As the NHS notes, the only way of knowing whether you have high blood pressure is to have a blood pressure test.
All adults over 40 are advised to have their blood pressure checked at least every five years.
Following a formal diagnosis, you’ll usually be required to overhaul your diet in a bid to lower a high reading.
“Eating a diet that is rich in whole grains, fruits, vegetables and low-fat dairy products and skimps on saturated fat and cholesterol can lower your blood pressure by up to 11 mm Hg if you have high blood pressure,” explains the Mayo Clinic.
