This person asked me further , ” Stroke sufferers have higher blood volume, higher blood pressure, a higher heart beat, and thicker arteries to ensure more blood supply to the brain”. I must complement him for raising a very valid query. When a person suffers from stroke it is believed that the brain is damaged because of a problem with blood flow. Strokes can happen if:
●An artery going to the brain gets clogged or simply collapses and a part of the brain goes without blood flow for a significant time.
●Stroke may also happen if an artery breaks open and starts bleeding into or around the brain parts.
Having shared as above, high blood pressure can lead to stroke by damaging and weakening your brain’s blood vessels, causing them to narrow down and block the flow of blood to the brain. In the other condition the blood vessels may rupture or leak and cause another type of stroke.
As aha defines blood pressure reading of less than 120 over 80 is considered normal for adults. A blood pressure reading equal to or higher than 140 over 90 is high. Blood pressure between 120–139/80–89 is considered “prehypertension” and requires lifestyle changes to reduce the risk of stroke.
It is been studied extensively that about 87 percent of strokes are caused by narrowed or clogged blood vessels in the brain that cut off the blood fow to brain cells. This is an ischemic stroke. High blood pressure causes damage to the inner lining of the blood vessels. This adds to any blockage that is already within the artery wall.
About 13 percent of strokes occur when a blood vessel ruptures in or near the brain. This is a hemorrhagic stroke. Chronic High BP or aging blood vessels are the main causes of this type of stroke. High BP puts more pressure on the blood vessels until they can no longer maintain the pressure and the blood vessel ruptures over time.
