High blood pressure

High blood pressure is very common, especially in older adults. There are usually no symptoms, so you may not realise you have it. Things that increase your chances of having high blood pressure include: your age – you're more likely to get high blood pressure as you get older having close relatives with high blood pressure your ethnicity – you're at higher risk if you have a Black African, Black Caribbean or South Asian ethnic background having an unhealthy diet – especially a diet that's high in salt being overweight smoking drinking too much alcohol feeling stressed over a long period

High blood pressure does not usually cause any symptoms. Many people have it without realising it. Rarely, high blood pressure can cause symptoms such as: headaches blurred vision chest pain But the only way to find out if you have high blood pressure is to get your blood pressure checked.

A blood pressure test involves inflating a band (cuff) around your upper arm and measuring the pressure in your blood vessels. If the test shows you might have high blood pressure, you may be asked to: use a blood pressure monitor at home to check your blood pressure regularly over the next few days come back to your GP surgery a few days or weeks later to have your blood pressure checked again wear a portable monitor that takes regular readings over 24 hours This can confirm if you have high blood pressure. What your blood pressure reading means Blood pressure readings are given as 2 numbers, with the first number higher than the second (for example, 130/80). You're usually considered to have high blood pressure if your reading is: 140/90 or higher when checked by a healthcare professional 135/85 or higher when checked at home
