In people’s impression, the mention of high blood lipid will come to mind the word obesity, it seems that high blood lipid is only fat people’s patent, thin people can not suffer from high blood lipid, this view is actually wrong. This view is actually wrong. There is no inevitable connection between high blood lipid and fat and thin. May be the body type of obese people see, but thin people suffering from this disease is not uncommon. Thin people with high blood fat tend to be more serious. Clinically, hyperlipidemia in thin people is often characterized by high LDL cholesterol and low HDL cholesterol levels. LDL cholesterol is known as the “bad” cholesterol, and its increase can directly lead to endothelial damage, causing endothelial cells to degenerate, necrosis, and shedding. After endothelial damage, the increased LDL cholesterol and other lipids and platelets will be deposited in the endothelial damage, and gradually form atherosclerotic plaques to block the blood vessels, triggering coronary heart disease. HDL cholesterol is called “good” cholesterol, which can fight against atherosclerosis and reduce the occurrence of coronary heart disease. Thin people with hyperlipidemia are mostly high in “bad” cholesterol and low in “good” cholesterol, so they are more at risk of developing cardiovascular diseases. In addition, many patients with hyperlipidemia will not have clinical symptoms for a long time after the disease, and thin people often mistakenly believe that they must be with high cholesterol “no chance”, in life and diet are generally not too restrained, so when the symptoms appear, often more serious than others. Therefore, experts remind that thin people must also pay attention to their own lipid profile to prevent the occurrence of cardiovascular disease.
