Type 2 Diabetes (T2D) is by far the most common type of diabetes. People with T2D either don’t make enough insulin or make insulin that the body can not use properly. The cells in the body become resistant to insulin, making a greater amount of insulin necessary to keep blood glucose levels within a normal range. Eventually, the pancreas can wear out from producing extra insulin, and it may start making less and less. T2D can usually be managed through diet, exercise, and self-monitoring blood glucose, at least in the first few years following diagnosis. However, T2D is a progressive condition, and most people will need to take tablets and/or inject insulin after living with it for five to 10 years.
