What do high levels of LDL cholesterol cause?

ANSWER

When you have high levels of LDL, cholesterol builds up in your arteries, the blood vessels that supply oxygen to your heart. The cholesterol can eventually block them and shut off the flow of blood and oxygen to your heart, causing a heart attack.
