In the matter of using insulin to treat diabetes, many people have entered a misunderstanding, thinking that insulin is a treatment method used only by people with serious conditions, and after using it, they can never leave it, just like a drug that creates dependence. So when doctors tell them they need to use insulin, some people will be very resistant to it. In addition, nowadays, the better treatment method of diabetes surgery also requires the severity of the disease, so they are even more worried that after using insulin, they cannot be treated with surgery. But in fact, insulin is the hormone that the body uses to regulate blood sugar, and it is because their bodies cannot secrete sufficient insulin that they suffer from diabetes. This is especially true for people with type 1 diabetes, as they may have completely lost their insulin secretion and can only rely on exogenous insulin to help regulate their blood sugar. And for people with type 2 diabetes, the use of insulin does not mean that their condition is already very serious. The elevation of blood sugar is affected by many factors, such as diet, exercise, mood, and one’s own condition at the time, and the severity of diabetes is generally judged by the effects it has on the body, such as the presence of complications and pancreatic function. Generally speaking, as long as the patient has reached a certain weight and still has a certain level of insulin secretion, even if complications occur, diabetes surgery can be used for treatment. We should treat this treatment method of insulin correctly and proceed according to the doctor’s recommendation, and if we are eligible for diabetes surgery, we should also do it as early as possible. For diabetic patients, controlling blood sugar is the most important thing.
