Hyperlipidemia is defined as blood lipid levels exceeding normal values, including elevated total cholesterol, elevated triglycerides, elevated LDL, and decreased HDL. Lipids are lipoproteins in the body, which clinically mainly include total cholesterol, triglycerides, LDL and HDL. According to China’s Lipid Guidelines, total cholesterol ≥ 6.2 mmol/L, LDL ≥ 4.1 mmol/L, and triglycerides ≥ 2.3 mmol/L can be defined as hyperlipidemia. Patients with hyperlipidemia need to actively control their diets, strictly focusing on low-fat foods, eating less animal fat and animal offal, and eating more green and fresh vegetables. For patients with high risk of cardiovascular and cerebrovascular diseases, oral lipid-lowering drug therapy, such as atorvastatin, fenofibrate and so on. Specific medication needs to follow the doctor’s prescription. Patients with hyperlipidemia should control their diet and choose medication under the guidance of physicians.
