Diagnosis
High blood pressure (hypertension) doesn't usually have any symptoms, so the only way to find out if you have it is to get your blood pressure checked. Healthy adults aged over 40 should have their blood pressure checked at least once every five years. Blood pressure tests can also be carried out at home using your own digital blood pressure monitor.
Introduction
High blood pressure, or hypertension, rarely has noticeable symptoms. But if untreated, it increases your risk of serious problems such as heart attacks and strokes. If your blood pressure is too high, it puts extra strain on your blood vessels, heart and other organs, such as the brain, kidneys and eyes.
Patient story: "My diet and lack of exercise contributed greatly to my stroke."
Andy Jones liked to eat a lot of salt with his food. Whatever he ate, whether it was a Chinese takeaway or fish and chips, Andy would always add plenty of seasoning which had raised his blood pressure to dangerous levels. High blood pressure caused his arteries to fur up and put extra strain on his heart.
Prevention
High blood pressure can often be prevented or reduced by eating healthily, maintaining a healthy weight, drinking alcohol in moderation, not smoking and regular exercise can also help you lose weight, which will also help lower your blood pressure,
Treatment
Simple lifestyle changes can often help reduce high blood pressure (hypertension), although some people may need to take medication as well. Your GP can advise you about changes you can make to your lifestyle and discuss whether they think you would benefit from medication.
