I am confused by my evening and next day morning numbers. I can go to bed at 120 or under and wake up the next morning between 140-160. Conversely, if I go to bed at 160 or higher, I wake up around 112-115. I still cannot figure out why this is transpiring. I was diagnosed in Nov 2011.
Sometimes if the body does not get enough food in the evening hours, the body may think it is starving and send messages to the liver to make more glucose overnight. This is what may be happening to you on the days when your blood glucose goes up overnight. Having a small higher protein snack, such as lowfat cheese sticks, or a half cup of lowfat cottage cheese, some peanut butter with a few saltines, or a half cup of lower calorie Greek yogurt, may help the liver produce less glucose overnight. The trick to snacking in the evening is not to eat too many carbs or too big a snack, particularly if you are trying to lose weight. If you find your blood glucose levels continue to be up and down overnight, even with a small snack, meeting with a dietitian who can do a detailed review of your eating habits may help.
