If you are overweight, chances are that your body is trying really hard to maintain its normal functions. Obesity causes additional diseases like high cholesterol and high blood sugar levels which eventually causes damage to the blood vessels of the brain and heart, leading to stroke at times.
Hormone therapies which include estrogen can also lead to a higher risk of stroke. The increased presence of estrogen can cause the thickening of blood in some cases, which may increase the chance for the occurrence of stroke.
Smoking, be it active or passive, can lead to stroke in certain cases. People who smoke will have a lower level of oxygen in their blood and continuous smoking can also lead to an increase in blood pressure, which speeds up the process of stroke.
