Overview
Anorexia nervosa is a complex mental health condition that goes far beyond wanting to lose weight.

This disorder often involves a distorted body image, where someone sees themselves as overweight even when they're significantly underweight.
Anorexia nervosa affects approximately 0.3-1% of people worldwide. It typically develops during teenage years or early adulthood, though it can occur at any age. Women and girls are more commonly affected, but men and boys can also develop this condition. The disorder has one of the highest mortality rates of any mental health condition, making early recognition and treatment critical.

They'll ask detailed questions about eating habits, weight history, exercise patterns, and mental health symptoms. The doctor will also inquire about family history of eating disorders or other mental health conditions.
During the physical exam, the provider checks vital signs, weight, height, and looks for physical signs of malnutrition. They may examine the skin, hair, nails, and check for signs of dehydration. The evaluation also includes assessing heart rate, blood pressure, and temperature regulation.
Diagnostic Testing
Blood tests: Check for electrolyte imbalances, kidney function, liver function, and nutritional deficiencies
Electrocardiogram (EKG): Monitors heart rhythm and checks for cardiac complications from malnutrition
Bone density scan: Evaluates for osteoporosis or bone loss, which can occur with prolonged malnutrition
Psychological assessment: Structured interviews and questionnaires to evaluate mental health symptoms and eating behaviors
