Blood glucose and lipids can be checked by blood sampling and biochemical tests, and blood glucose can also be checked by fingertip blood. The specific methods of blood glucose and lipid examination are as follows: blood glucose: fasting blood glucose and 2 hours postprandial blood glucose can be measured by measuring fingertip blood glucose or drawing blood, and blood glucose can also be measured by drawing blood to test glycated hemoglobin. It takes more than 8 hours to check fasting blood sugar without eating, and the test result is more accurate. The normal value of fasting blood glucose is 3.9-6.1mmol/L, and 2 hours after meal blood glucose is <7.8mmol/L. If fasting blood glucose is ≥7.0mmol/L and 2 hours after meal blood glucose is ≥11.1mmol/L, then diabetes should be diagnosed. Diabetes is also considered if the fasting blood glucose is ≥7.0mmol/L, together with the patient's recent unexplained weight loss. It is advisable to test fasting blood glucose, 2-hour postprandial blood glucose, and glycated hemoglobin once a year for early detection, early diagnosis, and early treatment of diabetes mellitus. Lipids: Blood tests can be performed to detect abnormalities in serum cholesterol, triglycerides, LDL cholesterol, HDL cholesterol, etc. Triglycerides in blood lipids are greatly influenced by diet. It is recommended to have a light diet 1-2 weeks before the test and not to eat fatty foods, such as fatty meat and fried foods. When abnormalities occur in blood lipids, diet as well as medication regulation and exercise should be given. In addition, attention should be paid to the content of LDL cholesterol and HDL cholesterol. HDL is a high-quality protein that can carry cholesterol from the arterial wall to the liver for metabolism, while LDL cholesterol tends to cause atherosclerosis. If elevated LDL cholesterol alone is present, some intervention needs to be given to avoid atherosclerosis due to dyslipidemia.
