Triglycerides are the main component of body fat and they constitute the major storage form of fat in fat cells (adipocytes)

<p>Having higher levels of LDLs in the blood stream increases your risk of developing atherosclerosis as it has a high tendency to stick to artery walls and developing plaque that over time can narrow your arteries, slowing down the flow of blood causing angina. HDLs can harvest cholesterol from plaque and deliver it to the liver to remove it from circulation which reduces your risk of CVD</p> Signup and view all the answers

<p>The longer that cholesterol levels are elevated, meaning cholesterol or plaque will accumulate over time leading to an increased risk of CAD from the narrowing of the arteries. This can ultimately lead to a clot which can cause stroke or heart attack</p> Signup and view all the answers
