There are many types of diabetes, the most common being type 1 and type 2, which are better known to everyone. The specific distinctions are as follows: 1. Type 2 diabetes is mostly discovered through physical examination or unintentional blood glucose testing, or elevated blood glucose is found when visiting a doctor due to chronic complications; 3. Start with oral medication, and only gradually need to add insulin as the disease lengthens or when blood sugar is not well controlled. If you have diabetes, you must go to the hospital for regular consultation and let the specialist do the typing so that you can guide the treatment in a reasonable way.
