Prehypertension itself doesn't often have complications. If you have prehypertension, it's likely to worsen and develop into high blood pressure (hypertension). The term "prehypertension" is often used by doctors to signal that it's time to begin making lifestyle changes or, if you have certain conditions such as diabetes, to consider taking medications to stop your blood pressure from rising to definite high blood pressure.

High blood pressure can damage your organs and increase the risk of several conditions including heart attack, heart failure, stroke, aneurysms and kidney failure.
