The results of the physical examination are usually viewed in this way, for example, the normal value of fasting blood glucose is 3.9-6.1 mmol/L. If the fasting blood glucose is 7.8 mmol/L, it is obviously abnormal and, according to the relevant guidelines, already meets the diagnostic criteria for diabetes. If fasting blood glucose is ≥7.0mmol/L, diabetes can be diagnosed. At this time, we must pay attention to strict control of diet and increase exercise appropriately. The normal value of cholesterol is less than 5.2mmol/L. If the value of cholesterol reaches 7.8mmol/L, it is hypercholesterolemia. At this time, we should pay attention to eat less high-fat food such as pork kidney, pork liver and pork sausage, increase fresh vegetables appropriately, and pay attention to increase exercise, such as running for 30 minutes every day, which can effectively improve blood lipid situation and lower cholesterol level.
