Low levels of HDL cholesterol are associated with what risk?

Low levels of HDL cholesterol, often referred to as "good cholesterol," are significantly associated with an increased risk for heart disease. HDL cholesterol plays a crucial role in transporting cholesterol away from the arteries and back to the liver, where it can be processed and removed from the body. Higher levels of HDL are protective against cardiovascular issues because they help reduce the buildup of plaque in the arteries, a condition known as atherosclerosis, which can lead to heart attacks and strokes.

When HDL levels are low, this protective mechanism is impaired, leading to an increased likelihood of developing heart disease. This association is supported by numerous studies that have shown that individuals with low HDL cholesterol levels are at higher risk for coronary artery disease and other cardiovascular events. Consequently, monitoring HDL cholesterol levels is an important aspect of assessing cardiovascular health and risk factors.
