Do all patients with depression have gastrointestinal diseases? Why?

Depression patients are often accompanied by digestive tract diseases or symptoms, such as appetite disorders, metabolic abnormalities, functional gastrointestinal diseases, intestinal microbial abnormalities and so on. Although this is often overlooked, some researchers believe that 100% depression and anxiety coincide with digestive system diseases. Mammalian intestine, also called intestinal brain, is a microbial organ. 90%~95% of cells in the intestine are microorganisms (including bacteria, archaea, fungi and some protozoa). Moreover, the main functions of intestinal metabolism, immunity, signal transmission and so on are related to microorganisms, so intestinal tract and intestinal microorganisms can be regarded as a whole to respond to the signals of other organs and affect the functions of other organs. Intestinal microorganisms can play an important role in mental diseases through the bacterial-intestinal-brain axis.

Antibiotics, unhealthy diet and unhealthy lifestyle will destroy the flora and increase the risk of psychological diseases such as depression; And through beneficial bacteria, prebiotics, healthy diet, healthy lifestyle or fecal bacteria transplantation to restore healthy flora, can improve mental health.

Intestinal flora imbalance is the root cause of depression. Only by rebuilding healthy flora can we improve the abnormality of each part of the bacterial-intestinal-brain axis and cure depression. Medical functional gastrointestinal diseases are related to anxiety and depression, but it cannot be said that depression will definitely cause gastrointestinal diseases.

Anxiety, depression and other emotions can lead to gastrointestinal dysfunction. Functional gastroenteropathy refers to a kind of diseases with typical gastrointestinal symptoms without organic lesions. At present, anxiety, depression and fear are the main reasons. Patients with depression can have no symptoms of digestive tract. The main clinical feature of depression is marked and persistent depression, and the clinical manifestations are depression, slow thinking and decreased will activity. Gastrointestinal symptoms are not clinical manifestations of depression.

The direct factor affecting the stomach and intestines is the heart. When the heart is in good condition, the stomach will be well soon, and the stomach will be well soon. The direct factors affecting the heart are the concentration of metabolites in the body and the poison of emotions. Depression patients have high concentration of emotional poisons and poor heart state. So patients with depression have a bad stomach.
