Many people only visit a doctor when something hurts.
But some common health conditions develop quietly and cause no symptoms at first.
This page explains why simple, regular check-ups matter and what you can do every day to look after your health.
The aim is awareness, not worry.
Why Check-Ups Matter
The NHS notes that many warning signs for heart and blood vessel problems, such as high blood pressure and high cholesterol, do not cause symptoms.
A check-up can show whether you are at higher risk, so you can act early with lifestyle changes or, if your doctor advises, medicine.
Blood Pressure: The Quiet Condition
- High blood pressure (hypertension) means pressure in your blood vessels of 140/90 mmHg or higher, according to the World Health Organization (WHO).
- Most people with high blood pressure feel nothing. The only way to know is to have it measured.
- WHO estimates that around 44% of adults with high blood pressure don’t know they have it.
- If it isn’t treated, it can lead to heart disease, stroke and kidney problems.
Measuring blood pressure is quick and painless, and a health professional can interpret the result for you.
Blood Sugar and Diabetes
- Diabetes affects how your body handles sugar (glucose). Over time, high blood sugar can damage nerves and blood vessels.
- Possible symptoms include feeling very thirsty, passing urine more often, blurred vision, feeling tired and unintentional weight loss.
- In type 2 diabetes the symptoms can be mild and may take years to notice. WHO says regular check-ups and blood tests are the best way to find it early.
What a Basic Check-Up May Include
Check-ups differ between countries and doctors.
As an example, the NHS Health Check in England usually covers height, weight and waist measurements, a blood pressure test, a cholesterol test and sometimes a blood sugar test, plus questions about family history, smoking, alcohol and activity.
Ask your own doctor which tests suit your age, family history and lifestyle, and how often to have them.
Everyday Steps That Support Your Health
WHO lists these lifestyle steps for lowering blood pressure and the risk of type 2 diabetes:
- Eat more vegetables and fruit
- Be physically active, with at least 150 minutes of moderate activity a week, and strength exercises on two or more days
- Sit less
- Keep to a healthy body weight
- Keep salt below 5 grams a day (about 2 grams of sodium)
- Avoid tobacco and limit alcohol
Small changes count. You don’t need to do everything at once.
When to Get Help Quickly
Very high blood pressure (usually 180/120 or above) can cause severe headache, chest pain, difficulty breathing, dizziness, blurred vision or confusion. WHO advises seeking care immediately if you have these symptoms with high blood pressure. Don’t wait for a routine appointment.

Final Thoughts
Knowing your numbers is a simple way to look after yourself. If you haven’t had a check-up in a while, consider booking one, and take any questions with you.
