Many patients have the situation of high blood sugar. High blood sugar can be mainly divided into two aspects: fasting blood sugar and two-hour postprandial blood sugar, among which high fasting blood sugar is the most serious, because the blood sugar of basically everyone will rise after eating, so the two-hour postprandial blood sugar will be taken as an important basis for measuring blood sugar. So how to control fasting blood sugar? To control fasting blood sugar, we should first understand the normal blood sugar value. Generally, the normal fasting blood sugar value is 3.89~6.1mmol/l. If the fasting blood sugar is more than 6.1mmol/l and less than 7.0mmol/l at the time of testing, this data only indicates that the patient’s blood sugar is abnormal, and it is not completely confirmed as diabetes, if the fasting blood sugar exceeds 7.0mmol/l after testing, there is no need to conduct other tests at this time, and basically If the fasting blood glucose exceeds 7.0mmol/l after the test, it will be confirmed as diabetes directly. At this time, you need to control your blood sugar and find a suitable method to help you lower your blood sugar. For patients with elevated fasting blood sugar who have not undergone any treatment, the first step is to regulate their own insulin cell secretion capacity as a prerequisite, reduce the intake of staple foods in terms of diet, and preferably exercise for about half an hour after meals every day, which can solve the body’s inhibition of insulin and help the body to restore insulin cell function, thus helping patients to restore fasting blood sugar. There are also some patients who have used glucose-lowering drugs before, and this time may cause the fasting blood sugar to rise at night. At this time, it is necessary to take glucose-lowering drugs before going to bed and pay more attention to the change of blood sugar two hours after meals, especially for patients who are taking medication, and cannot only pay attention to the fasting blood sugar value. Blood sugar needs to be measured before each meal, especially before breakfast, as long as the blood sugar value is controlled at 4.4-7.0mmol/L, which is more conducive to controlling blood sugar throughout the day. Blood sugar is important to control, as long as the daily diet and daily activities are adjusted, blood sugar can be controlled within the normal range value. But is there no treatment for diabetes other than control? Nowadays, many people, including clinical prescribers, do not know how to better treat type 2 diabetes, and most of them can only tell you helplessly that it is a lifelong disease and there is no way to cure it completely. Most of them can only tell you that this is a lifelong disease and there is no way to cure it completely. Their understanding basically only stays at the level of “sugar reduction method” and prescribing sugar-lowering drugs, without any innovative treatment methods of their own. In fact, medical research today has found that weight loss metabolic surgery can alleviate and treat a portion of diabetes. Surgery is also very effective in the treatment of type 2 diabetes, not only improving blood sugar and metabolic disorders, but also reducing the occurrence of diabetic complications in the long term. A large amount of clinical data proves that the current complete remission rate (clinical cure rate) of weight loss metabolic surgery for type 2 diabetes reaches more than 80%, and the overall effectiveness reaches more than 95%, and it becomes a reality for diabetic patients to get rid of internal medicine to keep their blood sugar stable. After more than 10 years of development, the number of cases now receiving bariatric surgery for obesity and type 2 diabetes is increasing year by year in China, showing a good development trend.
