First, we can take a blood test to check our cholesterol, triglycerides, low-density lipoprotein, and high-density lipoprotein levels. Second, we can also have a carotid ultrasound to look at the condition of the blood vessels, to see if there is high blood lipid levels, if it has affected the blood vessels, if there is arteriosclerosis, and if plaques have formed. If the diagnosis confirms these conditions, it is advised to control the diet and eat lightly. If diet control is insufficient, then it may be necessary to go to the hospital and choose lipid-lowering medication under the advice of a doctor.
