Venous serum can detect hyperlipidemia, and serum lipid testing is recommended on an empty stomach. Serum lipid tests commonly used in clinical practice include cholesterol, triacylglycerols, phospholipids and free fatty acids. In addition to being used as a diagnostic indicator for lipid metabolism disorders and related diseases, such as hyperlipidemia, serum lipids can also assist in the diagnosis of primary biliary cirrhosis, nephrotic syndrome, hepatitis cirrhosis and malabsorption syndrome. Hyperlipidemia can cause many diseases, such as atherosclerosis, coronary heart disease, cerebrovascular disease, pancreatitis, etc. If the blood lipids are increased, medication is needed according to the type of increased blood lipids, such as Rosuvastatin, Fenofibrate, Ezetimibe, etc.; and cardio-cerebral vascular CTA and other related tests are needed to determine the degree of development of the disease. Since blood lipids are affected by factors such as diet, alcohol consumption and emotional stress, it is more accurate to measure blood lipids by drawing venous blood in the morning on an empty stomach. People with hyperlipidemia are advised to exercise, stop smoking and drinking, eat a light diet, have a regular rest and relaxation schedule, maintain a good state of mind, and undergo regular blood lipid tests and screening for related diseases. If abnormalities in blood lipids are detected, please consult the hospital in time and under the guidance of a physician to avoid the progression of the disease. The above drugs should be used under the guidance of a doctor.
