Why does my sugar go from 111 before breakfast to 200 after? I have type one diabetes and I'm on a pump. After breakfast my blood sugar always goes high. I eat only 4g of carbs every morning. I put Stevia in my coffee with 2 tablespoons of half and half.
Caffeine can sometimes cause blood glucose levels to go up, even if you are not eating. We don’t completely understand this phenomenon, but we think it might be related to how caffeine affects catecholamines in the body. When you are on a pump it is complicated, because a number of other things could be causing the higher blood glucose levels as well, such as a basal rate that is too low, dawn phenomenon, lows overnight, etc. Believe it or not, we sometimes have patients take a small amount of insulin to cover their coffee in the morning. Talk to your endocrinologist or diabetes educator to see if this is what they would recommend for you. Taking detailed food and blood glucose logs to your diabetes team for review will help to identify and solve this particular issue more easily.
