High cholesterol typically results from a combination of genetic factors, diet high in saturated and trans fats, lack of physical activity, obesity, smoking, and certain medical conditions like diabetes or hypothyroidism. While high-density lipoprotein (HDL, or "good" cholesterol) helps remove excess cholesterol from the bloodstream, an imbalance favoring LDL promotes atherosclerosis, narrowing arteries over time. Management often involves lifestyle changes such as adopting a heart-healthy diet rich in fruits, vegetables, and whole grains; engaging in regular aerobic exercise; maintaining a healthy weight; and quitting smoking. In many cases, medications like statins are prescribed to lower LDL levels and reduce cardiovascular risk, with regular lipid panel blood tests guiding ongoing care. Board-certified providers like NP Ebony can assess your personal risk factors and develop a tailored prevention or treatment plan.
