Hi,
my blood sugars been quite high over the last few weeks when i wake up. At bedtime they are about normal. Can anyone explain please?
Hi vedka
I am T1, 5 years and keep my sugars pretty well controlled (last HBA1C 6.5). I just had the same weird week of morning highs as well. Totally inexplicable, no change in anything, no illness etc.
I play with my lantus splits with exercise etc, and I just did a few things this week that brought my sugars under control again.
First one was cut out any food intake after about 6:30 or 7pm. That reduces one variable. Then I know the bedtime BSL will be 'stable', as Rapide should be through my system and food should generally all be digested.
Second one was up the split of lantus. Usually I am 10units at night, 4 in the morning. I went to 14 at night and an extra 2 in the morning for about 2 days, then went back to the usual 10/4 split. While I dropped a little lower than I would like on those 2 days, my BSL is back down and morning highs aren't occurring.
I can't give you a medical or physiological explanation, other than maybe residual late night food digestion that continues after Rapide has cleared the system, and the lantus can't cover the sugars adequately.
I did a few 2am BSL tests to eliminate night time hypos just to check.
Morning effect seems to become more prominent every now and again, and I can wake high, exercise intensely without breakfast and stay high (almost like the BSL is more resistant to insulin for some strange reason). But once I bring the sugars under control again morning effect seems to disappear again.
Aahhh the joys of being completely in the dark about your own bodies machinations!!
Hope this helps in a small way.
