There is a young girl in junior high school, her mother found that her diet is extremely abnormal over the past year, sometimes suddenly a meal can eat more than a pound of rice, plus a lot of meat, vegetables, just after eating and looking around for snacks to eat, until you eat until your stomach swells and vomit, sometimes not to eat time, suddenly want to eat, eat all the food you can find at home, do not let her eat, then cry, after eating and digging the throat with their fingers to cause vomiting, they know this I know that this is not good and I am afraid of gaining weight, but I just can’t control it. Sometimes she ate normally, but sometimes she ate very little. After a detailed examination, the doctor found that the girl had bulimia. Bulimia refers to recurrent episodes of binge eating behavior, eating large amounts of food in a short period of time, not being able to control herself even when she realizes that it is not normal, and the episodes can be terminated by physical discomfort, such as abdominal pain and nausea, followed by mood disorders, and sometimes trying to vomit 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 to form 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 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.
