| Decreased appetite | Anorexia nervosa, intoxication. | |
| Indigestion | Violation of the digestion of proteins, fats, | Atrophic gastritis, peptic ulcer disease, pancreatitis, hepatitis, cirrhosis of the liver |
| Malabsorption of nutrients | Celiac disease, enteritis, colitis. | |
| Violation of metabolism (metabolism) | Prevalence of fracture processes (catabolism) of the processes of synthesis | Severe injuries, burns, cancer, endocrine pathology, diseases of connective tissue. |
Which diseases there is a weight loss:

- Cancer
In all malignant tumors in the body of patients with tumor cell takes metabolites (glucose, lipids, vitamins), which leads to disruption of biochemical processes, depletion of domestic resources and develop cachexia (wasting). It is characterized by sudden weakness, loss of earning capacity and opportunities to serve themselves, lack or loss of appetite. Many cancer patients is cancer cachexia is the immediate cause of death.
Weight loss - as the leading symptom is characteristic of a specific endocrine disease (hyperthyroidism, hypopituitarism, diabetes mellitus type 1). In these conditions is a violation of developing various hormones, which leads to a serious breakdown of metabolic processes in the body.
