The NHS is advising individuals to see their GP if they think they have low blood pressure, as while many associate symptoms such as dizziness with the condition, there's an additional symptom that people often put down to stress and ageing.

According to the health service, confusion can be a sign of low blood pressure, also known as hypotension. If you believe this might be the cause, it's crucial to seek medical attention promptly.

The NHS cautions: "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."

What causes low blood pressure?

Your blood pressure varies depending on the time of day. It may be low because:

• You're fit and healthy
• You have inherited it from your parents
• You are getting older
• You're pregnant
• You have medical conditions such as diabetes
• You are taking certain medicines

What are the 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
• fainting

If you get symptoms when you stand up or suddenly change position, you may have a type of low blood pressure called postural hypotension. The experts say that you should see a GP if you "keep getting symptoms of low blood pressure such as dizziness and fainting."

How often should I get my blood pressure checked?

If you're 40 to 74 years old, you should have your blood pressure checked at least once every five years as part of the NHS Health Check. But if you are not in this age bracket, you should always ask your GP for a check if you are concerned.

How can I lower my blood pressure?
