Does high blood pressure increase the chance of stroke?

Medically Reviewed by Checkmark Medically Reviewed By: Dr. Sravanthi Sunkaraneni

Yes. Blood vessels that are damaged by high blood pressure can narrow, rupture or leak. This can increase the chance of stroke. Hypertension or high blood pressure can even be a causative agent for the blood clots in the arteries. This clotting of blood can lead to the brain, blocking blood flow and potentially causing a stroke.

A stroke occurs when part of the brain doesn’t get enough oxygen and nutrients. The lack of oxygen occurs because a clot can narrow or block (ischemic stroke) or burst (haemorrhagic stroke) the blood vessels to the brain. This ultimately leads to death of brain cells.  The brain controls the movement and thoughts of a person. So, a stroke can affect a person’s ability to think, move and function. It can also affect language, memory and vision. In a few cases, it can even lead to paralysis or death.

The American Heart Association states that high blood pressure can damage the arteries throughout the body. This leads to conditions in which these arteries can easily burst or clog. Weak or blocked arteries present in the brain can cause higher risk of stroke.
