In simple words: This is a type of anorexia where a person severely restricts their food intake and is significantly underweight but also has episodes where they eat a large amount of food and then try to get rid of it by vomiting or using laxatives, diuretics, or enemas.

Anorexia nervosa, binge eating/purging type is a serious eating disorder characterized by a significantly low body weight for age, sex, developmental trajectory, and physical health, along with an intense fear of gaining weight or becoming fat. Individuals with this subtype engage in both restrictive eating patterns and episodes of binge eating followed by compensatory purging behaviors such as self-induced vomiting, misuse of laxatives, diuretics, or enemas. This combination of behaviors distinguishes it from restrictive anorexia nervosa, where purging is not present, and from bulimia nervosa, where individuals are typically at a normal or higher weight.

Example 1: A 17-year-old female presents with extreme weight loss, amenorrhea, and bradycardia. She admits to restricting food intake and engaging in self-induced vomiting after meals., A 25-year-old male, despite being significantly underweight, expresses intense fear of gaining weight. He engages in both restrictive eating and periods of binge eating followed by laxative abuse., A 40-year-old female presents with electrolyte imbalance and complaints of fatigue and dizziness. She is found to have a history of restrictive eating, binge episodes, and purging via diuretic use.

Documentation should include details of the patient's weight history, eating patterns, body image concerns, fear of weight gain, and any purging behaviors.Physical exam findings, laboratory results (e.g., electrolyte levels), and mental health assessments should also be documented.
