Blood lipid abnormalities refer to the imbalance of various lipids in the blood, including total cholesterol, triglycerides, high-density lipoprotein (HDL) cholesterol, and low-density lipoprotein (LDL) cholesterol. HDL cholesterol is considered "good" cholesterol as it helps protect against heart disease, while high levels of LDL cholesterol and triglycerides are considered "bad" as they can lead to the accumulation of lipids in the blood vessels, causing damage. The common types of blood lipid abnormalities include high cholesterol, high triglycerides, high LDL, and low HDL. To manage blood lipid abnormalities, lifestyle changes such as weight loss, dietary adjustments, increased physical activity, and quitting smoking and limiting alcohol consumption are recommended. For those who need medical treatment, statins and other medications can help lower LDL cholesterol and increase HDL cholesterol. Additionally, traditional Chinese medicine and certain foods like oats, celery, and winter melon have been found to have a positive effect on blood lipid levels. It is essential to consult with a healthcare professional for proper diagnosis and treatment.
