Trying to figure this out. I’ve had very predictable blood glucose patterns for two months. The last two days it’s as if a switch was flipped. Higher morning sugars, dawn effect lasting longer into the late morning, higher glucose elevations with food, and longer time for the glucose to come down after eating. Haven’t changed anything in my daily routine except I find myself eating less to try and keep the glucose elevations under 140. What would cause the glucose to go from a very typical post-prandial up and down pattern to just sitting around 120-130. I've verified with finger sticks. I can't imagine the Dawn effect would last all day. Would moving the clock back an hour cause this?
