Anorexia, or anorexia nervosa, is a serious eating disorder characterized by an intense fear of gaining weight and a distorted body image. Individuals with anorexia often restrict their food intake, leading to significant weight loss and malnutrition. This condition can affect anyone but is most commonly seen in adolescents and young adults. The causes of anorexia are complex and can include genetic, environmental, and psychological factors. Treatment typically involves a combination of medical care, nutritional counseling, and therapy to address the underlying issues and promote healthy eating habits. Early intervention is crucial for recovery.
