What is high blood pressure?
High blood pressure (hypertension) usually has no symptoms but significantly raises the risk of heart attack, stroke, and kidney disease. It's often picked up during routine checks. Most adults should have their blood pressure checked at least every 5 years, and more often if over 40 or at increased risk. Lifestyle changes and medication, where needed, can bring it under control.
When NHS resources suggest seeing a GP
- You think you might have high blood pressure or might be at risk of having high blood pressure.
- You're aged 40 or over and have not had your blood pressure checked for more than 5 years.
- You often have headaches or blurred vision.
- You have chest pain that comes and goes.
- You have other symptoms you're worried could be caused by high blood pressure.

Common questions
What counts as high blood pressure?
A reading consistently 140/90 mmHg or higher (or 135/85 at home) is considered high in most adults. Blood pressure is often measured a few times to confirm the diagnosis, as single readings can be misleading (white coat effect).
How can I lower my blood pressure?
Lifestyle changes make a big difference: reduce salt, eat more fruit and vegetables, exercise regularly (150 minutes a week), lose weight if overweight, limit alcohol, and stop smoking. Medication may be needed if lifestyle changes aren't enough.
Do I need to take blood pressure medication for life?
Many people need medication long-term, but some — especially with mild hypertension — can reduce or stop medication after significant lifestyle changes. Never stop on your own; a GP will review and adjust treatment based on readings.
