Common Causes of Strokes

Most strokes happen when clot blocks blood flow to the brain. Strokes can also happen when a blood vessel bursts in the brain. High blood pressure encourages strokes because it can cause a buildup of arterial plaque, which can cause blood clots.

Birth control pills and hormone therapy increases the risk of having a stroke. Hormone therapy for menopause symptoms has less estrogen than birth control pills but still increases the risk of stroke a little bit.

Sleep apnea is a condition that interrupts the breathing process while a person is asleep. It raises blood pressure and the risk of having a stroke.

Other things that increase the risk of stroke include blood clotting disorders and having migraines with auras. Auras are visual changes that happen before having a migraine.

The risk of having a stroke can be cut in half just by lowering high blood pressure and high cholesterol. If a female has high cholesterol, hypertension, obesity, or diabetes, then she should be very cautions when taking birth control pills so that she can lower the risk of having a stroke.
