Karolinska MD PhD: The Hidden Phase Before Disease

Karolinska MD PhD: You Feel Healthy. Your Data DisagreesMost people think they’re healthy.But biology doesn’t care how you feel.Long before symptoms show up, your physiology is already shifting.. and most check-ups won’t catch it.In this episode, we sit down with Natalia Trpchevska (MD, PhD Karolinska, Medical & Scientific Director at AYUN) to break down what longevity medicine actually looks like when applied properly.We go beyond surface-level optimization and talk about what actually drives risk: mitochondria, metabolic flexibility, genetics, and why most people are already off track without knowing it.This episode covers:Why longevity medicine still struggles in practiceMitochondria, NAD+ and optimization mythsBiohacking and the future of healthcareKey takeaways:Health declines silently — symptoms come lateLongevity medicine asks: where are you heading biologically?The basics still dominate outcomes — most people underestimate themThe next level is personalization, not more hacksTwo “healthy” people can have completely different risksMitochondria adapt first — then they start driving dysfunctionMost mitochondrial interventions are misunderstoodGenetics gives probabilities, not certaintyReal optimization = prioritization + sequencingAbout Natalia:Natalia Trpchevska is a medical doctor and holds a PhD in genetics from the Karolinska Institutet.She is the Medical & Scientific Director at AYUN in Zurich, where she focuses on applying systems biology and layered diagnostics to detect early shifts in physiology — before disease develops.Her work bridges clinical medicine and research, with a strong emphasis on translating complex biology into actionable interventions.Timestamps:00:00 – Introduction & Natalia’s background (Karolinska, genetics → clinic)03:30 – Why genetics naturally leads into longevity medicine05:00 – What longevity medicine actually does differently07:30 – “Physiology before pathology” explained09:30 – The basics vs. the real next level11:30 – Same lifestyle, completely different risk profiles13:30 – APOE4, Lp(a) and personalized strategy15:00 – Mitochondria: what actually happens as you age18:30 – When mitochondrial dysfunction becomes clinically relevant21:00 – Cause vs. consequence: where mitochondria fit in aging23:30 – How mitochondrial function is actually measured26:30 – Why isolated tests don’t work (layered diagnostics)29:00 – What happens after testing: prioritization & sequencing32:00 – Why “doing everything” doesn’t work35:00 – IHHT explained: mechanism, benefits, limitations38:30 – Risks, contraindications & when it backfires41:00 – Environment vs. lifestyle: what really drives dysfunction44:00 – The hierarchy: metabolism → inflammation → toxins47:00 – Why most people focus on the wrong layer49:30 – What genetics got wrong over the last decade53:00 – Polygenic risk, probabilities & real-world use56:00 – Gene–environment interaction: what actually matters58:30 – Final thoughts: what people still misunderstand about healthLinks:Natalia:https://www.linkedin.com/in/natalia-trpchevska/https://www.ayun.ch/More about Return on Health:https://returnonhealth.de/Niko:https://www.linkedin.com/in/niko-hems/https://www.instagram.com/niko_hemshttps://nikohems.de/Miguel:https://www.linkedin.com/in/miguel-medina-stanivukovic-857b9720b/https://www.instagram.com/miguelmedinastanivukovic/
