Anorexia Nervosa

Evidence-informed definition Updated June 1, 2026 How to cite this entry

Anorexia nervosa is an eating disorder characterized by self-imposed restriction of energy intake, leading to a significantly low body weight. Individuals with anorexia have an intense fear of gaining weight and exhibit a distorted perception of body image, often failing to recognize the severity of their low weight. This disorder can result in serious physical and psychological health complications, requiring a multidisciplinary approach to treatment, including nutritional support and psychotherapy.
