High LDL may be associated with recent dietary or lipid metabolism abnormalities. Generally, lipoproteins in the human body can be categorized into five types according to their density: high-density lipoprotein, intermediate-density lipoprotein, low-density lipoprotein, very low-density lipoprotein, and celiac disease. High LDL may be associated with a greasy diet, and obese people may also have high LDL. The pathologic cause of high LDL is abnormal lipid metabolism, which is often viewed clinically as an indicator of atherosclerotic risk. When LDL is elevated, it indicates an increased risk of developing atherosclerosis. In addition, there is a strong correlation between elevated LDL and the onset of coronary heart disease, stroke, and other diseases. For people with elevated LDL, they need to seek prompt medical attention and apply lipid-lowering drugs under the guidance of clinicians to reduce the risk of atherosclerosis.
