## Quick answer

What are eating disorders? Eating disorders are serious mental health conditions involving disturbed eating behaviours and distress about weight or shape — including anorexia (severe restriction), bulimia (binge-purge cycles), and binge eating disorder. They affect all ages and genders — not a choice or vanity. Physical complications include heart problems, osteoporosis, and electrolyte imbalance — can be fatal. GP referral to specialist eating disorder services — early treatment improves recovery. Seek urgent help for collapse, chest pain, or suicidal thoughts.

## ! When to see a GP about eating disorders

See a GP if you or someone you care about restricts food severely, vomits after meals, uses laxatives for weight control, binges regularly with distress, or is preoccupied with weight to the point of avoiding social eating. Urgent same-day if dizziness, chest pain, palpitations, fainting, blood in vomit, or suicidal ideation. Eating disorders need medical assessment of weight, bloods, and ECG — not diet advice alone.

## Common questions about eating disorders

What are the signs of anorexia nervosa? Severe food restriction, low body weight or failure to gain expected weight in adolescents, intense fear of gaining weight, distorted body image, missing periods in women, excessive exercise, hiding food. Physical signs — dizziness, cold intolerance, fine body hair (lanugo), slow heart rate. What is bulimia nervosa? Recurrent binge eating — large amounts with sense of loss of control — followed by compensatory behaviours — self-induced vomiting, laxative misuse, fasting, or over-exercise. Weight may be normal — hidden condition common. Russell sign — knuckle calluses from vomiting. How are eating disorders treated on the NHS? Specialist eating disorder teams — medical monitoring, dietetic support, CBT-E (enhanced CBT for eating disorders), family-based treatment for adolescents with anorexia, guided self-help for binge eating disorder. Hospital or day patient admission if medically unstable — very low weight, abnormal bloods, suicide risk. Can you recover from an eating disorder? Yes — full recovery possible though takes time — relapses can occur during stress. Early specialist treatment improves prognosis. Anorexia recovery often 1 to 5+ years — patience and multidisciplinary support essential. What physical complications can eating disorders cause? Heart arrhythmias and sudden death (electrolytes from vomiting), osteoporosis, fertility problems, dental erosion (bulimia), refeeding syndrome if renourishment too fast in severe malnutrition — requires medical supervision.
