Cholesterol is a fatty substance essential for body functions, but high levels can lead to heart disease, stroke, and blocked arteries. It is classified into LDL (bad cholesterol), which contributes to plaque buildup, and HDL (good cholesterol), which helps remove excess fat from the bloodstream. High cholesterol often has no symptoms but increases the risk of serious heart conditions. Management includes a healthy diet, regular exercise, medication, and lifestyle modifications.
