What is a longevity doctor, and do you need one?

A longevity doctor is a physician whose main goal is to extend your healthspan, the number of years you live in good health. Most come from internal medicine, family medicine or preventive medicine, and some hold additional training in areas like cardiology, endocrinology or sports medicine.

“Longevity medicine” isn’t a separate board-certified specialty in the US. That’s why it pays to check a clinician’s underlying training and licensure, which you can look up through your state medical board.

How it differs from a standard physical

A typical annual physical is built to catch disease that’s already present. Longevity care tries to spot risk earlier and act on it sooner. In practice that usually means:

• Longer visits. Initial assessments often run 60 to 120 minutes.
• Broader testing. For example ApoB and Lp(a) for heart risk, fasting insulin for metabolic health, and sometimes imaging such as a coronary calcium scan.
• Function, not just disease. Many clinics measure cardiorespiratory fitness (VO2 max), strength and body composition, which are strong predictors of long-term health.
• An ongoing plan. Follow-up every few months to track your numbers and adjust.

Who tends to benefit

People often seek out a longevity clinic when they:

• Have a family history of heart disease, diabetes or dementia
• Feel fine but want a more detailed picture than an annual physical gives
• Have borderline lab results that haven’t been addressed
• Want structured guidance on exercise, nutrition and sleep

What to keep in mind

Many longevity practices are membership-based and not fully covered by insurance. Ask up front what’s included, what’s billed separately, and whether the clinic will coordinate with your primary care doctor. More testing isn’t always better: a good clinician explains why each test is worth doing and what they’ll do with the result.
