Cholesterol is a waxy substance your body needs to build cells. But when thereโs too much of certain types in the blood, it can raise the risk of plaque build-up in the arteries.
LDL is often called โbadโ cholesterol because high levels of it can contribute to fatty build-up in the arteries. This can narrow the blood vessels and increase the risk of heart attack and stroke.
HDL is often called โgoodโ cholesterol because it helps carry cholesterol away from the arteries and back to the liver, where it can be removed from the body.
Triglycerides matter too. High triglycerides, especially together with high LDL or low HDL, can further increase heart health risks.
Your cholesterol numbers are best understood together โ not one number at a time. Speak to your doctor about what your results mean for you.
