Bulimia refers to recurrent episodes of binge eating behavior in which a large amount of food is eaten in a short period of time and cannot be controlled even if one realizes that it is abnormal during the binge, which can be terminated by somatic discomfort, such as abdominal pain and nausea, followed by emotional disturbances, and sometimes by finding ways to vomit out after eating in order to prevent weight gain. The disease should also first rule out excessive drinking and eating due to other somatic disorders, such as endocrine disorders, epilepsy, and mesencephalic lesions. The exact cause of bulimia is not completely clear, some children may initially be caused by psychological factors, for example, when the psychological loneliness, due to family discord or study pressure caused by internal depression, tension, eating makes them feel temporarily relaxed, comforted, pleasant, in the brain center after the formation of a conditioned reflex, so they will often take the method of eating to make themselves find this good feeling, and over time Then they will form a gluttony, causing the brain ingestion center to control the ingestion disorder, and finally reach the degree that they can not control themselves. These children need to seek medical attention as soon as possible, after systematic medication and psychotherapy, most of them can improve until they are cured, such as antidepressants, psychotherapy can be used biofeedback, positive reinforcement, systematic desensitization, cognitive methods. Parents should create a harmonious and relaxed family environment, encourage their children to eat normally, and not look too concerned and anxious during bulimic episodes.
