Haem: Folic Acid Deficiency: Free MSRA Podcast

🎙️MSRA Podcast: FolicAcid Deficiency – The B9 Breakdown You’ll Remember! 🎙️Join us as we cutthrough the confusion and get crystal clear on folicacid deficiency—the essential B vitamin you really can’t ignore, especially in pregnancy, chronic disease,and rapid growth. Here’s your quick, punchy, and memorable revision hit! 🗝️ Key Learning PointsDefinitionFolic acid (Vitamin B9) deficiency means low levels of folate, which is vital for DNA synthesis, healthy red blood cell production, and nervous system health.Most important consequence? Megaloblastic (macrocytic) anaemia and neural tube defects in pregnancy.Sources & Memory TipColorful foods: leafy greens, broccoli, beans, peas, brown rice, fortified cereals, oranges, bananas.Memory aid: Think “FOLIAGE for FOLATE”.Causes (Mnemonic: DAMN)Diet: Poor intake, unbalanced diet, alcoholism.Absorption: Malabsorption (e.g. coeliac disease, Crohn’s), GI surgery.Medications: Anti-folates (methotrexate, trimethoprim), phenytoin.Need: Increased demand (pregnancy, rapid growth, cancer, haemolytic anaemia).At-Risk GroupsPregnant women (increased needs)Older adults, alcoholicsPeople with GI disorders or on chronic anti-folate medsPathophysiologyFolate = DNA factory fuel: Deficiency disrupts cell division—especially in the bone marrow, leading to big, fragile red cells (megaloblastic anaemia).Also raises homocysteine (↑ cardiovascular risk) and impairs fetal neural tube development.Symptoms (Mnemonic: FATIGUE)Fatigue, Anaemia, Tongue (glossitis), Irritability, Gut (mild GI upset), Unwell (general), Easy breathlessness/pallorInvestigationsFull blood count (FBC): Macrocytic anaemiaBlood film: Macrocytes, hypersegmented neutrophilsSerum folate & B12 levels (always check both!)Red cell folate: Best for long-term statusAdditional: Underlying cause work-up (coeliac screen, LFTs, TFTs)Key DifferentialVitamin B12 deficiency (ALWAYS exclude this before treating with folic acid alone to avoid irreversible neurological damage)ManagementOral folic acid: 5mg daily for 4 months (higher if malabsorption)Address underlying cause: e.g. treat coeliac disease, diet improvement, alcohol supportPrevention:400 micrograms daily for all women planning pregnancy and during the first 12 weeks5mg daily if high risk (previous NTD, diabetes, anti-epileptics)Diet advice: more leafy greens, beans, fortified cerealsComplicationsUntreated: Severe anaemia, heart failure, mild neuropathy, ↑ infection riskPregnancy: Neural tube defects (e.g. spina bifida) if not supplementedPrognosisExcellent if recognised and treated early. Most symptoms resolve; complications preventable. 📚 MSRA Revision ResourcesRevision Notes:https://www.passthemsra.com/topic/folic-acid-deficiency-revision-notes/Flashcards:https://www.passthemsra.com/topic/folic-acid-deficiency-flashcards/Accordion Q&A:https://www.passthemsra.com/topic/folic-acid-deficiency-accordion-qa-notes/Rapid Quiz:https://www.passthemsra.com/topic/folic-acid-deficiency-rapid-quiz/Online Quiz:https://www.passthemsra.com/quizzes/folic-acid-deficiency/ #MSRA#FolicAcidDeficiency #B9 #Haematology #MSRARevision #PassTheMSRA#MedicalEducation #MegaloblasticAnaemia #PregnancyCare #NeuralTubeDefects#MedStudent #MedPodcast Revision Pearl:Always check B12 before giving folic acid—never maska B12 deficiency!
