First of all, a correct understanding of diabetes should be established. Diabetes is a chronic lifelong disease that requires lifelong treatment once it occurs, and there is no cure for it. There is no scientific basis for the so-called “root-cure” reported by individual propaganda in the society. The root cause of diabetes is hyperglycemia, and long-term hyperglycemia can damage blood vessels throughout the body, causing diabetic eye disease, nephropathy, heart disease and cerebrovascular disease, eventually leading to blindness, uremia, myocardial infarction and stroke. Some patients think that high blood sugar is not a problem, so they do not control blood sugar seriously for a long time, and over time, they have different degrees of chronic vascular complications. In fact, high blood sugar can be controlled, and long-term control of blood sugar to a level close to normal can prevent the occurrence of chronic vascular complications, and can prevent the further aggravation of vascular complications that have already appeared. Secondly, comprehensive therapy should be adopted to strive for blood sugar control. The modern advocated comprehensive therapy includes five measures: diet, exercise, medicine, diabetes education and blood glucose monitoring. Diet control is the foundation of diabetes treatment, and no patient is an exception. Exercise promotes blood glucose utilization, and attention is paid to gradual progress. Diabetes education should be given full attention. Patients can master various means of diabetes prevention and treatment by reading diabetes knowledge manuals, listening to lectures and watching video tapes. Medication is an important measure in the treatment of diabetes, but there are many misconceptions. It is not comprehensive to think that new and expensive drugs are good drugs. It is completely wrong to think that insulin is addictive. Because diabetes is a chronic development of the disease, the control of it will become more and more difficult with the prolongation of the disease, the beginning may only need dietary control or a certain oral hypoglycemic drugs on the line, until later often two or three oral drugs still can not, then it is necessary to use insulin therapy, otherwise blood sugar can not be controlled. So, what is the best level of blood sugar to be lowered to? Generally speaking, fasting blood sugar is 4.4-7.0 mmol/L), 2 hours after meal blood sugar 5-8.0 mmol/L. And the elderly can relax the requirements, 1-2 mmol/L higher than the above value. if blood sugar is higher than these standards, high blood sugar damage to blood vessels is inevitable. Therefore, regardless of the kind or several therapeutic measures used, the goal is to control blood glucose to within the above-mentioned range. Whether the blood sugar is controlled within this range can only be known through regular blood sugar checks, which is also called blood sugar monitoring. If blood glucose is not well controlled, blood glucose should be measured at least once every half month (including fasting and 2 hours postprandial blood glucose), and after it is well controlled, blood glucose can be checked once every 1-2 months. If you have the condition, you can also purchase your own blood glucose meter and test your finger blood glucose more diligently to guide the adjustment of medication.
