What does it mean if high-density lipoprotein (HDL) levels are low?

Low high-density lipoprotein (HDL) refers to blood levels of high-density lipoprotein cholesterol below the normal range. When a blood test shows low HDL levels, it indicates an increased risk of cardiovascular disease. Low HDL levels may be caused by various factors, including genetic predisposition, unhealthy lifestyle habits (such as a high-fat diet, lack of physical activity, smoking), hepatitis, and others. This reduced state may increase the risk of cardiovascular diseases, such as coronary artery disease and stroke. For individuals with low HDL levels, adopting a healthy lifestyle is generally recommended, including increased physical activity, a healthy diet, smoking cessation, and limited alcohol consumption. Medication may also be necessary to raise HDL levels and reduce the risk of cardiovascular disease. If your HDL level is low, it is recommended to consult a physician.
