Hey Doc,
Thank you for your patience. I took some time off after Cannes to recharge with my family, catch up with friends, eat Mediterranean food, discover new places and enjoy life. I am writing this week newsletter just coming back from Florence, the capital of the Renaissance. A city built by the Medici, who were essentially the original venture capitalists, backing artists, architects, and scientists the way we fund startups today. And one of those bets was Leonardo da Vinci.
Dav dissected the body of an elderly man in Florence to understand why his vessels had changed. He described thickened arterial walls, narrowed lumens, and reduced blood flow. He drew it. He documented it. Four hundred years before we had the word atherosclerosis. A painter, sitting in a morgue, doing vascular biology because he was curious.
This newsletter is my reflection on what is happening with longevity hospitality globally, and specifically the longevity tourism boom that is reshaping how people access (or think they are accessing) medicine around the world.
Each week, I try to explore one idea that could advance longevity medicine and hopefully support physicians in bringing it to life. For my full perspective.
What Is Longevity Tourism?
Longevity spa, longevity retreats, longevity checkup. Longevity is everywhere. A hotel in the Swiss Alps is selling a "longevity suite" with cryotherapy and IV drips. A resort in Bali is packaging breathwork and cold plunges as longevity medicine. A clinic in Bangkok is offering full-body MRI screenings to tourists between temple visits. A facility in the Cayman Islands is offering stem cells at $25,000 per session.
The word longevity is now a travel category.
This is not new.
People have always traveled for health. Romans soaked in the hot springs at Bath. European physicians in the 1800s prescribed entire seasons at Baden-Baden, Vichy, and Karlovy Vary. Baños de Agua Santa in Ecuador built an economy around volcanic thermal springs centuries before anyone used the word longevity. The Swiss sanatoriums treated tuberculosis with mountain air and structured rest. The Dead Sea has been a medical destination for skin disease for over two thousand years.
The instinct to travel toward health is ancient. What is new is the scale, the marketing, and the clinical distance between what is being sold and what is being supervised.
Longevity Tourism Levels: From Spa Programs to Stem Cell Clinics
Not all longevity tourism is the same. The category now spans four distinct tiers, each carrying a different risk profile.
Level 1: Hotel and spa programs. This is the entry point. A luxury hotel adds a "longevity menu" to its spa: cryotherapy, infrared saunas, IV vitamin drips, red light therapy, metabolic smoothies. The interventions are mostly low-risk. The medical supervision is mostly nonexistent.
Level 2: Retreats. A step up in duration and intention. Five to fourteen days. Structured programs with breathwork, meditation, cold exposure, movement, nutrition, and sometimes basic lab work. The best ones have medical directors and structured intake. The worst ones package the same activities under a longevity label with no clinical oversight and no follow-up after checkout.
Level 3: Diagnostic tourism. This is growing fast. Patients flying to South Korea, Thailand, or Dubai for comprehensive health screenings: full-body MRI, coronary calcium scoring, cancer biomarkers, genetic panels, gut microbiome analysis. The value proposition is real. In some of these countries, the same imaging that costs $5,000 in the United States is available for $800 with shorter wait times and newer equipment. Seoul alone has built an entire medical tourism corridor around Gangnam with clinics that process hundreds of international patients per week.
The risk is not the diagnostics themselves. The risk is what happens after. A finding on a scan means nothing without a physician who can interpret it, contextualize it, and manage the follow-up. A tourist who flies home with a USB drive full of imaging and no relationship with the radiologist who read it is not a patient. They are a consumer holding data they may not understand.
Level 4: Procedural tourism. The highest-risk tier. Stem cell injections or gene therapy in the Cayman Islands or Mexico. Exosome therapies in Dubai. Gene therapy in Costa Rica. Hyperbaric oxygen courses in Turkey. These are medical interventions being delivered outside the regulatory frameworks of the patient's home country, often by providers who could not offer the same treatments at home because of local regulations.
Benefits of Longevity Tourism: Awareness, Access, and Competition
What the boom is getting right:
Awareness. More people are willing to travel for their health. They are thinking about preventive care or health optimization because a hotel or a clinic in another country introduced the concept. That pipeline into medicine is real.
Access. A full-body MRI in Seoul for a few hundred dollars is reaching patients who would never get one at home. Diagnostic access is expanding because of tourism, not in spite of it.
Experience. Hospitality knows how to design an experience around health. Medicine historically does not. The best longevity retreats are teaching physician-led practices something about how patients want to be treated.
Competition. When a resort in Thailand offers better imaging at a third of the price, it forces domestic health systems to ask hard questions about their own pricing and access. That pressure is productive.
Risks of Longevity Tourism: No Continuity, Poor Regulation, Unproven Procedures
What the boom is getting wrong:
No continuity. A retreat lasts a week. A diagnostic trip lasts three days. A stem cell injection is a single visit. Longevity medicine is continuous. Without follow-up, without a physician who knows the patient's history, without a plan that extends beyond checkout, these are isolated events, not medicine.
Poor regulation. Many procedural tourism destinations exist precisely because the regulations are looser. That is not always sinister, but it means the patient is bearing risk that a regulatory body would normally absorb. When something goes wrong in a stem cell clinic in an offshore jurisdiction, the recourse options are limited.
Lack of science-backed protocols. Some of what is being sold at Level 3 and Level 4 has strong emerging evidence. Some of it has none. The patient often cannot tell the difference because the marketing is identical in both cases.
Inconsistent medical supervision. The spa with no medical director. The retreat with no physician on staff. The diagnostic clinic that hands you results with no consultation. The procedural facility where the "doctor" is a general practitioner who completed a weekend training in regenerative medicine. Medical supervision exists on a spectrum, and the lower end of that spectrum is lower than most patients realize.
How to Evaluate a Longevity Tourism Program: A Physician's Checklist
Whether you are a physician advising a patient or a patient evaluating a program, these are the questions that separate serious from speculative.
Is a licensed physician supervising the program? Not advising. Not consulting. Supervising. Present. Accountable. What are their credentials, their specialty training, and their experience with the specific interventions being offered?
What are the local regulations? A stem cell therapy that is illegal in the United States is not necessarily unsafe, but the patient should understand why it is not approved at home and what evidence the destination facility is relying on instead. Ask for the published data. If there is none, that is your answer.
What does the follow-up look like? Who reads your results after you leave? Who manages an incidental finding on your MRI six months later? If the answer is "your doctor at home," then the facility has built a product, not a care model.
What is the pricing telling you? A full-body MRI in Seoul for $800 reflects genuine cost efficiencies in the Korean healthcare system. A stem cell injection in the Caribbean for $25,000 reflects demand-based pricing for an unproven therapy with no insurance coverage. Price is information. Read it.
Is the facility transparent about outcomes? How many patients have they treated? What are the complication rates? What is the published evidence for the specific intervention you are considering? If the clinic cannot answer these questions with data, they are selling confidence, not medicine.
Is there a complaints or malpractice pathway? In your home country, a bad outcome has legal and regulatory recourse. In a medical tourism destination, that pathway may not exist. Understand what protections you have before you need them.
The Future of Longevity Tourism and the Role of Physicians
The longevity tourism boom is real, it is growing, and it is not going away. The instinct behind it is good. People want to live longer and better, and they are willing to travel to do it. That same instinct sent Europeans to thermal springs for three centuries.
But the distance between a spa menu and a stem cell injection is the distance between a mineral bath and surgery. The category called "longevity tourism" now contains both, and the patient browsing options on their phone cannot always tell which is which.
Physicians belong in this conversation. Not to shut it down, but to help patients navigate the spectrum with the same rigor they would bring to any clinical decision. Ask for the evidence. Ask for the credentials. Ask for the follow-up plan. Ask who is accountable when something goes wrong.
The boom is here. Let's make it as impactful as possible for the patients.
