For people without hypertension and other cardiovascular risk factors, such as smoking, obesity, etc., the cholesterol level of 5.6 is normal and does not require medication. However, for people with hypertension, smoking, obesity and advanced age, cholesterol needs to be further lowered to below 4.1, and lipid-lowering drugs such as statins and fibrates can be taken for lipid control. In addition, cholesterol levels can also be lowered through dietary control, such as low-salt, low-fat and low-sugar diets, do not overeat, eat more vegetables and fruits on weekdays, and advocate smoking cessation and cessation of alcohol, which is more helpful in lowering cholesterol in the body. In addition, increasing daily physical exercise, such as jogging, swimming, mountain climbing, etc., can burn fat to lower cholesterol. Finally, if daily dietary control or physical exercise fails to lower cholesterol levels, medication should be taken under the guidance of a physician.
