Psychiatry - eating disorders
Description
| Disorder | Core feature | Weight |
|---|---|---|
| Anorexia nervosa | Restriction -> significantly low weight + intense fear of weight gain + body image disturbance | Low |
| Bulimia nervosa | Binge eating + compensatory behaviour (vomiting, laxatives, exercise, fasting), >=1/week for 3 months | Normal or above |
| Binge eating disorder | Binges without compensation; the commonest eating disorder | Often overweight/obese |
| ARFID | Avoidant/restrictive intake without body image disturbance | Low or normal |
| OSFED | Subthreshold or atypical (incl. atypical anorexia - full cognitive picture at normal weight) | Any |
- Anorexia subtypes: restricting vs binge-eating/purging
- DSM-5 removed the amenorrhoea criterion and specific BMI cut-offs. Physical severity is not proportional to weight - atypical anorexia carries the same medical risk
