Currently, China has become a major diabetes country in the world, and the prevalence of diabetes in China is 9.7%, which is already higher than the world average of 6.4%. There are about 150 million people at risk of diabetes in China, and the awareness rate of diabetes among residents over 18 years old is only 36.1%. In the treatment of diabetes, there are also many patients who have misconceptions about the treatment of diabetes, resulting in failure to achieve the expected results and even causing adverse effects. Here are 7 common misconceptions in diabetes treatment. Li Fucheng, Department of Endocrinology, The First Affiliated Hospital of Henan College of Traditional Chinese Medicine Misconception 1: Fasting blood sugar is important, and it is usually enough to check only fasting blood sugar. Many clinical patients only pay attention to monitoring fasting blood glucose in the morning and neglect to monitor blood glucose two hours after meal, which is wrong. Human blood glucose is in constant fluctuation throughout the day, and a simple point of blood glucose is not enough to reflect the blood glucose level of a person. Recent studies have confirmed that the significance of postprandial blood glucose is even greater than that of fasting blood glucose. Therefore, in order to have a more comprehensive grasp of the blood glucose status so as to adjust the treatment plan more reasonably, patients should conduct blood glucose monitoring at multiple time periods. Of course, patients do not need to monitor blood glucose at multiple time periods every day, but can determine a reasonable monitoring method according to their condition under the guidance of doctors. Myth 2: The faster the blood glucose drops, the better. Some people think that the faster the blood sugar drops, the better the treatment effect is, which is wrong. If blood sugar drops too fast, the body’s internal environment cannot adapt to it immediately, and patients will have discomfort and even hypoglycemia, so the best treatment is to reduce sugar smoothly. Myth 3: The lower the blood sugar, the better, and it does not matter if hypoglycemia occurs. Excessive lowering of blood sugar will increase the risk of hypoglycemia, which can be life-threatening in serious cases. For diabetic patients, the harm of hyperglycemia mainly causes various serious chronic complications and affects patients’ health, but the harm of hyperglycemia is usually long-term and gradual, and is not life-threatening for the time being. In contrast, the harm of hypoglycemia is rapid and sometimes even fatal. Severe hypoglycemia may cause stroke, induce angina pectoris, heart failure and myocardial infarction, and aggravate the patient’s existing retinopathy. Therefore, blood sugar is not as low as possible, but should reach an ideal range, and try to avoid hypoglycemia. Myth 4: Normal blood sugar control means that diabetes is cured. Diabetes is a chronic, lifelong disease, and so far, it can be controlled but not cured. After continuous conventional treatment, many symptoms disappear completely and blood sugar drops to normal, but this does not mean that diabetes has been cured. Myth 5: If you take glucose-lowering drugs, you don’t need to control your diet. Diet control is one of the basic treatments for diabetes, and must be accompanied by the treatment of diabetic patients for life. If you rely solely on glucose-lowering drugs without diet control, the effect of lowering sugar is certainly not ideal, and an overdose of glucose-lowering drugs can cause hypoglycemia and other adverse reactions. Myth 6: Glucose-lowering drugs can damage liver and kidney function and cannot be taken for a long time. The impact of oral hypoglycemic drugs on liver and kidney function is not significant, as long as they are taken in strict accordance with medical advice will not cause serious harm. On the contrary, if long-term hyperglycemia and do not take drugs, then the damage to liver and kidney function will be greater. Diabetic patients taking oral hypoglycemic therapy during the regular review of liver and kidney function, every six months to check the biochemical indicators. Myth 7: Normal glycosylated hemoglobin (HbA1c) means ideal blood sugar control. Glycosylated hemoglobin reflects the average blood sugar of previous 2D3 months. High blood glucose at one time and normal HbA1c indicates good blood glucose control; high blood glucose and HbA1c both indicate poor blood glucose control for a period of time; normal blood glucose at one time and significantly higher HbA1c indicates that more attention was paid to blood glucose control before this blood draw, but blood glucose control in the last 2D3 months is unsatisfactory. Therefore, simultaneous measurement of blood glucose and HbA1c can help to identify stress hyperglycemia and chronic hyperglycemia.
