Which physical finding is commonly associated with anorexia nervosa?

Dry skin is indeed a commonly associated physical finding in individuals with anorexia nervosa. This condition often leads to significant nutritional deficiencies and dehydration, which can contribute to the skin's appearance. Since patients typically consume fewer calories and may lack essential fatty acids, vitamins, and minerals, the skin may lose its natural moisture and elasticity, resulting in a dry and potentially scaly texture.

In anorexia nervosa, the body's overall stress response and low energy availability can further impair skin health, as the body prioritizes vital organ function over peripheral tissues. Because the skin is one of the body's largest organs, it is sensitive to changes in nutrition and hydration, making it a visible indicator of the physiological effects of the disorder.

Other physical findings such as brittle nails and hair loss can also occur but are more often linked to long-term malnutrition and are not as directly associated as dry skin. Swollen lymph nodes may occur in other conditions but are not typically a direct result of anorexia nervosa. Understanding these effects is crucial for recognizing the signs of anorexia and facilitating appropriate interventions.
