Explain how hypertension, heart disease, and stroke are related.

Hypertension is another term for high blood pressure. This occurs when there is too much pressure put on the blood vessels. The heart gets affected because it is pumping against the pressure, which causes strain on the heart. This can cause thickening of the heart walls, which can lead to other heart problems.

Stroke occurs when there blood supply to the brain is reduced or obstructed. This deprives the brain of oxygen and other nutrients. The occurrence of stroke increases with blood pressure because there is persistent pressure on the vessels which can ultimately lead to stroke.
