Bulimia nervosa is a mental illness that is treated with medication, nutritional therapy, and psychotherapy. Through comprehensive treatment, it can improve the condition and avoid continuous aggravation of the disease. 1. Drug treatment: antidepressants can be used for treatment, such as fluoxetine, paroxetine, etc., which can reduce the activity of the vagus nerve, so that the patient can restore the normal sense of satiety, reduce food intake, and also alleviate the accompanying symptoms of depression. 2. Nutritional therapy: The main purpose is to establish a standardized diet plan for patients, reduce the frequency of dieting episodes, and improve the overeating and vomiting behaviors caused by dieting. 3. Psychological treatment: such as cognitive behavioral therapy and family therapy, etc., to reduce the patient’s concern about his body shape and weight, change the patient’s cognition, establish healthy eating habits, correct incorrect eating behaviors, and prevent the disease from recurring. During treatment, it is important to follow the doctor’s instructions, use medication in a safe and reasonable manner, and do a good job in all aspects of care, and regularly visit the doctor for review. The use of drugs need to be under the guidance of a physician, not blindly taken on their own to avoid adverse reactions.
