Total cholesterol of 6.8 is on the high side. The normal value of total cholesterol in adults is usually less than 5.2mmol/L. When the patient’s total cholesterol value is 6.8mmol/L, it is on the high side. Elevated total cholesterol will cause an increased likelihood of atherosclerosis, leading to the occurrence of many diseases, commonly coronary heart disease, myocardial infarction, stroke, etc. Therefore, for patients suffering from coronary heart disease, cerebral infarction, and other cardiovascular diseases, it is also necessary to monitor the level of total cholesterol in the normal course of life. People with high cholesterol are recommended to have a low saturated fatty acid and low cholesterol diet, increase exercise and control their weight, as well as quit smoking, limit salt and restrict alcohol consumption. When the total cholesterol value is 6.8mmol/L, you need to go to the hospital in time, under the guidance of the doctor to use drugs or lifestyle intervention treatment.
