These diseases are increasingly assuming the character of a social problem that affects individuals of both sexes, but which manifests itself most evident in females. Anorexia and bulimia are part of eating disorders, but unlike other less serious events and mostly transient, dependent on life events (unrequited love, a move away from a significant person, etc.), these disorders are real illnesses that are the underlying causes to be found, as we shall see, in family life of the child patients. The eating disorder can therefore rightly be regarded, in these cases, as the most prominent symptom, and often more serious than a complex psychological distress deepest. It is important to remember that anorexia and bulimia should not be confused with pathologies strictly organic, such as dysfunction of the digestive tract, which in a first phase may present similar symptoms.
