Type 2 diabetes was originally called adult-onset diabetes. It usually develops after the age of 35 to 40, accounting for more than 90% of diabetes patients. The ability to produce insulin in patients with type 2 diabetes is not completely lost. Some patients even produce too much insulin, but the effect of insulin is poor. Therefore, the insulin in the patient's body is relatively deficient. Certain oral medications can be used to stimulate the secretion of insulin in the body. However, some patients still need to use insulin treatment in the later stages.
