A clinical review of the syndrome of anorexia nervosa is made, giving emphasis to its concept, development and clinical picture. It is a disorder that appears commonly in adolescents without an exaggerated obesity and with just a discrete overweight. Studies have been conducted that show a significant relation between the symptoms and the interpersonal functioning of the anorexic adolescents, since they tend to be isolated or to be accompanied by younger persons. The obesive compulsive disorders associated or not with food are also characterisitcs of this picture. The restricted diet leads to important biological and physical changes, among which the alteration of the hypothalamic and endocrine system, which gives rise to the appareance of signs and symptoms such as amenorrhea, intolerance to cold and hypotension, is stressed. The neurochemical changes present in anorexia nervosa have also been attributed to malnutrition and it is possible that they may perpetuate the conduct alterations.
