The Myth of "If It's Not Broken"
Most people don't see a doctor unless something is wrong. That logic works fine for acute problems — a broken bone, an infection, a sudden chest pain. It fails completely for the conditions that actually kill most people: cardiovascular disease, type 2 diabetes, kidney disease, cancer, and metabolic syndrome.
These conditions don't announce themselves. They develop over years or decades, silently progressing through stages where intervention is cheap and effective, until they reach a stage where it's expensive, difficult, or too late. A raised LDL cholesterol at 42 doesn't cause symptoms — but it's been silently building arterial plaque for years. A fasting glucose of 6.4 doesn't feel different from 5.0 — but it's prediabetes, and without intervention it commonly progresses to diabetes within five years.
Preventative health checks exist to catch these problems in their silent phase. That's where the real value lies.
What NHS Screening Covers — and What It Misses
The NHS does offer some preventative screening: the NHS Health Check for 40–74 year olds (offered every five years), bowel and cervical cancer screening programs, and breast and aortic aneurysm screening in specific age groups. These programs are valuable and save lives.
But they have significant gaps:
- The NHS Health Check covers a limited set of markers and is offered only every five years — a long time between assessments for someone with risk factors
- Many important markers — ferritin, vitamin D, thyroid function, hormone levels, full lipid subfractions, HbA1c before the diabetic range — are not routinely included
- Appointments are brief, limiting the depth of discussion about results and their implications
- There's no personalisation based on family history, symptoms, or individual risk profile
A private health check fills these gaps. It's not about duplicating what the NHS does — it's about going deeper where the NHS doesn't go, and going more often where the NHS goes rarely.
What a Comprehensive Health Check Covers
Cardiovascular Risk
Full lipid panel (total cholesterol, LDL, HDL, triglycerides, LDL:HDL ratio), blood pressure, resting pulse, and QRISK calculation. Elevated LDL cholesterol affects roughly one in three UK adults and carries no symptoms. Early detection allows dietary and lifestyle interventions — and medication when warranted — before atherosclerosis progresses.
Metabolic Health
Fasting glucose and HbA1c reveal where you sit on the blood sugar spectrum. The UK has a significant prediabetes burden — many people are in a highly treatable window without knowing it. Liver function tests and kidney function (eGFR, creatinine) round out the metabolic picture.
Thyroid Function
TSH, Free T4, and Free T3. Thyroid dysfunction — underactive or overactive — is common, particularly in women, and frequently undiagnosed. Untreated hypothyroidism affects cardiovascular health, bone density, mood, fertility, and energy over time.
Key Nutritional Markers
Ferritin, vitamin D, B12, and folate. These four markers cover the most common correctable deficiencies in the UK population. Depletion is silent but has measurable consequences for energy, immune function, bone health, and neurological wellbeing.
Hormonal Health
Testosterone in men; oestrogen, progesterone, and FSH/LH in women. Hormone decline begins earlier than most people realise — low testosterone in men from the late 30s, perimenopause in women from the mid-40s (and sometimes earlier). Early identification allows early intervention and meaningful quality of life improvement.
Cancer Markers (Where Indicated)
PSA for men over 45–50, CA-125 where appropriate, and other markers based on risk profile and family history. These aren't diagnostic tests, but elevated results prompt further investigation at a stage when outcomes are typically better.
GP Consultation to Interpret Results
Results without interpretation are just numbers. The GP consultation that follows your blood work puts results in the context of your history, your risk factors, and your goals. This is where the health check becomes genuinely useful: not just knowing what your cholesterol is, but understanding what it means for you specifically and what to do about it.
When Should You Start?
The honest answer: earlier than you think. Most GPs recommend annual health monitoring from age 35–40, with more frequent reviews for those with risk factors. But for anyone with a family history of heart disease, diabetes, or early cancer, starting in the early 30s is reasonable.
The earlier you establish your baselines, the more meaningful your year-on-year trends become. A cholesterol reading in isolation tells you where you are. Ten years of annual readings tell you where you're heading — and gives you the information and time to change direction.
Health Checks for Executives and Professionals
For senior professionals and executives, a comprehensive annual health check has specific value: it provides a structured health audit during periods when self-care often takes a back seat to professional demands. High-achieving adults frequently ignore early symptoms, normalise fatigue, and delay medical appointments. A scheduled annual review removes that friction and creates accountability.
Our Health MOT at Lambert Medical Practice is designed for exactly this purpose: a thorough, GP-led assessment that gives you a clear picture of your health, a report you can act on, and a clinical relationship that tracks your progress year on year.
