According to the NHS, high blood pressure is considered to be 140/90mmHg or higher (or 150/90mmHg or higher if you’re over the age of 80).
Ideal blood pressure is usually considered to be between 90/60mmHg and 120/80mmHg.
“Blood pressure readings between 120/80mmHg and 140/90mmHg could mean you’re at risk of developing high blood pressure if you do not take steps to keep your blood pressure under control,” warns the NHS.
It adds: “Everyone’s blood pressure will be slightly different. What’s considered low or high for you may be normal for someone else.”
