In Type II diabetes, the characteristic feature is that insulin levels can be normal or even high, but the body's cells fail to respond effectively to the insulin that is present. This condition is known as insulin resistance. As a result, glucose cannot effectively enter the cells, which leads to elevated blood glucose levels. Over time, the pancreas may struggle to produce sufficient insulin to meet the body's needs, potentially leading to further complications.

In contrast, Type I diabetes is marked by insufficient insulin production due to the destruction of pancreatic beta cells, resulting in low insulin levels. Type III diabetes is less commonly defined and often refers to types of diabetes associated with other conditions or secondary causes rather than a primary diabetes type. Mild diabetes is not a medically recognized term and does not refer to a specific type of diabetes with defined characteristics.
