Anorexia is an 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. People with anorexia may engage in excessive exercise or other behaviors to control their weight. The disorder can have serious health consequences, including heart problems, bone density loss, and even death. Treatment typically involves a combination of medical care, nutritional counseling, and psychological support.
