Anorexia nervosa is an eating disorder characterized by an intense fear of gaining weight, refusal to maintain a healthy body weight, and a distorted body image. People with anorexia often excessively exercise and restrict food intake, and some may purge through vomiting or laxative abuse. Symptoms include weight loss, fear of gaining weight, and denial of hunger. The causes are unclear but involve biological, psychological, and social factors. Treatment involves medical care if needed, psychotherapy, nutrition counseling, and sometimes medication to address underlying mental health issues and restore healthy eating patterns.
