Total cholesterol of 7.1 mmol/L is considered hyperlipidemia, which is a more serious condition requiring lipid-lowering drugs, strict dietary control and increased exercise for relief. Total cholesterol usually refers to the cholesterol contained in various lipoproteins in the serum, and the normal range of total cholesterol in adults is 2.83 to 5.20 mmol per liter. Total cholesterol of 7.1 mmol per liter, which is already above the upper limit of normal, is a more serious condition that may lead to the development and progression of atherosclerotic disease. For patients with elevated cholesterol, they should adopt good dietary habits, such as reducing the intake of high-fat, high-calorie and high-sugar foods, as well as increasing exercise to promote the body’s metabolism. In addition, lipid-lowering drugs such as pravastatin and simvastatin should be taken under doctor’s supervision to help control the total cholesterol level. Patients with total cholesterol of 7.1 mmol per liter should consult a doctor in time to choose the appropriate lipid-lowering drug under the advice of a medical professional and take it according to the doctor’s instructions in order to avoid adverse consequences.
