Low blood pressure (hypotension)

Get your blood pressure checked if you keep getting symptoms like:

• lightheadedness or dizziness
• feeling sick
• blurred vision
• generally feeling weak
• confusion
• fainting

This might mean your blood pressure is too low.

If you get symptoms when you stand up or suddenly change position, you may have postural hypotension.

How to check your blood pressure

You can check your blood pressure:

• by asking if your pharmacist can do it
• by asking your practice nurse or GP to do it
• at home yourself using a home blood pressure monitor – Blood Pressure UK has information about choosing a blood pressure monitor

Low blood pressure is a measurement of 90/60mmHg or lower.

See a GP if:

• you have low blood pressure and keep getting symptoms such as dizziness

Treatment for low blood pressure depends on the cause

If a cause can be found, your GP will be able to recommend treatment to ease your symptoms.

For example, they may suggest:

• changing medication or altering your dose, if medication is the cause
• wearing support stockings – this can improve circulation and increase blood pressure

Medication to increase blood pressure is rarely needed because simple lifestyle measures or treating the underlying cause is usually effective.

Causes of low blood pressure

Your blood pressure can vary depending on the time of day – it gradually increases throughout the day. What you're doing and how you're feeling can also affect it.

There are many possible causes of low blood pressure. It may be low because you're fit and healthy, or you may have inherited it from your parents.

Some people develop low blood pressure as they get older.

It can also be caused by:

• being pregnant
• some medical conditions, such as diabetes
• some types of medication
