Bulimia Nervosa

Key facts

• Bulimia nervosa is an eating disorder defined by repeated cycles of binge eating followed by compensatory behaviour, self-induced vomiting, laxative use or excessive exercise, meant to undo perceived overeating.
• Body weight is often within a normal range, unlike anorexia, so the condition can go unrecognised for years.
• Cognitive behavioural therapy is the most evidence-based treatment; fluoxetine, an antidepressant, is the best-studied medicine and reduces binge frequency when added to therapy.
• Speaking with a doctor or mental health professional is the right first step; crisis lines are available for anyone in immediate distress.

Recognising the pattern

The core feature is a loss-of-control feeling during eating episodes, followed by guilt and a strong urge to compensate. Physical signs include tooth enamel erosion, swollen cheek glands and knuckle calluses. Mood shifts, secrecy around food, and frequent trips to the bathroom after meals are common behavioural signs. Social pressure around body image and food can make the condition especially likely to go unreported, which lets it persist quietly for years.

How it is managed

Cognitive behavioural therapy is the most evidence-based treatment. Medication is often used alongside it: fluoxetine is the best-studied option and sits within the broader class of antidepressants shown to reduce binge frequency. The two approaches together tend to produce better outcomes than either alone.

Getting help

If you or someone close to you is struggling, speaking with a doctor or mental health professional is the right first step. International crisis lines offer immediate support for anyone in distress, and a doctor can arrange a referral to structured eating-disorder treatment. Recovery is often gradual, and relapse during treatment is common; it does not mean therapy has failed.
