A healthy range for total cholesterol levels is typically considered to be below 200 mg/dL. Levels between 200-239 mg/dL are classified as borderline high, and anything above 240 mg/dL is considered high. Maintaining healthy cholesterol levels is essential for reducing the risk of heart disease and stroke. Factors influencing cholesterol levels include diet, physical activity, and genetics. Regular screenings and lifestyle modifications, such as improving diet and increasing physical activity, can effectively manage cholesterol levels and enhance overall cardiovascular health.
