Bulimia nervosa

Bulimia nervosa is an eating disorder involving recurring binge-and-purge eating patterns.

Individuals binge on high-calorie foods and purge through self-induced vomiting, laxative use, or engage in weight-loss behaviors like fasting or excessive exercise.

The disorder typically starts in late adolescence or early adulthood and primarily affects young women.

It causes physical complications, including chronic sore throat, esophageal damage, gastrointestinal issues, dehydration, and kidney problems. Persistent vomiting damages teeth, leading to dental erosion and cavities due to stomach acid exposure.

Individuals intensely fear weight gain, feel anxious or depressed, and struggle to control their emotions. They often hide their condition, experiencing self-disgust and shame.
