I am posting at this time of night because I am facing another night of practically no sleep and testing my daughter's bgs throughout. The period of extreme highs (20 plus) continued during our holiday last week and I was at my wits end. In the end I increased her basal by 100% and tinkered with her carb ratios and saw some better results towards the end. On Wednesday all her pump settings were changed properly by the nurse to accommodate the increased dosage and the next day she had great readings... Then wham! Hypo at 2am this mornings and numerous hypos throughout the day. I have just had to wake her to give her some glucose as she is hypo again. I have now reduced her basal by 50% and am waiting to test again. I have no idea what is happening and I am frustrated and exhausted. Is it possible that her increased insulin requirement was only temporary (albeit it lasted about 2 weeks) and she is now going to come back down to needing less again? I have no idea and feel completely fed up. Can anyone give me a clue what might be going on?
