Why it usually has no symptoms, what the numbers mean, and how it is managed.

What it is
Blood pressure is the force of blood pushing against the artery walls. It is written as two numbers: the higher one while the heart beats, the lower one while it rests. Consistently raised readings make the heart, kidneys, eyes and brain work harder over years. High blood pressure very rarely causes symptoms, which is why regular checks matter more than waiting to feel unwell.
What to look for
Usually none at all — this is the point of screening
Very high readings can occasionally cause headaches, nosebleeds or visual changes
Diagnosis is based on repeated readings, not a single measurement
Sensible things to do at home
- Reduce added salt and processed foods; most salt comes from bread, stock and processed meat
- Aim for regular activity, such as a brisk 30-minute walk most days
- Limit alcohol and stop smoking
- Take chronic medicine every day, at the same time, even when you feel fine
- Keep a home reading log if we have asked for one
When to see us
- You have never had your blood pressure checked, or not in the last year
