A young lady presents with repeated episodes of excessive eating followed by purging by use of laxatives. What is the diagnosis?
**Core Concept**
Bulimia nervosa is a complex eating disorder characterized by recurrent episodes of binge eating, followed by compensatory behaviors such as purging, self-induced vomiting, or excessive exercise to prevent weight gain. This cycle of bingeing and purging can lead to severe physical and psychological consequences.
**Why the Correct Answer is Right**
The correct diagnosis of bulimia nervosa is based on the presence of recurrent episodes of binge eating and compensatory behaviors such as purging. Individuals with bulimia nervosa often exhibit a distorted body image and a fear of gaining weight, which drives their behavior. The repeated use of laxatives can lead to electrolyte imbalances, dehydration, and gastrointestinal problems.
**Why Each Wrong Option is Incorrect**
**Option A:** Binge eating disorder is a distinct eating disorder characterized by recurrent episodes of excessive eating, but it does not involve compensatory behaviors such as purging.
**Option B:** Anorexia nervosa is characterized by a restrictive eating pattern and a fear of gaining weight, but it does not involve binge eating or purging.
**Option C:** Avoidant/restrictive food intake disorder is characterized by a lack of interest in eating or avoiding certain foods due to sensory or emotional reasons, but it does not involve binge eating or purging.
**Clinical Pearl / High-Yield Fact**
Bulimia nervosa often co-exists with other mental health conditions such as depression, anxiety, and substance use disorders. A comprehensive treatment plan should address both the eating disorder and any co-occurring mental health issues.
**Correct Answer:** C.
