What is blood pressure?

On average the heart beats around 70 to 80 times a minute. This pumping action drives blood through the arteries out to various parts of the body – it returns to the heart via the veins. Blood pressure is a measure of the force put on the muscular walls of the arteries.

Why is it important?

Hypertension, or high blood pressure, puts strain on the blood vessels. This can lead to structural changes, causing the vessels to thicken and deteriorate and means the heart has to work harder to push blood through. These changes can eventually cause serious problems, including stroke.

There are a number of reasons for this. High blood pressure can cause clots of cholesterol and other fatty substances to break off from the arterial walls, blocking arteries in the brain. It contributes to the furring of arteries, making them more vulnerable to blockage by blood clots. And the excess stress on blood vessels may cause them to burst and lead to bleeding into the brain, another cause of stroke.

How often should it be checked?

People under the age 65 without hypertension should have their blood pressure checked at least once every five years.
However, blood pressure may be checked much more frequently, for instance in women taking the contraceptive pill or who are pregnant, or in people with other medical conditions or who are taking certain medications.

What factors affect blood pressure?

  • Stop smoking
  • Lose any excess weight.
  • Stick to recommended alcohol limits – no more than two or three units per day for women and three to four units for men ( a unit is a small glass of wine, a single measure of spirit, or half a pint of beer ).
  • Avoid binge drinking.
  • Eat a healthy diet low in saturated fat and high in fibre. Include five servings of fruit and vegetables per day.
  • Reduce your salt intake. Avoid adding salt when cooking or at the table.
