Bulimia Nervosa
Bulimia nervosa is an eating disorder marked by recurrent binge episodes followed by behaviours intended to compensate, alongside strong concern about weight or shape.
Key takeaways
- A person’s weight may appear typical, so physical appearance does not show how medically serious the disorder is.
- Vomiting, laxative misuse and dehydration can disturb potassium and heart rhythm and damage teeth, oesophagus and kidneys.
- Evidence-based psychological treatment is central; medicine may support selected symptoms but does not replace eating-disorder care.
The listings below are not a standalone treatment; medical stability, self-harm risk and coexisting mental-health conditions need assessment.
What assessment covers
Clinicians ask sensitively about binge frequency, compensatory behaviours, restriction, exercise and body-image distress. Examination and tests may include pulse, blood pressure, electrolytes, kidney function and ECG. Depression, anxiety, trauma and substance use commonly need parallel support.
Recovery-focused treatment
Structured cognitive behavioural therapy helps regularise eating and interrupt the binge–compensation cycle. Nutrition support and dental care address consequences. Fluoxetine has a specific evidence base in bulimia for some adults, but suitability and monitoring remain individual; abrupt medication changes are avoided.
When to seek urgent care
Get urgent help for fainting, chest pain, palpitations, vomiting blood, severe weakness, confusion, a seizure, inability to keep fluids down or thoughts and plans of self-harm.
