Dysorexia is any eating disorder — the umbrella medical term for disturbed eating patterns. It covers anorexia nervosa, bulimia nervosa, binge-eating disorder, and the atypical forms that meet most but not all diagnostic criteria. The common thread is a pathological relationship with food, weight, and body image that damages physical health — malnutrition, electrolyte chaos, bone loss, cardiac risk — and dominates mental life. Treatment is multidisciplinary: medical stabilisation, nutritional rehabilitation to restore healthy eating patterns, and psychological therapy addressing the beliefs that drive the disorder. Dietitians play a central role, rebuilding a normal relationship with food meal by meal. The term itself is clinical shorthand; the conditions it names are among the most dangerous in psychiatry, with anorexia carrying the highest mortality of any mental illness.
