Full Body Checkup by Age: Which Tests at 20, 30, 40 and 50 Plus
A full body checkup doesn’t need 60 tests. For most adults, the tests worth doing are a handful: blood pressure, blood sugar, cholesterol, weight and waist, eyes and teeth, cervical and breast checks for women, hepatitis B and C once, and bowel, bone and hearing checks later in life. Below is a schedule by age, framed as a list to take to your doctor so they can say which apply to you.
In brief
- Every adult: BP, weight and waist, dentist every 6 to 12 months, eye check every 2 years
- From 20s: hepatitis B and C test once; a first cholesterol test; cervical screening for women from about 25
- From 35 (earlier with risk): sugar test, fasting glucose or HbA1c
- From 40: yearly BP, a baseline eye pressure check, breast screening talk for women
- From 45 to 50: bowel cancer screening
- From 60 to 65: bone density (women), hearing check, yearly eye check

What a full body checkup actually needs to include
A good checkup looks for common problems that stay silent for years and can be caught early: high blood pressure, diabetes, high cholesterol, some cancers, hepatitis, and slow loss of sight, hearing and bone. Everything on this page is on that list for a reason.
Before any test, your doctor should do the free part: ask about your family history (early heart attacks, diabetes, cancers), smoking, naswar or paan, alcohol, medicines and how you’ve been feeling, then measure BP, weight and waist. That five-minute talk often decides more than a long lab report.
Many South Asians carry extra risk. Diabetes and heart disease tend to start younger and at a lower body weight than in Europeans, which is why the waist line for us is 90 cm for men and 80 cm for women, and why sugar testing may start earlier.
Full body checkup test list by age
This is a general schedule for healthy adults. Your doctor may start earlier or test more often if you already have a condition, take regular medicines or have a strong family history.
| Check | When to start | How often if normal |
|---|---|---|
| Blood pressure | 18 | Every 3 to 5 years till 39; yearly from 40 or with risk |
| Weight and waist | 18 | At every check-up |
| Sugar (fasting or HbA1c) | 35, earlier with risk | Every 3 years; yearly if borderline |
| Cholesterol (lipid profile) | 20s | Every 4 to 6 years; more often with risk |
| Hepatitis B and C | Adulthood | Once, then only with new risk |
| Dentist | Childhood | Every 6 to 12 months |
| Eyes | Childhood | Every 2 years; yearly after 60 or with diabetes |
| Bowel cancer screening | 45 to 50 | Depends on the test chosen |
| Bone density (women) | 65, earlier with risk | As your doctor advises |
| Hearing | Around 60, sooner if family notice | As your doctor advises |
In your 20s and 30s
Get your BP checked at least every few years, and know your number. The house lines: 140/90 or above in a clinic, or about 135/85 or above on a home machine, counts as high, while 180/120 with chest pain, breathlessness, weakness or a severe headache is an emergency. Our guide to checking BP at home the right way shows how to get a reading you can trust.
Have a hepatitis B and C blood test once, since both are common in Pakistan and India and can be silent for decades; the hepatitis B and C testing guide explains which test and the vaccine. A first lipid profile in your 20s gives a baseline. Women start cervical screening from about 25 (21 in some countries).
From 35 to 40
Sugar testing starts at 35 for everyone, and earlier for anyone with a BMI of 23 or more plus another risk: diabetes in a parent or sibling, high BP, PCOS, diabetes in a past pregnancy, or a big waist. The two lines a doctor uses to diagnose diabetes are fasting sugar of 126 mg/dL or HbA1c of 6.5%. The blood sugar level chart explains the numbers in between.
From 40, check BP every year, and get a full eye check with eye pressure as a baseline, because glaucoma and diabetic eye changes give no warning early on.
From 45 and 50 plus
Bowel cancer screening usually starts between 45 and 50: a yearly stool test for hidden blood, or a colonoscopy at longer intervals. Women should ask about mammograms; guidance varies by country, typically every 1 to 3 years starting somewhere between 40 and 50. Anyone with diabetes should also have a yearly kidney check (a creatinine blood test and a urine albumin test) and a yearly retina check, as set out in the diabetic eye check guide.
60 and over: full body checkup for senior citizens
Add a hearing check, a yearly eye check for cataract and glaucoma, and a bone density scan for women from 65 (earlier after an early menopause, a fracture from a small fall, or long-term steroid use). Ask the doctor to review every medicine once a year, and to ask about falls, memory and mood.
Full body checkup package for women: what to add
- Cervical screening: a Pap smear every 3 years from about 25, or from 30 an HPV test every 5 years, until about 65. Ask which your clinic offers.
- Breasts: know how your breasts normally look and feel, and see a doctor promptly about a new lump, dimpling, nipple change or discharge. Mammograms as above; earlier with a strong family history.
- Anaemia: a blood count (CBC) is worth doing if periods are heavy, you’re tired and pale, or you’re planning a pregnancy.
- Thyroid: a TSH test makes sense with symptoms (weight change, hair fall, feeling cold, irregular periods) or before pregnancy, rather than as a yearly routine for everyone.
- Bone: bone density from 65, or earlier after menopause with risk factors.
Myth: a 60-test package is better value than a 10-test one
Big packages look like good value. More tests, same price. The catch is that every extra test on a healthy person raises the chance of a result that’s slightly outside the range, and that “borderline” figure then leads to repeat tests, specialist visits, worry and sometimes scans you didn’t need. Tumour markers, vitamin panels and “toxin” screens in healthy people are the usual culprits.
Tests are useful when there’s a reason for them: your age, your sex, your family history, or a symptom. A short, targeted list that your doctor actually reads beats a 40-page report nobody explains.
What to ask a lab before you book
Is the lab accredited (for example ISO 15189, through PNAC in Pakistan or NABL in India)? Do I need to fast, and for how long? Will a doctor go over the results with me? Can I choose single tests instead of a package? Bring last year’s report so results can be compared.
Missed years of checkups? The busy-person version
Don’t try to catch up on everything at once. Start with the three that find the most silent trouble: a BP reading, an HbA1c or fasting sugar, and a lipid profile, plus hepatitis B and C if you’ve never had them. One morning, one blood draw, one visit to go over the results. Then put the next due date for each test in your phone calendar with a yearly reminder, so a missed year becomes a note to book, not a guilt trip.
You notice chest pain, breathlessness, a BP of 180/120 with symptoms (that’s an emergency), unexplained weight loss, blood in urine, stool or cough, a new lump, a mole that changes, constant thirst and passing urine a lot, or yellow eyes. A checkup is for people who feel well. And if you already take medicines for BP, sugar or cholesterol, never change or stop them based on a lab report alone; take it to the doctor who prescribes them.

Questions people ask about a full body checkup
What does a full body checkup include?
A sensible one covers BP, weight and waist, sugar (fasting or HbA1c), a lipid profile, and, depending on your age and sex, hepatitis B and C once, cervical and breast screening, bowel screening, eyes, teeth, bone density and hearing. Extra tests should have a reason, such as a symptom or family history.
How often should I get a health check up?
There’s no single rule, and a yearly “everything” package isn’t needed. Follow the per-test timings in the table above: under 40 with normal results, BP every 3 to 5 years and the other tests at their own intervals; from 40, a yearly BP check and doctor’s visit suits most people. With diabetes, high BP, heart or kidney disease, your doctor sets the schedule, often much more often.
Should I fast before a full body checkup?
For fasting sugar, yes, usually 8 to 12 hours with only water. Many labs now accept non-fasting cholesterol tests. Ask the lab when you book, and take your usual medicines unless your doctor says otherwise.
What is the right age to start a full body checkup?
From 18, a BP check and a weight and waist measure are worth doing, plus hepatitis B and C once. Sugar testing starts at 35, or earlier with risk. Most other screening tests begin in your 40s and 50s.
What tests are included in a full body checkup for senior citizens?
For people over 60, the useful core is BP, sugar, cholesterol, kidney function, a blood count, eye and hearing checks, bone density for women, bowel screening up to about 75, and a yearly review of every medicine they take. Falls, memory and mood deserve a question too.
Is HbA1c better than a fasting sugar test?
Neither is simply better. HbA1c shows your average sugar over about three months and needs no fasting; fasting glucose is a snapshot of one morning. Doctors use either, and 6.5% or 126 mg/dL is the line for diagnosing diabetes.
Do I need a thyroid test every year?
Not usually, if you feel well and have no thyroid history. A TSH test is worth doing with symptoms, before or during pregnancy, or with a strong family history, and regularly if you already take thyroid medicine.
Are vitamin D and B12 tests part of a routine checkup?
Not for everyone. They make sense with symptoms such as tiredness, bone or muscle aches, or tingling, and for people with risks: little sun exposure, a vegetarian diet (for B12), or long-term use of certain diabetes or acid medicines.
Is a full body checkup at home reliable?
It can be, if an accredited lab collects the samples and the samples reach the lab quickly. The weak point is usually not the test but the follow-up, so make sure a doctor reviews the results with you.
My report has one value slightly out of range. Should I worry?
Usually not by itself. A small change in one result is common in healthy people. Show the full report to a doctor, who will decide whether to repeat it, compare it with older results, or leave it.
What is the waist size limit for South Asians?
The guide is 90 cm for men and 80 cm for women. Above that, the risk of diabetes and heart disease rises, even when BMI looks normal.
How often should I see a dentist?
Every 6 to 12 months for most adults, and sooner for bleeding gums, a loose tooth or pain. Smokers and people with diabetes often need more frequent checks.
Can I skip the checkup if I feel fine?
That’s exactly when checkups are useful. High BP, diabetes, high cholesterol and hepatitis often cause no symptoms for years, and a simple test is the only way to find them early.
