I wonder if anyone else has encountered this. We have had basal reductions before - but 50% in one night! DD, 13yo, had a lowish carb dinner and (50.4)promptly went low. We have a cgms so we gave juice thinking "oh bolus/basal out of whack - must fix that or make sure we have similar carb count dinner tomorrow". DD kept going low 2.8 (50.4) to 3.3 (59.4) for 5 hours. she had well over 120 grams of carb to keep her there and a 50% basal reduction for the whole time. She is still on 50% and has steadied at 5.4 (97.2). It is 1am here now. Any ideas? Has anyone encountered this before? Her usual dinner is around 70 grams carb. Is not vomiting, doesn't look ill, no temperature...no unusual exercise today, no stress - happy.....????? Absolutely nothing out of the ordinary.. other than the lower carb dinner (and she has had twice the amount of carb - uncovered - that she normally has!
