Normally, we often encounter sugar lovers communicating with each other, saying that you are taking insulin, so you must have a severe type of diabetes, right? So is this the case? In fact, type 1 diabetic patients have very limited pancreatic beta cells, or even complete loss, so they must use insulin therapy to maintain life, so the application of insulin is a normal method, and can not be said to be serious, as long as the normal control of blood glucose levels, it is possible to live a healthy life. Secondly, type 2 diabetic patients, in general, if the onset of long years, there will be secondary oral hypoglycemic drug failure, that is, the oral drug effect is not good, blood sugar can not be controlled, insulin treatment, but only a change in the treatment method, and does not indicate a serious situation. Third, temporary or prolonged insulin is also needed to control blood sugar in other clinical situations such as severe infection, trauma, before and after surgery, and fever. In the case of gestational diabetes, if the blood sugar exceeds the standard, insulin can be applied for a short period of time, which is beneficial to the fetus, and after the birth of the child, it can be considered to change to oral medication, or diet and exercise therapy. Therefore, insulin is not necessarily a serious case of diabetes.
