When Stress Takes a Toll ( Diabetes )
Can stress cause type 2 diabetes? There has been some research on whether stress is a direct cause of the disease, but results were inconclusive. Other research has shown, however, that stress can elevate blood glucose levels. In some people, stress hormones directly affect blood glucose levels. In others, stress takes an indirect toll, leading people to eat more and be less active, which can also raise blood glucose levels. We know this is true for people who already have diabetes. So it seems likely that if your blood glucose levels are already higher than normal (but not yet high enough to have diabetes), stress could raise your levels to the point that you do have the disease.
So the stress of a serious life event, such as the death of a loved one or the loss of a job, could play a part in the development of diabetes. Keep in mind, however, that you are likely to develop diabetes anyway as your insulin resistance increased or insulin production decreased.
