Eating disorders like anorexia and bulimia are common and involve extreme behaviors around food and weight. Anorexia involves restricting food intake and distorted body image, while bulimia involves binge eating and purging. Around 1-2% of students struggle with eating disorders, which stem from unhealthy dieting, overexercise, and underlying emotional issues. Treatments include medical care, therapy to address feelings, nutrition counseling, and social support.
