Not true of Anorexia nervosa
**Core Concept**
Anorexia nervosa is a complex eating disorder characterized by a distorted body image and an intense fear of gaining weight, leading to restrictive eating habits and significant weight loss. It is a multifactorial disorder involving psychological, social, and biological factors.
**Why the Correct Answer is Right**
The correct answer is related to the pathophysiology and clinical features of anorexia nervosa. Individuals with anorexia nervosa typically exhibit a preoccupation with weight and body shape, which is not a feature of other eating disorders such as bulimia nervosa. In anorexia nervosa, the restrictive eating pattern is often accompanied by a significant reduction in caloric intake, leading to weight loss and potentially life-threatening complications such as malnutrition and electrolyte imbalances.
**Why Each Wrong Option is Incorrect**
* **Option A:** Incorrect because anorexia nervosa is indeed characterized by a distorted body image and a fear of gaining weight.
* **Option B:** Incorrect because while some individuals with anorexia nervosa may exhibit obsessive-compulsive personality traits, this is not a defining feature of the disorder.
* **Option C:** Incorrect because anorexia nervosa can occur in individuals of any age, including children and adolescents.
* **Option D:** Incorrect because while some individuals with anorexia nervosa may experience amenorrhea (loss of menstrual cycle), this is not a universal feature of the disorder.
**Clinical Pearl / High-Yield Fact**
A key feature of anorexia nervosa is the "fear of fatness," which is a deep-seated fear of gaining weight and becoming overweight. This fear is often accompanied by a distorted body image and a preoccupation with weight and body shape.
**Correct Answer: D.**
