There are many diabetic patients who take several glucose-lowering drugs or multiple subcutaneous insulin injections every day. Fasting blood glucose is measured only once in a while. Fasting blood sugar less than 7.0mmol/L is very satisfactory. However, postprandial blood glucose is rarely measured, or even never measured. On the surface, it looks like they are dealing with diabetes quite seriously and think that their blood sugar is well controlled. In fact, an important feature of type 2 diabetes is ignored, namely: postprandial hyperglycemia. Monitoring postprandial blood glucose is the key to type 2 diabetes treatment. When a person is suspected of having diabetes, a glucose tolerance test and insulin release test, as well as a glycated hemoglobin test, should be done. to find out about glucose metabolism and pancreatic function. In addition to monitoring fasting blood glucose and bedtime blood glucose during glucose-lowering treatment for diabetes, more importantly, the blood glucose at the point of highest postprandial blood glucose should be monitored. It is extremely important for type 2 diabetics to control the blood glucose at the highest postprandial period, which lasts for 14-16 hours in total. If only fasting blood glucose is controlled, but postprandial blood glucose is not well controlled, microvascular and macrovascular lesions caused by hyperglycemia toxicity are still inevitable. This point must be paid enough attention to the majority of type 2 diabetes patients. If you only control fasting blood sugar well and ignore postprandial blood sugar, this is undoubtedly a kind of self-comfort for diabetic patients. The long-term hyperglycemia toxicity of type 2 diabetes inevitably leads to microvascular and macrovascular lesions. Coupled with many factors such as age, duration of diabetes, blood pressure, blood lipids, blood viscosity, body immunity, infection and trauma, eye diseases such as blurred vision and fundus hemorrhage, peripheral neuropathy of the extremities such as numbness and pain in the fingertips of both hands and the tips of both toes, limb movement dysfunction and cardiovascular and cerebrovascular pathologies such as palpitations, anterior heart pain, chest tightness and shortness of breath, and diabetic foot such as ulceration and pain in the distal toes are It is not surprising that these difficult to treat complications. Here, I once again solemnly remind: the majority of diabetic patients must pay great attention to postprandial hyperglycemia. Do not ruin your health in the postprandial hyperglycemia. Friends, others can only persuade you to the ears, only your own awareness, see and see through the serious harm and cruelty of postprandial hyperglycemia toxicity, cause your own wake up, will start their own internal motivation, will hang a horse, to seriously control the postprandial blood sugar, only then, to ensure your health and long life. Therefore, even a smart doctor is not as smart as a diabetic patient himself. A smart diabetic patient will have a high quality of life.
