Beth, aged 18, has been trying to keep a secret from her family and friends. She is a binge eater. When others are not around, she gorges on cakes, ice cream and other food so fast that she hardly has time to chew. Once she begins there is no stopping until her stomach aches. After her binge, Beth feels disgusted with herself and makes herself vomit, then takes a double dose of laxative. Her life is totally dominated by her obsession with food. Beth is suffering from which disorder?

Bulimia Nervosa

The correct answer is Option (3) → Bulimia Nervosa

Bulimia Nervosa is characterized by episodes of binge eating, followed by compensatory behaviors to prevent weight gain, such as vomiting or using laxatives. Beth's behavior of gorging on food quickly, feeling disgusted afterward, and engaging in purging (vomiting and laxative use) aligns with the symptoms of Bulimia Nervosa.
