What We Know About Cholesterol?
The heart pumps blood through blood vessels called arteries and the blood carries vital oxygen with nutrients needed by tissues and organs throughout the body.
When cholesterol levels are above normal limits and stay high, some remnants of cholesterol are deposited in the arteries and through the years, they are hardened by a fatty substance called cholesterol plaque that accumulates on the walls of the arteries and reduces or blocks blood flow.
The organs supplied by these arteries are damaged because they can not get oxygen and nutrients needed by limiting blood flow through the arteries, so for example when blood flow to the brain is blocked, it causes a stroke or if the plaque completely blocks a coronary artery, is when we are in presence of a heart attack.
