Cholesterol by itself isn't bad but excess of it is. It is an important part of all animal cell membranes. It helps maintain both cell membrane structural integrity and it's fluidity. So you see our body needs cholesterol so what you hear and see about it being bad is not really entirely true. Being part all animal cell membranes, cholesterol plays an important part in our body. The problem comes when you have excess of cholesterol in your body. These excess cholesterol will form plaque in the layer of your blood vessel walls. Then overtime these plaques can break open and causes blood clots. Which can block an artery from flowing blood into parts of your body. When an artery that delivers blood to your brain is blocked it can cause stroke and when it is to your heart it can cause heart attack.
