The idea
Preventive health means seeing a professional before something is wrong. Check-ups can catch problems early, when they are often easier to treat — for example high blood pressure, which usually has no symptoms, or dental problems caught before they become painful.
What is recommended depends on your age, sex, family history and country: blood pressure checks, dental check-ups, eye tests, vaccinations and screening programmes for certain cancers are common examples. A doctor or your local health service can tell you what applies to you.
Many people delay seeing a professional because they don’t want to make a fuss, are busy, or are worried about what they might hear. Reasons worth getting checked include pain that doesn’t go away, a lasting change in how your body works, unexplained tiredness or weight change, a lump or mark that changes, or simply a feeling that something isn’t right.
Why it works
Some of the most important health problems give no warning until they are advanced. Regular checks are how you find them early.
A real example
- The situation
- Busi, 42, hasn’t seen a doctor in six years because she feels fine.
- What happened
- A workplace health check finds her blood pressure is high. She starts making changes with her doctor’s advice and has regular checks. Her blood pressure comes down before it causes problems.
- The takeaway
- Feeling fine didn’t mean everything was fine — the check made the difference.
Use this when you are…
- you haven’t had a check-up in years
- you notice a change in your body that lasts
- you are unsure what checks are recommended for you
Common mistakes
- Waiting for symptoms before seeing a professional.
- Assuming you are too young or too healthy for checks.
- Ignoring a lasting change because you don’t want to make a fuss.
What the evidence says
Strong evidence: Many good-quality studies, usually including randomised trials and reviews that pool them, point the same way. Guidelines tend to recommend it.
Many preventive measures, such as blood-pressure checks and vaccinations, have strong evidence. Which screenings are recommended differs by age, risk and country, so local health guidance is the best source.
Where this comes from: World Health Organization (WHO); US Centers for Disease Control and Prevention (CDC).
