How does age affect blood pressure?
As you get older your blood pressure is likely to rise. This means that you need to have your blood pressure checked every year so that if it does start to rise you can take steps to lower it, such as changing your lifestyle. It does not matter what age you are, 140/90mmHg is the level for high blood pressure for everyone, whether you are 20 or 80. The old saying that the top number (systolic) of you blood pressure should be 100 plus your age is not true.
