversity is great, in stress it will change. Funnily enough, the gut continues to function even when there is no connection to the brain and spinal cord. The intestinal response itself regulates the response along the gastrointestinal tract — from the esophagus to the intestine and rectum. Uses the same as the brain: a web of neural chains, neurotransmitters and various proteins.
⠀
Secondly, the work of the digestive tract is disturbed.
⠀
Digestion is a complex process, there is a separate neural network for its regulation. The digestive nervous system is responsible for the mechanical mixing of food, coordinates the contraction of the circular muscle and all the sphincters of the pleura of the intestine in order to ensure the progressive advancement of food, it also maintains the different biochemical environment and acidity levels within each section of the digestive tract, providing enzymes with the necessary conditions.
⠀
Stress affects peristalsis and its work = there is no correct work, assimilation. The movement of the intestinal walls is disturbed, food is delayed for a long time, is not digested, the secretion of digestive enzymes is reduced. We get a small trition from non-assimilation.
⠀
Permeability of the mucous membrane = passes elements that normally should not enter the bloodstream. Often the level of IgA decreases = the body is exposed to viruses and bacteria = the mucous membranes of the gastrointestinal tract are damaged = inflammation develops. Esophagitis, heartburn, gastritis, colitis, IBS, stagnation of bile, bloating? Who has what. Microflora is suppressed.
