Alamentary dystrophy is a pathological condition of the body that develops under conditions of lack of nutrition. This condition may be temporary or temporary, i.e. permanent. The causes of the development of the disease are improper or insufficient functioning of the digestive system. The permanent causes of the disease include pathological changes in the pancreas and intestines, which result in impaired absorption of vitamins, microelements and nutrients. Due to the lack of proteins, fats, carbohydrates, and minerals received, the patient begins to lose body weight. All human organs and systems receive less nutrients and begin to suffer from malnutrition.
