Georgia Kaplan is a 22-year-old college student with anorexia nervosa. She was diagnosed when she was 15 years old while attending boarding school. She has undergone intensive treatment with recent better control of her disorder. At present she weighs 98 pounds and her height is 5 feet 2 inches. She is fearful of gaining weight.

Her roommate shop, cook, and share meals with each other, but Georgia prefers to by herself.

Georgia exercises twice a day. In the morning she jogs with on of her roommates. In the afternoon she works out, concentrating on her abdomen, which she believes is “too fat and sticks out too much.” She has not had a menstrual period in more than 3 months. Before that time, her menstrual cycle was irregular and fluctuated with the control of her disease.

On physical examination, Georgia appears pale and thin. Her temperature is 96.2 degrees, her blood pressure is 64/42, and her pulse is 58 and regular. She states that she has occasional dizziness but, as long as she changes her position slowly from lying to sitting, this dizziness is not usually bothersome.
