Cholesterol, essential for hormone and cell production, comes in two types: low-density lipoprotein (LDL), known as 'bad cholesterol,' and high-density lipoprotein (HDL), or 'good cholesterol.' High LDL levels increase the risk of heart disease and stroke, while higher HDL levels lower such risks. It is crucial for individuals, particularly women, to monitor cholesterol levels and maintain heart health through lifestyle modifications and regular check-ups.
