Your Annual Medical: Does It Tell You How Healthy You Are?
You book the annual medical. Blood tests, blood pressure, an ECG, weight and a discussion about family history. The results tell you nothing significant has been found. Your cholesterol is acceptable, your glucose is within range and your blood pressure looked fine on the day.
You breathe a sigh of relief, close the report and put another reminder in the diary for next year.
If that sounds familiar, here is the question I want you to ask: did your medical establish how healthy you are, or did it establish that you do not currently have an obvious diagnosis?
There is a considerable difference.
What was your medical designed to find?
Traditional health checks, including private annual medicals, are primarily built around identifying disease and established risk factors. The NHS Health Check, for example, assesses risk of heart disease, stroke, diabetes and kidney disease.
That is valuable. Detecting hypertension, diabetes or significant cardiovascular risk can change lives.
But as an entrepreneur or MD, I want you to know much more.
Can you move through a demanding week without your energy collapsing by Thursday? Can you stay sharp through back-to-back meetings, difficult decisions, travel and disrupted sleep? Are you still recovering well from exercise, or are you quietly relying on caffeine, adrenaline and momentum to keep going?
You can have blood tests that sit comfortably within range and still notice that your concentration is slipping, your recovery is slower, your waistline is changing, your sleep is less restorative or your energy is becoming less reliable.
These can be early signs that your physiological reserve is narrowing, long before they become a diagnosis.
There is more you can know
This is where deeper testing becomes valuable.
You can look at whether you are absorbing and using key nutrients effectively, whether your gut microbiome is supporting or disrupting metabolic and immune function, how your cortisol rhythm changes across the day, and whether your genetics reveal areas of greater vulnerability or resilience.
You can also assess glucose handling, visceral fat around your organs, cardiovascular fitness, cognitive performance for focus and attention, and biological ageing.
I recently saw an executive whose standard blood tests were broadly reassuring, yet he felt increasingly tired, mentally on edge and unable to recover from the working week as well as he used to. Looking more deeply revealed suboptimal nutrient status, a disrupted cortisol rhythm and gut findings that helped explain his energy fluctuations.
None of these amounted to a dramatic diagnosis. Together, however, they gave us a much clearer explanation for why he did not feel as healthy as his medical report suggested. And more importantly, what he could do differently.
A snapshot or a trajectory?
There is another limitation to the annual-medical mindset. Your biology does not operate annually.
Blood pressure changes across the day. Glucose can change within minutes. Sleep changes nightly. Muscle, aerobic fitness and cognitive performance can drift gradually over months and years.
One measurement tells me where you were on one particular morning. Repeated measurements tell me which direction you are travelling.
That distinction matters.
A 2019 Cochrane review of 17 randomised trials involving more than 250,000 people found that general health checks had little or no effect on overall mortality or cardiovascular mortality. The lesson here is not that health checks are pointless. The lesson is that general measurement alone does not create health.
Data only becomes useful when it changes a decision.
Not sick is not the same as healthy
Think about your business. Knowing that your company is not insolvent is important. Would you consider that sufficient evidence that the business was thriving?
Of course not.
Your health deserves the same distinction.
Have your annual medical. Use it to look for disease and risk. Then ask the bigger question:
How healthy am I, and which way am I heading?
Key takeaways
- Traditional annual medicals are designed to detect disease and risk, not to measure how well you are actually functioning as a high-performing individual.
- You can have blood test results within normal range and still experience declining energy, focus and resilience – early signs that physiological reserve is narrowing.
- Deeper testing can assess nutrient absorption, gut microbiome balance, glucose handling, visceral fat, cardiovascular fitness and cognitive performance.
- A 2019 Cochrane review of 17 trials involving more than 250,000 people found that general health checks did not reduce mortality – data only becomes useful when it changes a decision.
- The right question is not ‘am I sick?’ but ‘how healthy am I, and which way am I heading?’ – the same distinction you would apply to your business finances.
