Low blood pressure is a reading of less than 90/60mmHg. It does not always cause symptoms, but you may need treatment if it does.
Symptoms of low blood pressure
Get your blood pressure checked if you keep getting symptoms like:
- lightheadedness or dizziness
- feeling sick
- blurred vision
- generally feeling weak
This might mean your blood pressure is too low.
If you get symptoms when you stand up or suddenly change position, you may have a type of low blood pressure called postural hypotension.
Non-urgent advice: See a GP if:
- you keep getting symptoms of low blood pressure such as dizziness and fainting
How to check your blood pressure
You can check your blood pressure:
- by asking if a pharmacist can do it
- by asking a practice nurse or GP to do it

Understanding your blood pressure reading
If you have a recent blood pressure reading use the NHS Check your blood pressure tool to understand what your reading means. You'll also get information about what to do next.
Important: Regular blood pressure check
If you're 40 to 74 years old, you should have your blood pressure checked at least once every 5 years as part of the NHS Health Check.
Treatment for low blood pressure
If a cause for low blood pressure can be found, a GP will be able to recommend treatment to ease your symptoms.
For example, they may suggest:
- changing medicines or altering your dose, if this is the cause
- wearing support stockings – this can improve circulation and increase blood pressure
Medicine to increase blood pressure is rarely needed because simple lifestyle measures or treating the underlying cause is usually effective.
