The ideal total cholesterol level for normal adults is 2.83mmol/L-5.20mmol/L. Therefore, total cholesterol of 5.8mmol/L is on the high side, and requires positive adjustments in lifestyle habits and other adjustments. Patients with high cholesterol may be related to poor daily habits, patients usually have less exercise, sedentary, and eat fatty food. It is recommended that patients actively improve bad habits, reduce weight and increase exercise. It is recommended to replace animal oil with vegetable oil, and eat nuts and beans in moderation, which can effectively reduce the total cholesterol level in the blood. Eat more fresh vegetables and fruits to promote metabolism. If the patient’s total cholesterol continues to rise, he/she needs to go to the hospital for an active examination to rule out other pathological factors, such as abnormal liver function, atherosclerosis, coronary heart disease and so on. If such causes are found, the relevant diseases should be actively treated and medication should also be taken to control the elevation of total cholesterol.
