Anorexia Nervosa (AN) is a serious eating disorder characterized by persistent restriction of energy intake, intense fear of gaining weight, and a distorted perception of body image. Individuals with anorexia often experience a relentless pursuit of thinness and significant distress about weight or shape, even when underweight. This condition can lead to severe medical complications, including electrolyte imbalance, cardiac abnormalities, bone density loss, and multi-organ dysfunction. Treatment focuses on medical stabilization, weight restoration, nutritional rehabilitation, and addressing cognitive and emotional factors underlying restrictive eating and body image disturbance.
