Bulimia nervosa is a serious condition that, if left untreated, can cause great harm to the physical and mental health of the patient. Patients with bulimia nervosa mainly show recurrent episodes of desire to eat and binge eating behavior, and the occurrence of the disease is closely related to psychosomatic factors. Hypothalamic dysfunction can also induce the occurrence of anorexia nervosa. Clinically, behavioral therapy, medication, and somatic therapy can be taken to help relieve the symptoms of bulimia nervosa.
