Which physical examination finding is commonly associated with anorexia nervosa?

Emaciation is a key physical examination finding associated with anorexia nervosa due to the significant weight loss and malnutrition that characterize the disorder. Individuals with anorexia nervosa often engage in extreme dietary restriction, excessive exercise, and may develop a distorted body image, leading to an accumulation of severe caloric deficit.

This condition manifests in the body through notable physical signs, one of the most prominent being emaciation, which involves extreme thinness or a very low body weight. Emaciation reflects the grave consequences of inadequate nutritional intake and can lead to numerous other health complications, including cardiovascular issues, electrolyte imbalances, and weakened immune function.

In contrast, hypertension is typically not associated with anorexia nervosa; individuals may actually experience hypotension due to dehydration and malnutrition. Bradypnea is generally not a direct consequence of anorexia but can occur due to metabolic disturbances. Hyperthermia is more related to infections or heat-related illnesses rather than anorexia nervosa, where individuals may exhibit lower body temperature due to substantial weight loss and reduced metabolic activity.
