The Health Check at 40: What Changes From the Thirties

At 40, several things change. Cardiovascular risk starts becoming clinically meaningful. Cancer screening enters the picture for some categories. Vision and hearing begin subtle decline worth measuring. The 40 check builds on the 30 baseline and adds specific new tests — a few worth having, others still not.

What to add to the 30 panel

• New test: ECG at rest · Why at 40: Baseline; catches early arrhythmia · Frequency after: Every 2 years
• New test: Blood pressure daily home for a week · Why at 40: 24-hour BP averages
• New test: Eye exam (comprehensive) · Why at 40: Baseline pressure, retina · Frequency after: Every 2 years
• New test: Dental x-rays + cleaning · Why at 40: Bone loss detection · Frequency after: Annually or biannually
• New test: Prostate exam / PSA (men) · Why at 40: Discussion, not automatic · Frequency after: Every 2-3 years if risk factors
• New test: Mammography (women) · Why at 40: Consider starting · Frequency after: Every 1-2 years per Indian guidelines
• New test: Uric acid · Why at 40: Metabolic panel expansion · Frequency after: Annually if concerns
• New test: HbA1c (if not already) · Why at 40: More sensitive than fasting alone · Frequency after: Annually

What most 40-year-olds should now do routinely

• Blood pressure at home 3-4 times per week.
• Weight and waist monthly.
• Aerobic exercise 150 min/week.
• Strength training 2x/week — muscle mass decline begins here.
• Sleep 7-8 hours consistently.
• Alcohol moderation (2 drinks max/day for men, 1 for women — and less is better).
• Zero tobacco — quitting adds years.

Cancer screening at 40

• Breast: mammography discussion (Indian guidelines suggest 40-45 start; personal risk shapes decision).
• Cervical: HPV testing or Pap smear (should have started at 30, continues at 40).
• Skin: self-examination monthly; annual visit if any moles changing.
• Colon: not yet routinely (50 is standard); consider if family history.
• Oral: dental screening includes oral cancer check.

The specific Indian addition

• Hepatitis B and C screening once — high India prevalence, treatable.
• HIV screening once — de-stigmatised standard care.
• Consider TB screening if any exposure or symptoms.
• Vitamin D more likely to be low; check and treat.

Cardiovascular risk assessment

The specific conversation at 40: calculate your 10-year cardiovascular risk (ASCVD score, Framingham) with your GP. This uses age, sex, BP, cholesterol, smoking, diabetes to estimate the probability of a heart event in the next decade.

• Low risk (< 5%): reassurance, lifestyle continued.
• Intermediate risk (5-20%): consider coronary calcium score to clarify.
• High risk (> 20%): aggressive lifestyle + statin discussion.

Indian-specific: because we're higher-risk at younger ages, some cardiologists recommend calcium scoring at 45 for those with any risk factor.

What NOT to do at 40

• Full body MRI as screening — poor evidence, high cost.
• PET scan as screening.
• Genetic testing without specific indication.
• Extensive tumour marker panels without symptoms.
• Any imaging without specific clinical question.

Vaccine updates at 40

• Confirm Tdap in past 10 years.
• Annual flu.
• Pneumococcal if any chronic condition (asthma, diabetes, kidney).
• Hepatitis A and B if not previously.
• Shingles vaccine consideration (usually 50+).

The record from 40 forward

• Every value from every annual check, in a trend view.
• Vaccinations list.
• Family history updated with any new information.
• Current medicines and any changes.
• Discussions with GP on any risk conversation.

A 40-year-old with a well-maintained record has a much more useful cardiovascular risk conversation than one with only current values. Trend + context is what actually informs decisions about statins, aspirin, BP management.
