The difference, however,  is that dawn phenomenon is not caused by hypoglycemia, but by a random release of the triggering hormones. For the Somoygi effect to occur, your blood sugars typically need to drop to low levels first to trigger the liver’s output of glucose. The Dawn phenomenon is tricky, since the hormone fluctuation could happen even when there is no apparent reason. The sugars may just rise.
