Performance medicine, in plain terms
“Performance doctor” is not a formal medical specialty. The recognised specialty is Sport and Exercise Medicine, and the title is used more loosely, so it helps to know what good practice looks like rather than relying on the label.
At its best, the work sits across several areas at once: cardiovascular and metabolic health, hormones, sleep, recovery, body composition and the demands of training or work. A performance doctor reads these together and explains how they connect to how you feel and what you ask of your body.
You do not need to be an athlete. The same thinking applies to a founder with a punishing diary as much as to a rugby player.
What a good performance doctor should do
- Listen first. Your history, medicines, training, sleep and work pressures come before any test is chosen.
- Choose investigations for a reason, not from a menu.
- Read results together, so a single flagged value is weighed against everything else.
- Put the plan in writing, with clear priorities.
- Follow up, so the plan is checked against how you actually respond.
- Say plainly when something falls outside their remit, and advise GP review or urgent assessment where it does.
That last point matters. A good performance doctor works alongside NHS care and does not stand in for it.
How Dr George works at Prosper
Dr George is a GMC-registered doctor whose qualifications are BSc(Hons) MBChB PGDipSEM DipFSEM. His grounding is in Emergency Medicine, he works as an Immediate Care Doctor in professional rugby, he teaches for Apex Longevity Academy and he is completing an MSc in Sports and Exercise Medicine at the University of Bath. More is on the about page.
The flagship programme is Prosper Clarity. It begins with a comprehensive blood panel through a partner laboratory, taken by a phlebotomist at home. Dr George prepares a review of your results before you speak, then holds a 60-minute consultation. You receive a detailed written report and a personalised action plan, and a 45-minute follow-up checks how things have gone. The full sequence is on the how it works page.
When it is worth seeing one
People tend to come when energy, recovery or performance has changed and they want to understand it properly, or when they want a clear baseline while nothing is wrong. Both are reasonable starting points.
Anything acute or worrying belongs with your GP or NHS 111 first. A performance doctor is for considered, planned health work, not for emergencies.
What a performance doctor is not
It is not emergency or urgent care, and it does not replace your GP. If a result needs attention, Dr George will tell you plainly and advise GP review or urgent assessment as appropriate. Nobody can promise a particular outcome, and Prosper does not. Any discussion of prescribing requires a separate formal consultation.
