In general, this hypovitaminosis is often caused by a lack of vitamins in food, or their poor absorption from the gastrointestinal tract (liver dysfunction, gastrointestinal diseases), or an increase in the body's need for them (pregnancy, obesity). ir postoperative period, chronic infectious diseases, etc.), occurs as a result of a large amount of vitamins leaving the body (increased air and body temperature, heavy physical work and stress). The most serious disease is the deficiency of several vitamins, which is called polyvitaminosis.
