Gastro: Cyclical Vomiting Syndrome: Free MSRA Podcast

⚕️ FREE MSRA PODCAST – CyclicalVomiting Syndrome🎧 A clear, high-yield breakdown of this episodic vomiting disorder with migraine links – perfect for exam prep and real-life clinicalscenarios. 🧠 Key Learning Points📌 Definition•Cyclical Vomiting Syndrome (CVS) is a rare condition defined by recurrent, stereotypical episodes of intense nauseaand vomiting, separated by completely symptom-freeintervals.📌 Causes & Risk Factors•Exact cause unknown – believed to involve:Autonomic nervous system dysregulationNeurotransmitter imbalances (esp. serotonin)Genetic predisposition• Triggers may include: stress, infections, sleep deprivation, certain foods (e.g. chocolate, cheese), menstruationMnemonic: “M’s for CVS” – Migraines (family/personal), Mood (anxiety/depression), Motion sickness📌 Pathophysiology•Dysfunctional autonomic signals + abnormal serotonin signalling → triggervomiting episodes•Often shares mechanisms with migraine pathways•May involve central brain-gut communicationdisruption📌 Symptoms•Intense, repeated vomiting during episodes (e.g. 4+ times/hour)•Severe nausea, pallor, sweating,abdominal pain•Headache, photophobia, dizziness,diarrhoea possible•Stereotypical pattern:Prodrome: nausea, sweating, pallorVomiting phaseRecoveryWell phase (normal between episodes)Mnemonic: “4 Phases = PVRW – Prodrome, Vomiting, Recovery, Well”📌 Differential Diagnosis•GI: GERD, IBD, obstruction•Neuro: Migraine-associated vomiting•Metabolic: DKA, Addison’s•Psycho: Functional vomiting, anxiety•Endocrine: Thyroid, adrenal•Substance-related: Cannabinoidhyperemesis syndromeMnemonic: “GiveNew Meds Plus Extra Support” (GI, Neuro, Metabolic, Psych, Endocrine,Substance)📌 Diagnosis•Clinical pattern: ≥3 stereotypical episodes/yearwith symptom-free intervals•Use Rome IV criteria (adjusted forchildren vs adults)•Rule out other causes:Bloods, pregnancy test, metabolic screenConsider GI/endocrine/neuro causes • No specific test confirms CVS📌 Management•Identify and avoid triggersStress reduction, adequate sleep, regular meals, hydration • Preventive/prophylactic meds:Amitriptyline, propranolol, topiramate • Abortive meds during an episode:Antiemetics (ondansetron, prochlorperazine)Triptans (if migraine-associated) • Supportive care:Fluids, pain control, restAddress comorbid anxiety or depression📌 Complications•Dehydration and electrolyte imbalance•Weight loss or growth issues in children•Dental erosion from repeated acidexposure•Social and psychological impacts – missedschool/work, anxiety📌 Prognosis•Variable course – may resolve in latechildhood•Some continue into adulthood•50% of children may later develop migraines•Good control possible with tailored management and trigger avoidance 📎 More MSRA Resources for CyclicalVomiting Syndrome📝 Revision Notes: https://www.passthemsra.com/topic/cyclical-vomiting-syndrome-revision-notes/🧠 Flashcards: https://www.passthemsra.com/topic/cyclical-vomiting-syndrome-flashcards/💬 Accordion Q&A Notes: https://www.passthemsra.com/topic/cyclical-vomiting-syndrome-accordion-qa-notes/🚀 Rapid Quiz: https://www.passthemsra.com/topic/cyclical-vomiting-syndrome-rapid-quiz/🎓 Full Course: https://www.passthemsra.com/courses/gastroenterology-for-the-msra/ Hashtags#MSRA#MSRARevision #MSRATextbook #MSRAQuiz #MSRAQuestionBank #MSRAFlashcards#MSRAQandANotes #MSRAAccordions #MultiSpecialtyRecruitmentAssessment#MSRAOnlineRevision #MSRARevisionWebsite #CyclicalVomitingSyndrome
