Self-worth is heavily tied to body weight and shape.📌 Causes & Risk Factors🧬 Multifactorial:• Genetic predisposition• Psychological traits (perfectionism, low self-esteem)• Environmental and societal pressures (thin ideal)⚠️ Risk Factors:• Female sex (3:1 female to male ratio)• Age 15–25 (median ~20)• Family history of EDs or mental health disorders• History of trauma or abuse• Early menarche, dieting, parental obesity• Psychiatric comorbidities (anxiety, depression)📌 Pathophysiology• Psychological drive = fear of weight gain + distorted body image• Neurobiology: serotonin and appetite-regulating pathways disrupted• Feedback loop of binge-purge linked to emotional dysregulation📌 Symptoms & Signs• Binge eating with loss of control• Self-induced vomiting, laxative misuse• Preoccupation with body shape• Dental erosion, swollen salivary glands, Russell’s sign (knuckle calluses)• GI issues, amenorrhea, arrhythmias due to electrolyte imbalance📌 Differential Diagnosis🔍• Anorexia nervosa (BMI <17.5)• Binge eating disorder (no purging)• GI causes of vomiting• Substance abuse• Psychiatric conditions (e.g. OCD, depression)📌 Investigations• Diagnosis = clinical, based on history & behaviours🧪 Key tests:• U&Es (esp. potassium)• LFTs, magnesium, phosphate• FBC, iron studies• ECG (arrhythmia risk)• Pregnancy test, DXA scan (if amenorrhoea)📌 Management👥 Multidisciplinary approach• 📘 CBT-ED = first-line• 🥗 Nutritional rehab• 💊 SSRIs (e.g. fluoxetine) – adjunct to therapy• 🦷 Dental support• ⚠️ Monitor electrolytes, fluids, comorbidities🧠 For under 18s → family therapy or individual CBT-ED📌 Complications• Hypokalaemia → arrhythmias• Dehydration, metabolic alkalosis• Dental and GI damage (e.g. oesophagitis)• Osteoporosis (long-term)• Mental health risks: depression, self-harm, substance misuse• 💔 Social impact, impaired functioning📌 Prognosis• 80% achieve recovery with treatment• Higher recovery rates than anorexia nervosa• Early recognition improves outcomes⚠️ Relapse is common → ongoing follow-up essential📎 Useful Resources for Bulimia Nervosa (MSRA)📝 Revision Notes:https://www.passthemsra.com/topic/bulimia-nervosa-revision-notes/🧠 Flashcards:https://www.passthemsra.com/topic/bulimia-nervosa-flashcards/💬 Accordion Q&A Notes:https://www.passthemsra.com/topic/bulimia-nervosa-accordion-qa-notes/🚀 Rapid Quiz:https://www.passthemsra.com/topic/bulimia-nervosa-rapid-quiz/🎓 Full Psychiatry Course:https://www.passthemsra.com/courses/psychiatry-for-the-msra/🧪 Quizzes Page:https://www.passthemsra.com/quizzes/bulimia-nervosa/#MSRA #BulimiaNervosa #PsychiatryMSRA #MSRARevision #MSRAFlashcards #MSRAQuestionBank #MSRATextbook #PassTheMSRA #CBT #EatingDisorders
