Eating disorders are mental illnesses measured in recovery odds
An eating disorder is a mental illness marked by harmful eating patterns and body-image distress—restricting, bingeing, purging, or related behaviors. In wealthy countries, anorexia hits about 0.4% and bulimia about 1.3% of young women yearly; binge-eating disorder affects roughly 1.6% of women and 0.8% of men. Many recover with care.
ICD-10 and DSM-5 list anorexia nervosa, bulimia nervosa, binge-eating disorder, and related conditions as mental disorders. Anorexia pairs energy restriction and significantly low weight with intense fear of fatness and distorted body appraisal; subtypes restrict or binge-purge. DSM-5 dropped amenorrhea as required, recognizing males and others who do not menstruate. Bulimia features recurrent binges plus compensatory vomiting, laxatives, exercise, or fasting while weight stays at or above a minimal normal level; severity tracks weekly compensatory episodes.
Causes remain unclear; biology and environment both matter. Thinness ideals and sexual-abuse histories raise risk; pica and rumination appear more often with intellectual disability. Treatment may combine counseling, nutrition guidance, exercise reduction, and medicines for related symptoms; hospitals manage dangerous cases. Roughly seventy percent with anorexia and half with bulimia recover within five years, though only about ten percent of people with anorexia receive treatment in some analyses.
Prevalence estimates swing with gender, age, culture, and methods. Classification does not: these are specified mental disorders, not lifestyles or willpower failures. Evidence-based support changes trajectories; stigma and delayed help still cost years.
Beyond the best-known three, the manuals recognise several less familiar diagnoses. Binge-eating disorder involves repeated binges, eaten fast and past comfortable fullness, but without the vomiting or fasting that follow in bulimia. Pica is the persistent eating of things that are not food, most often paper, soap, hair, chalk, paint or clay. Rumination disorder means bringing food back up to rechew, reswallow or spit out, over at least a month. ARFID covers avoidance driven by disinterest, texture or fear of consequences that leaves nutritional needs unmet. Outside the formal lists sit labels such as diabulimia, where people with diabetes manipulate insulin to control weight, and night eating syndrome, marked by taking in a quarter or more of daily calories after the evening meal.
