Low blood pressure doesn’t always cause symptoms, but it does have some tell-tale signs that you should get checked.
The condition – which is also known as hypotension – can cause raining, blurred vision, feeling sick or a general feeling of weakness.
Extreme low blood pressure can be life-threatening.
Seek immediate help if you’re also showing signs of cold, clammy skin, shallow breathing, a lack of concentration.
“Low blood pressure is a reading of 90/60mmHg or less. It doesn’t always cause symptoms, but you may need treatment if it does,” said the NHS.
“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.
“If you get symptoms when you stand up or suddenly change position, you may have postural hypotension.”
Medication for low blood pressure is rarely needed, because it’s usually possible to treat the underlying cause of hypotension by making simple lifestyle changes, the NHS added.
Wearing support stockings could help to regulate circulation, and increase blood pressure.
You could also try eating a diet higher in salt, or exercising more often to promote blood flow.
Straining on the toilet, or heavy lifting could also be prompting hypotension symptoms.
Patients with some other medical conditions are more at risk of developing low blood pressure.
Pregnancy, heart problems, dehydration or severe infection could be causing hypotension.
Not getting enough vitamin B-12 and folate can prevent the body from producing enough red blood cells, which causes low blood pressure.
Those older than 65 are more at risk of the condition.
