Etiology of stroke and Risk Factors
A stroke is developed when the blood supply to part of your brain is interrupted or blocked, depriving brain tissue of oxygen and nutrients. Within minutes, brain cells begin to die. A stroke may be caused by a blocked artery (ischemic stroke) or the leaking or bursting of a blood vessel. Many factors can increase your stroke risk. Potentially treatable stroke risk factors include: Being overweight or obese, Physical inactivity, Heavy or binge drinking and cigarette smoking or exposure to second hand smoke, High cholesterol, and Diabetes.
