Cholesterol and Heart DiseaseIn the annual physical, your doctor checks your cholesterol levels. But what is it? And what do the numbers say about your health?
Cholesterol is a type of lipid or fat. In our bodies, it travels through our blood stream in particles called lipoproteins. Low-density lipoproteins (LDL) are bad because they can lead to a buildup of plaque in arteries.
A mass of plaque can narrow your arteries and restrict blood flow – much like trying to sip juice through a clogged straw. Eventually, the plaque ruptures and a blood clot forms, cutting off the flow of blood, oxygen and nutrients to the brain. Hello, heart attack and stroke!
High-density lipoproteins (HDL), on the other hand, are good because they pick up the LDL clogging your arteries and take it to the liver, where it’s processed and eventually excreted.
A total blood cholesterol level of 200 and above is cause for concern, according to the American Heart Association.
