Generally speaking, HDL is beneficial to the organism and a slightly higher level does not matter; high total cholesterol requires treatment, especially for patients with underlying diseases such as coronary heart disease and cerebrovascular disease. 1. HDL fights atherosclerosis, while LDL can cause it. For healthy people, LDL and cholesterol are within the normal range, and even if HDL is high, it does not require intervention or treatment. 2. For patients with underlying diseases, such as coronary artery disease and cerebrovascular, because of the presence of risk factors, high total cholesterol needs to be treated even if it is accompanied by elevated HDL. Dyslipidemia can be hazardous to health, so in addition to reasonable diet and exercise, dyslipidemia also requires medical attention to regulate lipids and standardize treatment.
