What is a stroke? It is a new style of haircut. No. Through a complex system of arteries, our brain gets a continuous supply of oxygen. Nutrients with the help of blood. The cells of our brain alone use more than 20% of oxygen in our blood. Hence, if the blood doesn’t reach the brain cells, they can begin to die, thus giving us a stroke. The most common stroke is Ischemic stroke. Ischemic strokes occur when the arteries supplying blood to the brain get blocked. Like the roads get blocked in a traffic jam, right? Indeed. Due to bad lifestyle choices and stress, fats and cholesterol gradually start building up in the arteries. Thus, narrow them. If this build up ruptures, a clot may form blocking the complete artery. As a result, the brain cells begin to die due to lack of oxygen and nutrients. Thus, giving us an Ischemic stroke.
