Most men reach 40 without having had a single meaningful health check. Statistically, men are less likely than women to visit a GP, less likely to attend health screenings, and more likely to present to healthcare services only when a problem has already developed. The conditions that kill men in midlife — heart disease, type 2 diabetes, hypertension — build silently over years before producing any symptoms.
Forty is the age at which several of these risks begin to accelerate. It is the ideal time to establish a baseline, understand your numbers, and make informed decisions about your health before problems develop rather than after they have.
Why Does 40 Matter for Men’s Health?
The risk of cardiovascular disease, type 2 diabetes, and testosterone deficiency all increase meaningfully from the age of 40. For most men, this is not something they feel — it is something a blood test reveals.
NHS guidance on men’s health aged 40 to 60 highlights that this is a critical decade for establishing healthy habits and identifying risk factors before they cause irreversible damage. Cardiovascular disease remains the leading cause of death in men in the UK, and the majority of men who have a heart attack had elevated risk factors that were measurable — and modifiable — years before the event.
The challenge is that high blood pressure, high cholesterol, early type 2 diabetes, and even significantly elevated cardiovascular risk rarely cause noticeable symptoms. A man can feel entirely well while carrying a ten-year heart attack risk that warrants treatment. Screening at 40 establishes the baseline that makes future changes detectable and early intervention possible.
What Does the NHS Offer Men at 40?
The NHS Health Check is the starting point — and it is worth understanding both what it covers and where it stops.
The NHS confirms that the Health Check is offered free every five years to adults aged 40 to 74 in England who have not already been diagnosed with a cardiovascular condition, diabetes, or chronic kidney disease. It includes blood pressure, cholesterol, blood glucose or HbA1c, BMI, and a QRISK cardiovascular risk score calculated from these combined results.
This is a genuinely useful screen. It identifies men at elevated cardiovascular risk who may benefit from lifestyle changes or medication, and it is free, accessible, and well evidenced.
What it does not cover is equally important to understand. The NHS Health Check does not include testosterone, full thyroid function, liver function beyond the basic metabolic picture, ECG, PSA, or inflammatory markers. For a man at 40 who wants a comprehensive picture of his health rather than a cardiovascular risk calculation, a private health check covers the ground the NHS check does not.
What Should Men Screen for at 40?
The following markers form a comprehensive screening checklist for men at 40. Some are available through the NHS; others require a private assessment.
Cardiovascular Risk
Heart disease is the single biggest killer of men in the UK, and the foundations of cardiovascular disease are laid in the years before any symptoms appear.
A thorough cardiovascular screen at 40 should include blood pressure, a full fasting lipid panel (total cholesterol, HDL, LDL, and triglycerides), HbA1c, and a resting ECG. NICE cardiovascular risk guidelines recommend that lipid modification and cardiovascular risk assessment should be offered to all adults — and that a full formal risk assessment is the appropriate basis for treatment decisions, rather than any single marker in isolation.
An ECG adds something blood tests cannot provide — a direct recording of the heart’s electrical activity, identifying arrhythmias such as atrial fibrillation that are entirely silent but significantly increase stroke risk. Our ECG heart health check-up provides a same-day result reviewed by a GP, and it is a component of every thorough men’s health check at 40.
Metabolic Health
Type 2 diabetes and metabolic syndrome — a cluster of conditions including abdominal obesity, high blood pressure, high blood sugar, and abnormal cholesterol levels — are increasingly common in men from their forties onwards, often without symptoms.
HbA1c measures the average blood glucose level over the previous three months and is the most reliable screening test for type 2 diabetes and pre-diabetes. It is particularly important for men who are overweight, physically inactive, have a family history of type 2 diabetes, or are of South Asian, Black African, or Black Caribbean heritage, all of whom carry elevated baseline risk.
Waist circumference is a more meaningful measure of metabolic risk than BMI alone. Visceral fat — the fat stored around the internal organs rather than under the skin — drives insulin resistance, inflammation, and cardiovascular risk. A waist circumference above 94cm in men is associated with increased health risk; above 102cm, the risk is substantially elevated.
Liver function tests are worth including at this stage. Non-alcoholic fatty liver disease (NAFLD) is increasingly prevalent in men with metabolic syndrome and is frequently asymptomatic until significant liver damage has occurred. A routine liver function panel can detect early abnormalities that allow intervention well before organ damage becomes irreversible.
Testosterone and Hormonal Health
Testosterone levels in men begin to decline gradually from around the age of 30 and the rate of decline increases from 40 onwards. For many men, this is entirely normal and does not produce significant symptoms. For others, testosterone deficiency causes a meaningful deterioration in quality of life.
Symptoms of low testosterone include persistent fatigue, reduced libido, low mood or depression, reduced muscle mass and strength, increased body fat, difficulty concentrating, and poor sleep. These symptoms are frequently attributed to stress, ageing, or lifestyle — and frequently dismissed without testing.
A testosterone blood test alongside SHBG and LH is the appropriate first step. Our private blood tests include testosterone and hormonal panels that are not routinely available through NHS primary care without a specific clinical referral. If testosterone deficiency is confirmed, a treatment discussion with your GP can follow — the blood test is simply the starting point.
Kidney and Liver Function
Kidney disease and liver disease both develop silently — many people have significantly impaired organ function before they experience any symptoms at all. By the time symptoms appear, the opportunity for early intervention has often passed.
A standard renal function panel (creatinine, urea, eGFR) gives a reliable picture of kidney health. Combined with liver function tests (ALT, ALP, GGT, bilirubin, albumin), these markers form a straightforward and informative screen for two organ systems that bear the brunt of decades of diet, alcohol consumption, and metabolic strain.
Thyroid Function
Thyroid disorders are less common in men than in women, but they are not rare — and they are frequently missed because their symptoms overlap with so many other conditions. Hypothyroidism causes fatigue, weight gain, low mood, poor concentration, and feeling cold. In a man at 40 who attributes these symptoms to work stress and ageing, an underactive thyroid can go undetected for years.
A thyroid stimulating hormone (TSH) test is a simple and inexpensive screen. If TSH is abnormal, a full thyroid panel including free T4 can clarify the picture. It takes minutes to add to a blood panel and can identify a straightforward, treatable cause of symptoms that significantly affect daily life.
PSA (Prostate-Specific Antigen)
PSA testing is not part of any routine NHS screening programme, and the decision to have it at 40 should be an informed one made in discussion with your GP rather than a default inclusion.
PSA measures the level of prostate-specific antigen in the blood. Elevated PSA can indicate prostate cancer, but it can also be raised by benign prostatic enlargement, prostatitis, or recent physical activity. A normal PSA does not definitively exclude prostate cancer, and a raised PSA does not confirm it.
At 40, PSA testing is most relevant for men with a first-degree relative diagnosed with prostate cancer, men of Black African or Black Caribbean heritage (who have approximately double the risk of prostate cancer compared to white men), or those with urinary symptoms such as difficulty starting urination, poor flow, or needing to urinate frequently at night. For these men, establishing a PSA baseline at 40 provides a reference point for monitoring any future changes.
What Lifestyle Factors Should Men Discuss at 40?
A health check is not just about blood results. A GP consultation at 40 is an opportunity to review the lifestyle factors that will determine your health trajectory over the next two decades.
NHS guidance on men’s health identifies blood pressure monitoring, alcohol intake, smoking, and weight management as priority areas for men in this age group. Men are more likely than women to drink above NHS recommended limits of no more than 14 units per week, and alcohol has a direct impact on blood pressure, liver function, cardiovascular risk, and testosterone levels.
Smoking remains the single most modifiable cardiovascular risk factor. If you smoke, no health check result is more important than this conversation with your GP.
Sleep quality deserves mention. Poor or disrupted sleep is associated with elevated cortisol, suppressed testosterone, increased cardiovascular risk, and impaired glucose metabolism. Men who consistently sleep fewer than six hours or report poor quality sleep should raise this at their health check appointment — it is a clinical issue, not a lifestyle preference.
Mental health is perhaps the least discussed but most important component of a men’s health check at 40. Men are significantly less likely to seek help for mental health difficulties than women, and suicide remains the leading cause of death in men under 50 in the UK. A GP appointment at 40 is a natural opportunity to raise concerns about mood, anxiety, stress, or alcohol use in a clinical context.
What Happens After the Health Check?
A health check is only useful if the results lead somewhere. At The Private GP, results are reviewed and discussed by a GP at the appointment — not sent in a letter with no context.
If all results are normal, you leave with a clear baseline and the reassurance of knowing your numbers. Your GP will advise on appropriate frequency for future checks based on your individual risk profile.
If something warrants attention, your GP will explain what has been found and what the appropriate next step is. This might mean a repeat test to confirm a finding, a lifestyle intervention with follow-up monitoring, a referral to a specialist. Nothing is left unexplained. You leave with a clear understanding of what your results mean and what, if anything, needs to happen next.
At The Private GP in Birmingham, our full health check-up covers the markers that matter most for men at 40 — physical examination, blood tests, ECG, and a GP consultation with same-day results. No referral needed, no waiting list. Book your appointment today.
Frequently Asked Questions
Is the NHS Health Check enough for men at 40?
It is a valuable starting point and covers cardiovascular risk well. It does not include testosterone, full thyroid function, ECG, liver function, or PSA — all of which are relevant for men at 40. A private health check complements rather than replaces it.
Should men have a PSA test at 40?
Not automatically. PSA at 40 is most relevant for men with a family history of prostate cancer, men of Black African or Black Caribbean heritage, or those with urinary symptoms. Discuss with your GP whether it is appropriate for your individual circumstances before testing.
How often should men have a health check after 40?
Annually for those with risk factors such as high blood pressure, high cholesterol, diabetes, obesity, or a family history of heart disease. Every two to three years for those without significant risk factors, alongside the free NHS Health Check every five years.
Can low testosterone be detected at a health check?
Yes. A testosterone blood test alongside SHBG and LH can confirm whether levels are within the normal range. If deficiency is identified, your GP will discuss whether treatment is appropriate based on your symptoms and results.
What are the signs that a man at 40 needs a health check urgently?
Chest pain, palpitations, unexplained breathlessness, severe persistent fatigue, significant unintentional weight loss, difficulty urinating, or any symptom that is new, worsening, or causing concern warrants prompt GP assessment — do not wait for a scheduled health check.
