**Core Concept**
Anorexia nervosa is a psychiatric disorder characterized by a distorted body image and an intense fear of gaining weight, leading to restrictive eating habits and significant weight loss. The symptoms of anorexia nervosa are multifaceted, involving psychological, physiological, and behavioral aspects.
**Why the Correct Answer is Right**
The symptoms of anorexia nervosa typically include excessive weight loss, amenorrhea, bradycardia, and osteoporosis. These symptoms are a result of the body's adaptation to starvation, including decreased leptin levels, increased ghrelin levels, and altered hypothalamic-pituitary-adrenal (HPA) axis function. The HPA axis dysfunction leads to decreased cortisol levels, which in turn causes osteoporosis, bradycardia, and other metabolic changes.
