A stroke happens when blood flow to the brain is blocked or a blood vessel bursts. Brain cells begin to die within minutes, making it a medical emergency. Recognizing early signs can save lives.
The leading cause of stroke. Uncontrolled blood pressure damages blood vessels and increases the risk of blockage or rupture.
High blood sugar can damage blood vessels over time, making them more prone to clotting and stroke.
Excess cholesterol can form plaques in arteries, narrowing them and reducing blood flow to the brain.
Nicotine and chemicals in smoke damage blood vessels, increase clot risk, and raise blood pressure, all of which contribute to stroke.
Conditions like atrial fibrillation (irregular heartbeat) can cause blood clots to form in the heart and travel to the brain.
