Cholesterol is measured in milligrams per deciliter (mg/dL). LDL ("bad" cholesterol) builds up in arteries, while HDL ("good" cholesterol) removes LDL. Total cholesterol combines LDL, HDL, and 20% of triglycerides. High cholesterol increases heart disease risk. Lifestyle changes (diet, exercise) and medication can help manage levels. Get tested every 4-6 years, or more frequently if at risk.
