🎧MSRA PODCAST:Non-Alcoholic Fatty Liver Disease (NAFLD) – A Silent Epidemic🩺 A complete, high-yield review of NAFLD – the mostcommon liver disease in the developed world. From definition to diagnosis,differentials to complications – this is your go-to audio revision for theMSRA. 🧠Key Learning Points📌Definition• NAFLD = fat accumulation in the liver withoutsignificant alcohol intake• A spectrum: – Simple steatosis → fat only – NASH (Non-Alcoholic Steatohepatitis) → fat +inflammation ± fibrosis🧠Mnemonic: “NAFLD is fatty liver without the booze” 📌Causes & RiskFactors• Closely linked to Metabolic Syndrome: – Obesity – Type 2 diabetes – Insulin resistance – Hypertension – Dyslipidaemia• Other riskfactors: – Rapid weight loss – PCOS – Certainmedications – Older age andgenetic predisposition🧠Memory aid: OMG = Older age, Metabolic syndrome, Genetics 📌Pathophysiology• Excess fat (mostlytriglycerides) builds up in hepatocytes• Driven by insulin resistance, mitochondrial dysfunction,and increased fatty acid delivery to the liver🧠Too much in, notenough out 📌DifferentialDiagnosis• Must rule out other liver conditions: – Alcoholic liverdisease – Viral hepatitis(A, B, C, E) – Haemochromatosis,Wilson’s disease – Autoimmunehepatitis, PBC, PSC – Medications,thyroid disease, alpha-1 antitrypsin deficiency 📌Epidemiology• UK prevalence ~ 20–30% of adults• NASH ~ 5% in Europe• Up to 94% in obese populations• Leading cause ofabnormal LFTs in developed countries 📌Clinical Features• Often asymptomatic• If present: – Fatigue – Right upperquadrant discomfort – Hepatomegaly• Late complications: – Cirrhosis – Portalhypertension – Hepatocellularcarcinoma (HCC)🧠ALT ↑ early, but canfall with worsening disease 📌Diagnosis &Investigations✅LFTs – ALT > AST (early)✅Ultrasound – bright liver (↑ echogenicity)✅ELF, FIB-4, NAFLD Fibrosis Score – estimate fibrosis risk✅Fibroscan – liver stiffness✅Liver biopsy – gold standard (for NASH/fibrosis staging)🧠Normal LFTs ≠ normalliver 📌ManagementLifestyle is key:✔️Weight loss (5–10% of body weight)✔️Mediterranean diet✔️Regular exercise❌ Avoid alcohol❌ No crash diets💊 No drugs currently licensed in the UK specificallyfor NASH🧠Everything hinges onlifestyle modification 📌Complications• NASH → Fibrosis→ Cirrhosis → Liver cancer• ↑ risk of Cardiovascular disease (leading cause of deathin NAFLD patients)🧠Not always harmless– monitor and refer high-risk patients 📎NAFLD MSRA Resources📝Revision Notes:https://www.passthemsra.com/topic/non-alcoholic-fatty-liver-disease-revision-notes/🧠Flashcards:https://www.passthemsra.com/topic/non-alcoholic-fatty-liver-disease-flashcards/💬Accordion Q&ANotes:https://www.passthemsra.com/topic/non-alcoholic-fatty-liver-disease-accordion-qa-notes/🚀Rapid Fire Quiz:https://www.passthemsra.com/topic/non-alcoholic-fatty-liver-disease-rapid-quiz/🎓Gastro Course Home:https://www.passthemsra.com/courses/gastroenterology-for-the-msra/ Hashtags#MSRA #NAFLD #NASH#FattyLiver #MetabolicSyndrome #MSRARevision #GastroMSRA #MSRAFlashcards#LiverHealth #MSRAQuiz #NICEGuidelines #MSRAOnlineRevision#NonAlcoholicFattyLiverDisease
