Blood sugar levels

Hi Doc. I'm a 58yr old diabetic, trying to eat as healthy as possible. Monitor sugar levels twice a day for past 2/3 months - reading at bedtime (6.6 - 8.5), then again before breakfast (7.7 - 8.9). Most of the time my blood sugar levels increase during sleep?

Good fasting readings should run between 4 to 7, and a reading done 2 hours after the first bite of food(breakfast, lunch and supper) should be less than 10, as this will mean an HbA1c(3 month glucose average test) of less than 7%. To have a normal HbA1c of 4-6% would mean having fasting readings between 4-6 and post meal readings less than 8. For elderly patients the targets would be a fasting level 4-7, and post-meal levels less than 12, with a major emphasis of avoiding low glucose levels. As glucose targets are individualized, you will need to ask your doctor what he wants you to try and achieve . Levels can increase during the night, as the glucose originates from your liver as opposed to what you have eaten. Glucose from your liver is under the influence of hormones like cortisol and adrenaline, and therefore if these hormones are higher during the night(poor sleep, sleep apnoea), then the glucose levels can go up during the night
