This Podcast Will Kill You is an educational series that delves into the biology, history, and epidemiology of various diseases and medical mysteries. Hosted by Dr. Erin Welsh, a disease ecologist and epidemiologist, and Dr. Erin Allmann Updyke, a physician and epidemiologist, the podcast aims to make complex medical topics accessible and engaging for a broad audience.

Necrotic skin appearance alone cannot establish brown recluse envenomation. Geographic plausibility, witnessed exposure and expert identification matter, while fever, vomiting, jaundice or dark urine should raise concern for systemic loxoscelism, haemolysis and acute kidney injury.

Online health claims gain authority through repetition, personal stories, commercial incentives and platform algorithms rather than clinical validity. Useful consultations begin by asking what the patient saw and why it resonated, then separate symptom validation from endorsement of a diagnosis, test or product.

Raised low-density lipoprotein cholesterol is usually asymptomatic, so statin decisions depend on future cardiovascular risk rather than symptom relief. Mechanism, evidence, muscle symptoms, negative expectations, non-statin options and variable statin-like content in red yeast rice all shape balanced counselling and adherence.

Cardiology, primary-care and basic-science clinicians get a mechanism-led cholesterol review. It explains LDL, VLDL and HDL transport, atherosclerotic plaque formation, familial hypercholesterolaemia, cumulative LDL exposure and why premature cardiovascular disease in relatives should change risk assessment.

Infectious-diseases, gastroenterology and emergency clinicians get a foodborne-parasite update for prolonged watery diarrhoea. Raw berries, herbs, salad leaves, travel and shared meals guide the exposure history, while targeted stool PCR or specific microscopy, hydration assessment, co-trimoxazole treatment and public-health reporting shape management.

Obstetrics-gynaecology, fertility and safeguarding teams get an ethical and clinical discussion of IVF, egg freezing, donor conception, surrogacy and donor breast milk. It distinguishes regulated milk-bank supply from informal online purchase and keeps informed consent, commercial pressure, cross-border treatment, multiple pregnancy and the future welfare of children in view.

ENT, general-practice and emergency clinicians get a practical cerumen review. It reframes earwax as protective rather than dirty, covering lubrication, acidic antimicrobial activity, epithelial clearance, impaction, hearing aids, earbuds, cotton-swab injury, safe softening and ear-candling harm.

ENT, infectious-diseases and basic-science learners get a clinically useful review of nasal mucus, mucins, cilia, IgA, humidification and particle trapping. It turns runny nose, blocked nose, post-nasal drip, mucus colour and recurrent nose-picking into practical counselling points that help avoid unnecessary antibiotics.

A research ethics and human-factors discussion for clinicians, educators and investigators. Acute mental illness, impaired voluntariness, therapeutic misconception, authority gradients and institutional conflicts show why valid consent requires more than a signature and why unresolved participant-safety concerns may need independent escalation.

Acute-care and burns teams get a practical view of severe burns as systemic illness. Airway risk, circulation, fluid loss, infection prevention, debridement, wound cover and rehabilitation sit alongside grafts, dressings, scar prevention and long-term function.
