Endo: Type 1 Diabetes Mellitus: Free MSRA Podcast

🧠FREE MSRA PODCAST –Type 1 Diabetes Mellitus: Diagnosis, DKA & Daily Insulin Mastery🎧 In this essential episode, we break down Type 1 Diabetes Mellitus (T1DM) — a core MSRA topic — covering its autoimmune roots, classic presentation, and life-saving managementstrategies including insulin regimens, NICE guidance, and complicationprevention. 🧠Key Learning Points📌Definition• T1DM is an autoimmune condition that destroys pancreatic beta cells, causing absolute insulin deficiency• Without insulin,glucose cannot enter cells → hyperglycaemia+ ketone formation• Usually presentsin childhood or adolescence, but canoccur at any age 📌Mnemonics• 🔑 "Polys + Weight Loss +Fatigue" = Classic triad• 🎯 "Genes load the gun,environment pulls the trigger" =Autoimmune pathogenesis 📌Causes & RiskFactors• 🔬 Genetic predisposition – especially HLA-DR3 & DR4• 🦠 Environmental triggers – viral infections (e.g. enteroviruses)• 🧬 Autoimmune link – coeliac, thyroiditis, Addison’s• 📈 Family history (parent or sibling with T1DM) 📌Symptoms• Polyuria (frequent urination)• Polydipsia (increased thirst)• Polyphagia (increased hunger)• Weight loss, fatigue,blurred vision• 🎯 Red flag: DKA → abdo pain, Kussmaul breathing, acetone breath 📌Investigations🧪Urine dipstick – glucose + ketones🧪Blood glucose: • Fasting ≥7.0mmol/L • Random ≥11.1mmol/L🧪C-peptide – LOW in T1DM🧪Autoantibodies: • Anti-GAD (80%),IA2, ICA, IAA (younger kids)🩸 HbA1c: ≥48 mmol/mol = diagnostic if stable 📌Differentials• T2DM – morecommon, gradual onset• LADA – slowerautoimmune diabetes in adults• Secondary diabetes– pancreatitis, steroids 📌Management💉Insulin therapy islifelong and essential • Basal-bolus regimen OR • Insulin pump (CSII)📱Continuous GlucoseMonitoring (CGM) now NICE recommendedfor all🥦Diet + Exercise – tailored advice from specialist team🚭 Smoking cessation, travel planning, and DVLAnotification for drivers📊 Regular glucose monitoring and annual reviews 📌ComplicationsAcute• ⚠️ DKA –life-threatening• ⚠️ Hypoglycaemia– from insulin or missed mealsChronic• 👁 Diabetic retinopathy• 💓 Cardiovascular disease• 💉 Nephropathy → renal failure• ⚡Neuropathy → foot ulcers, infections, amputation• 🦶 Diabetic foot complications• 🦠 Immunosuppression – increased infection risk 📌Prognosis• 👍 With modern CGMs, insulin types, support, and tight glycaemiccontrol, people canlive long and healthy lives• ⚠️Poor control = ↑ risk of blindness, dialysis, amputations, stroke• 💡 Early diagnosis + tailored treatment = key to long-term outcomes 📎More MSRA Resourcesfor Type 1 Diabetes Mellitus📝 Revision Notes:https://www.passthemsra.com/topic/diabetes-mellitus-type-1-revision-notes/🧠 Flashcards:https://www.passthemsra.com/topic/diabetes-mellitus-type-1-flashcards/💬 Accordion Q&A Notes:https://www.passthemsra.com/topic/diabetes-mellitus-type-1-accordion-qa-notes/🚀 Rapid Quiz:https://www.passthemsra.com/topic/diabetes-mellitus-type-1-rapid-quiz/🎓 Full Course – Endocrinology for the MSRA:https://www.passthemsra.com/courses/gastroenterology-for-the-msra/ Hashtags#MSRA #MSRARevision#Type1DiabetesMSRA #MSRAFlashcards #EndocrinologyMSRA #DKA #InsulinTherapy#NICEGuidelines #MSRAExam #MedicalEducation #MSRAOnlineRevision#MultiSpecialityRecruitmentAssessment
