The heart distributes blood that is circulated to various body organs. The heart places a precise amount of strain on the blood artery walls due to the heart's pumping action. Blood pressure is used to describe this burden. There are two different types of blood pressure: systolic and diastolic. When the heart beats, systolic pressure occurs; however, diastolic pressure occurs when the heart pauses between beats. It is thought that a small variance of about 10% is normal. You also don't need to worry if your blood pressure changes occasionally by about 25 to 30 percent. It has no negative effects on how the body's metabolism functions at all.

But only when it becomes a serious problem should you be concerned.
