Many health problems, such as diabetes, high blood pressure, thyroid disorders and high cholesterol, grow silently for years before they cause any symptoms. By the time you feel unwell, the condition may already be affecting your heart, kidneys or nerves. An annual health checkup helps you catch these problems early, when they are easier to treat.
But which tests do you really need? A 25-year-old does not need the same tests as a 55-year-old. In this guide, the doctors at UniClinic Health explain the basic tests everyone should do, the extra tests recommended for each age group, and when your results mean it is time to see an endocrinologist.
A yearly health checkup gives you and your doctor a clear picture of your health and how it is changing over time. It helps to:
- Detect diseases early – such as prediabetes, thyroid problems, fatty liver or kidney disease, often before symptoms appear.
- Track your numbers year on year – small changes in blood sugar, cholesterol or blood pressure are easier to spot when you compare reports.
- Lower long-term risk – early lifestyle changes or treatment can prevent heart attack, stroke and kidney damage.
- Save money – treating a problem early usually costs far less than treating complications later.
Lifestyle diseases are now common in India even in young adults, so regular screening is no longer only for older people.1
Whatever your age, most doctors recommend these core tests as part of a yearly checkup:
As you get older, your risk of certain diseases rises, so extra tests are added. The table below is a simple guide based on commonly followed screening recommendations. Your doctor may advise tests earlier or more often if you have a family history or other risk factors.
UniClinic offers ready-made health checkup packages in Kolkata for each stage of life, including regular packages, diabetic packages and senior citizen packages.
Children also need regular check-ups for growth, weight, vision, hearing, dental health and vaccinations. Blood tests such as CBC, vitamin D or a thyroid test are done when the doctor suspects a problem. A paediatrician can advise what your child needs at each age.
Many of the most common abnormal results in a health checkup, such as high blood sugar, abnormal thyroid levels and low vitamin D, are linked to hormones. These conditions are treated by an endocrinologist.
An endocrinologist, or endocrinology doctor, is a specialist in hormones and the glands that make them, such as the thyroid, pancreas, adrenal and pituitary glands. They diagnose and treat conditions like diabetes, thyroid disorders, PCOS, obesity, osteoporosis and other hormonal imbalances.
Consider booking a visit with an endocrinologist if your checkup shows:
- Blood sugar in the prediabetes or diabetes range – HbA1c of 5.7% or more, or fasting sugar of 100mg/dL or more.
- Abnormal thyroid results – high or low TSH, T3 or T4.
- Very low vitamin D or calcium, or signs of weak bones.
- Hormonal symptoms – irregular periods, PCOS, unexplained weight gain or loss, excessive hair growth or constant tiredness.
- Diabetes that is hard to control despite medicines.

An annual health checkup is one of the simplest ways to protect your health. Start with the basic tests every year, add age-specific tests as you get older, and follow up with a specialist when your results are outside the normal range. Abnormal sugar, thyroid or hormone results are best reviewed by an endocrinologist, who can find the cause and guide the right treatment.
Patients in Kolkata can book a checkup at UniClinic Kolkata – Health Packages or consult our endocrinologists, while patients in Siliguri can visit UniClinic Siliguri – Health Packages.
A basic annual health checkup usually includes a complete blood count (CBC), fasting blood sugar or HbA1c, lipid profile, liver function test, kidney function test, thyroid test (TSH), urine routine, vitamin D and B12, along with blood pressure, weight and BMI. Your doctor may add more tests based on your age, symptoms and family history.
Adults should start a yearly checkup from around 18–20 years of age. Basic tests are enough in your 20s, and more tests are added from your 30s and 40s, when the risk of diabetes, high blood pressure, thyroid problems and heart disease starts to rise.
Yes, for most full body checkups you need to fast for 10–12 hours, because fasting blood sugar and lipid profile results are affected by food. You can drink plain water. Take your regular medicines unless your doctor advises otherwise.
See an endocrinologist if your checkup shows high blood sugar or HbA1c, abnormal thyroid levels, very low vitamin D or calcium, or if you have hormonal symptoms such as irregular periods, PCOS, unexplained weight changes or constant tiredness. An endocrinologist can confirm the diagnosis and start the right treatment early.
