HOW HIGH BLOOD PRESSURE CAN LEAD TO STROKE
High blood pressure damages arteries throughout the body, creating conditions in which they can burst or clog more easily. Weakened or blocked arteries in the brain put you at a much higher risk for stroke, which is why managing high blood pressure is critical to reducing your stroke risk.
What happens when you have a stroke:-
A stroke occurs when a blood vessel to the brain is narrowed or blocked by a clot (ischemic stroke) or bursts (hemorrhagic stroke). When that happens, part of the brain is no longer getting the blood and oxygen it needs; so it starts to die. Your brain controls your movement and thoughts, so a stroke threatens your ability to think, move and function. Strokes also can affect language, memory and vision. Severe strokes may even cause paralysis or death.
A TIA (transient ischemic attack) is caused by a temporary clot. Often called a “mini stroke,” these warning strokes should be taken seriously.
Don’t let high blood pressure lead to stroke:
- Spot the warning signs of a stroke — F.A.S.T.
- Download a fact sheet about how high blood pressure leads to stroke (PDF).
- Know your blood pressure numbers.
- Make changes that matter to help prevent stroke.
- Learn the important connection between BP, atrial fibrillation and stroke.
Why High Blood Pressure is a “Silent Killer”
A few facts to be aware of:
- Many people with high blood pressure don’t even know they have it. Often the signs and symptoms are misunderstood.
- High blood pressure develops slowly over time and can be related to many causes.
- High blood pressure cannot be cured. But it can be managed effectively through lifestyle changes and, when needed, medication.
