In the treatment of diabetes, the use of insulin has always been a problem for everyone! Some diabetics are worried that insulin will become addictive, so they always refuse to use insulin to control their blood sugar, fearing that once they inject it, they will have to inject it for the rest of their lives and never get rid of insulin injections again! In fact, this is one of the most common misconceptions about diabetes among most of our diabetic patients. The answer is of course “no!” Whether a diabetic patient needs to take insulin injections for life depends on the patient’s own condition and type of diabetes, and insulin is not a drug, but a hormone secreted in the body. Insulin is not addictive, and patients do not become dependent on it in any way. Patients with type 1 diabetes have a severe deficiency in their own insulin secretion and can only rely on insulin replacement therapy by injection, while other treatments can only be used as an adjunctive therapy. For most people with type 2 diabetes, insulin secretion is not reduced, but is relatively insufficient due to the body’s insensitivity to insulin or delayed insulin secretion, and if adequate insulin treatment is applied, it may inhibit their own insulin secretion, so oral hypoglycemic drugs are mostly used in clinical practice. Of course, type 2 diabetes patients encounter some special circumstances, such as severe infection, stroke, myocardial infarction, trauma, surgery and other stressful situations, as well as in acute complications such as diabetic ketoacidosis and hyperosmolar coma, it is necessary to inject insulin for a short period of time to strengthen blood sugar control, in order to help patients safely through the stressful period, and then gradually insulin reduction afterwards, transition back to oral drug therapy to take glucose-lowering drugs for the treatment of type 2 Type 2 diabetes. Of course there is a special category of people, that is, pregnant mothers, gestational diabetes which is a type that only appears after a woman of childbearing age becomes pregnant. For this type, although there are many attempts abroad to choose oral medications such as metformin and glibenclamide and they have shown that they are safe for the mother and the baby; however, in our country, because there is no evidence from clinical trials and we are worried about the effect of oral hypoglycemic drugs on the fetus, we still recommend only insulin therapy. However, after delivery, the glucose tolerance test and islet function are reviewed and diabetes is re-typed, and most people are included in type 2, which can control blood sugar with oral medication. Therefore, it is not addictive to inject insulin in diabetes, and the classification of the cause is the basis for choosing a treatment plan. Instead, early use of insulin allows one’s islet cells to “rest and rest!” Protect the function of the islets and promote their recovery. Do not panic when your doctor says you need to use insulin, use it early, treat it early and recover early.
