High blood cholestereol is a risk factor for cardiovascular disease like heart attacks and strokes. High cholesterol causes deposits in the walls of blood vessels known as atherosclerotic plaques. Plaques can obstruct the blood flow. If the blood flow to a region of the heart is obstructed completely, a heart attack occurs. Similarly, if the blood flow to a region of the brain is obstructed, a stroke occurs. Stroke is sometimes called a brain attack as well.
Cholesterol is fat that rides around in the blood stream. If it encounters more fat they stick together. The more fat you have floating around, the more they stick together. If they stick together in a tight spot in a blood vessel, they cause a blockage. If the blockage is in a heart vessel, your heart (a big muscle) doesn t get enough blood and kinda quot;suffocatesquot; that s where the pain comes from=heart attack. Same thing in the brain. if the brain doesn t get enough oxygen, some of the tissue doesn t get blood and dies. depending where it is depends on what kind of side effects you have=speech, weakness, etc.. High cholesterol also causes high blood pressure. It causes atheroscerosis which is causing hardening of the blood vessels. If the blood vessels can t stretch, the pressure gets high. Think of a garden hose. If the hose was made of concrete, the pressure coming out the end would be strong, or high. If the hose was made of thin rubber, the pressure on the other end would be really light, because the hose would stretch.......does that make sense???? Hope it helps you visualize it...
