It's not just your boss or your workload that may be affecting your diabetes control. Blood glucose also seems to be affected by when you work.

This study shows that our bodies react differently to food intake at different times. Night shift workers appear to have impaired glucose tolerance, putting them at an increased risk of type 2 diabetes.

"It is surprising that just a single night shift can significantly impair glucose tolerance and increase insulin levels," lead author Christopher Morris, PhD, of the Program of the Division of Sleep medicine at Brigham & Women's Hospital and Harvard Medical School, said. "These findings are important because they demonstrate, under highly-controlled lab conditions, that acute exposure to night work impairs glucose tolerance. Chronic impaired glucose tolerance is likely to lead to type 2 diabetes."

Are you one of the millions of Americans who works nights? It would make sense then to account for this by altering what is eaten at this time or to perhaps ask your healthcare provider about a medication change. Knowledge is power, so hopefully this information will give you more clarity about your diabetes control if you are indeed working a night shift.
