The prevalence of diabetes is increasing and tends to be younger. In the clinic, the author found that many patients have misconceptions about the knowledge related to diabetes. Patients do not get out of these misconceptions, which will bring many adverse effects to the treatment of diabetes. One of the misconceptions: good blood sugar control is equal to good diabetes control In the mind of diabetic patients, blood sugar is the only important indicator. Is this understanding correct? In fact, blood glucose indicator is really important in diabetes treatment, but it is not the only testing indicator. Take washing your face as an example, we feel comfortable when we wash our face with tap water, why? Because washing our face with tap water makes our face smooth and comfortable because it is smooth! If we wash our face with sugar water we will feel sticky. If the blood flowing in the blood vessels contains too much sugar, it must affect the flow rate of blood, causing a decrease in the ability of red blood cells to transport nutrients, resulting in ischemia, hypoxia, degeneration, necrosis and complications in tissues and organs. In other words, where there is blood circulation, there will be complications, and complications of diabetes will involve the whole body …… However, blood sugar is not the only important indicator, blood sugar is only an external manifestation of diabetes. Even when blood glucose is well controlled, diabetes complications can still occur because there are other factors (such as oxidative stress) that cause a range of complications in diabetes. Complications in diabetes occur mainly in the blood vessels and nerves, and complications can occur in tissues or organs that have blood vessels and nerves, which means that complications from diabetes are systemic and not just a matter of blood sugar. When patients are treated for diabetes in the hospital, the doctor often mentions blood sugar the most, which may create a misunderstanding for the patient, who then belittles the complications of diabetes. In the treatment of diabetes, the cost of controlling blood glucose is much lower than the cost of detecting and treating complications, suggesting that complications are a key factor in the quality of life and longevity of diabetics. Of course, this is not to say that blood glucose is not important in the treatment of diabetes, ideal control of blood glucose is still the basis and prerequisite for the clinical management of diabetes! Myth No. 2: Pay attention to fasting blood glucose only and ignore postprandial blood glucose Fasting blood glucose, is the blood glucose level when the abdomen is emptied and fasted for more than 8 hours. In our normal life, we should eat lunch after breakfast and less than fasting state; eat lunch and less than fasting state, we should eat dinner. If you eat dinner a little later or have a snack after dinner, then, 24 hours a day, fasting time is very little, more in the next day before breakfast that small period of time. If you eat breakfast at 8 o’clock and dinner at 20 o’clock, the time occupied by fasting blood sugar is only 4 hours, while the vast majority of human blood sugar levels are in the postprandial blood sugar state. Therefore, the postprandial blood glucose state is especially important for diabetic patients. The author would like to remind that the majority of patients should not neglect the monitoring of blood glucose level two hours after meal while testing fasting blood glucose. Even if the fasting blood sugar is well controlled, if the postprandial blood sugar is not well controlled, it will bring harm to the body. Myth No. 3: Insulin injection is “addictive” Some diabetic patients have high blood glucose values, but they refuse to inject insulin for fear of addiction. This is not true. Since its discovery by Canadian surgeon Professor Banting, insulin has saved countless lives in clinical practice. Currently, insulin plays an important role in clinical blood sugar control. So, why do patients refuse insulin injections for fear of addiction? This comes from the previous typing and naming of diabetes. In the past, experts believed that taking any oral hypoglycemic drug could not control high blood sugar, and only insulin could control high blood sugar ideally, so this type of diabetes was called “insulin-dependent diabetes”. As a result, many patients believe that insulin injections are addictive. When a specialist tells you that you need insulin injections, don’t worry because insulin injections are not addictive for people with diabetes! In fact, you need insulin injections when no oral hypoglycemic medication can lower your blood sugar to the ideal state. type 1 diabetes and some type 2 diabetes patients who started treatment improperly need external insulin supplementation when their own insulin secretion cannot meet their needs. Diabetes that has to rely on insulin injections to control high blood sugar is called “insulin-dependent diabetes”. Currently, the concept of diabetes treatment is being updated, and clinically early insulin injections can not only lower blood glucose, but also protect the remaining islet cells of the pancreas. This is more beneficial for patients to have sustainable and ideal blood sugar control. Myth No. 4: Diabetic patients without any symptoms do not need treatment Type 2 diabetic patients have two major characteristics, namely insidiousness and latency. type 2 diabetes often has no symptoms in the early stages and is not easily detected by people for its harmful effects. The absence of any symptoms can paralyze the patient and cause diabetes to lurk in the patient’s body for a long time. When a patient feels uncomfortable in a certain area, it is mostly when there are complications of diabetes that have affected human health. Myth No. 5: The condition is mild and does not require treatment. The initial symptoms of type 2 diabetes are often mild, which is the best period for patients to treat, and the stage that patients are most likely to ignore. Any disease is gradually aggravated, therefore, the author reminds the majority of patients to early detection, early diagnosis and early treatment. If found to have diabetes, patients should preferably be hospitalized in a specialist in a large general hospital to understand what diabetes is, how it occurs, and how harmful it is to the body. At the same time, patients need to undergo a systematic examination to find out if there are any complications, which system or organ has developed complications, and to what extent the complications have progressed. The doctor will develop a scientific treatment plan based on the patient’s condition, such as how he or she should eat, what medications to take, and what items to review regularly. It is better for the patient’s health to create a case file and put his or her condition under the control of himself or herself and the doctor in charge. This is important to improve the patient’s quality of life and prolong the patient’s life expectancy.
