What characterizes Type 2 diabetes?

Type 2 diabetes is primarily characterized by insulin resistance, which means that the body's cells do not respond effectively to insulin. This resistance often leads to elevated blood glucose levels, as the hormone responsible for allowing glucose to enter cells and be used for energy is not functioning optimally. Over time, the pancreas may become unable to produce sufficient insulin to overcome this resistance, contributing to the progression of the disease.

In contrast, the other options describe conditions or misconceptions that do not accurately represent Type 2 diabetes. While Type 2 diabetes can develop in children, it is more commonly diagnosed in adults and associated with factors such as obesity and sedentary lifestyle. The statement that it only affects the pancreas overlooks the systemic nature of the disease, as it impacts various organs and bodily functions related to glucose metabolism. Lastly, complete loss of insulin production characterizes Type 1 diabetes, not Type 2, where some insulin production may still occur, albeit inefficiently due to the resistance developed by the cells.
