HPI: H.M. is a 28-year-old Caucasian female who presents with complaints of intermittent abdominal pain and bloating for the past six months. Her mother reports observing unusual eating patterns since H.M. moved back home three months ago after a breakup. H.M. attributes her recent weight gain to her job as a catering manager, where she is constantly exposed to food. Six months ago, H.M. began vomiting after eating large meals to prevent weight gain, which she continues to do at least three times a week. She also exercises rigorously, attending yoga and exercise classes six times a week. Despite being on a low-calorie diet, H.M. reports a loss of control over her eating habits and feels bad when she overeats.
