Diabetes is a lifelong disease that requires lifelong medication, but it varies depending on the type. There are four types of diabetes. The first is type 1 diabetes, which is due to an absolute lack of insulin and requires insulin for life. The second type is type 2 diabetes. Type 2 diabetes can be controlled by oral medication in the early stage, but in the later stage, due to the slow decline of pancreatic function, insulin treatment is needed, and this process still requires lifelong medication. The third type is gestational diabetes. Gestational diabetes is a condition that develops after pregnancy. After termination of pregnancy, some patients’ blood glucose becomes normal, and these patients do not need lifelong use of glucose-lowering drugs. For patients with gestational diabetes, a glucose tolerance test is performed 6 to 8 weeks after delivery to re-evaluate blood glucose and see if the diabetes is true. The fourth major type is the special type of diabetes, which is divided into many kinds, for example, if the diabetes is caused by drugs, some patients can achieve normal blood sugar if the relevant drugs are removed, and these patients do not need to use it for life. There are also some endocrine diseases that cause diabetes, such as pituitary tumor, which causes increased secretion of cortisol and growth hormone. If the pituitary tumor is removed after surgery, these patients can achieve normal blood glucose, and these patients do not need to use glucose-lowering drugs for life after removing the cause. In some patients, such as those who have pancreatic surgery, or those who have severe pancreatitis and diabetes, the pancreas is destroyed, and these patients often need lifelong use of glucose-lowering drugs or even insulin. Then there are diabetes caused by hereditary diseases, genetic abnormalities and defects, and these definitely require lifelong medication. So the different types are still different.
