Chronic gastritis causes inflammation of the stomach mucosa (in some cases it affects deeper layers too). It is a widespread disease accounting for about 35 percent of all digestive system disorders and 80-85 percent of all stomach abnormalities.
Chronic gastritis is sometimes a further development of acute gastritis. However, it usually develops under the influence of various exogenous factors (long-lasting or repeated periods of improper nutrition, spicy and rough food, extremely hot food, insufficient mastication, junk food, immoderate drinking, especially strong drinks, - alcoholic gastritis).
Chronic gastritis may be caused by low-quality food (protein, iron and vitamin deficiency), continuous and uncontrolled treatment by stomach-irritating medicines (Salicylas, Butadionum, Prednisolonum, some antibiotics, Sulfanilamidum), industrial hazardous substances (plumbous compounds, powdered coal, metal dust, etc.), diseases causing tissue hypoxia (chronic circulation insufficiency, pneumosclerosis, anaemia), endogenic intoxications in case of gout or kidney disorder (during which the stomach mucosa discharges urea, uric acid, indole, skatole, etc.), toxins during infectious diseases or when having a local chronic nidus (the so-called eliminative chronic gastritis), hereditary predisposition, etc.
75 percent of all chronic gastritis cases are accompanied by chronic cholecystitis, appendicitis, colitis and other digestive system disorders.
