Snapshot A 22-year-old woman presents to her university health center for a primary care appointment. She admits that she thinks she is "fat" and feels extremely self-conscious about her body. She describes having various periods of strict dieting interspersed with days when she binges on candy bars and dessert foods. She says that she would keep the candy bars and desserts hidden in her closet and eat them late at night when her roommates would not be able to observe her. She notes that although she feels some relief immediately after a binge, she feels extremely distressed afterwards and has started making herself throw up. She is engaging in binge-purge episodes about 5 to 6 times per week. Her BMI is 21 kg/m2.
