Preventive health checks: what is actually worth doing, and when

Preventive screening is one of the highest-value things medicine offers — when it is aimed at the right conditions, in the right people, at the right intervals. Aimed carelessly, it produces anxiety, incidental findings that lead nowhere, and follow-up procedures that carry their own risks.

Here is a broad guide. It is not a substitute for advice tailored to your own history, and your doctor may reasonably recommend something different.

In your twenties and thirties

• Blood pressure, checked at least every couple of years — hypertension is common, silent, and very treatable
• Blood sugar, especially if you are overweight or have a family history of diabetes
• Haemoglobin, particularly for women — anaemia is widespread in India and easily missed
• Cervical screening for women from around age 30
• Vitamin D and B12 if you are tired, low, or have limited sun exposure or a vegetarian diet

In your forties and fifties

• Everything above, but consistently rather than occasionally
• A lipid profile, to assess cardiovascular risk
• HbA1c rather than a one-off fasting sugar, which gives a three-month picture
• Thyroid function, particularly for women
• Kidney and liver function as a baseline
• An ECG, and a discussion about cardiac risk if you have a family history

Sixty and beyond

• The panels above, at intervals your doctor advises
• Bone health assessment, especially for post-menopausal women
• Vision and hearing checks — both decline gradually enough to go unnoticed
• A review of every medicine you take, which is one of the most valuable consultations available at this age
• An honest conversation about mobility, balance, and fall risk

What we would gently discourage

Whole-body scans in people without symptoms, and very large test panels ordered without a reason, sound thorough but tend to create problems rather than solve them. They reliably turn up incidental findings — a small cyst, a benign nodule — that then require monitoring, further imaging, and sometimes a biopsy, without improving anyone’s health. Screening earns its place when finding a condition early genuinely changes what happens next.

“A good check-up is defined by which tests it leaves out as much as by which it includes.”

Getting the most from a check-up

Fast if the tests require it, and come in the morning. Bring your previous reports so trends are visible. Write down your family history of diabetes, heart disease, and cancer before you arrive. And book the consultation that goes with the tests — a report nobody explains to you has done only half its job.

If you are unsure which panel applies to you, call us and describe your age, history, and what is worrying you. We would rather recommend a smaller, better-aimed check-up than sell you a longer one.
