For about two months now my blood sugar levels have been rising overnight from being 6.6 at bedtime to being as high as 23.0 at 8.00 am the next day. I am Type 1 and have been for over 40 years. I am now treated with insulin pump and have contacted my consultant about this but nothing seems to work. I have done sugar levels throughout the night and seen the levels rise from 2.00 a..m onwards. Even though I treat any sugar level of 12.0 or above with insulin the levels never go down overnight but continue to rise. I have changed basal levels on my pump but that hasn't helped either. I am very worried about this and have never experienced anything like it before. I feel so weak and sick a.m sometimes that I am unable to eat anything until about 11.00 am when my sugar levels have gone back to normal. I am very worried about this lack of control overnight and high sugar levels as I already have sight issues and only have sight in one eye. What is the problem? What can I do about it?
