Hi, has anybody experienced days when their child is CONSTANTLY very high (14 - 21) and no ammount of increased insulin will bring them down? We travelled home from holiday in Florida on Sunday and her sugar levels have been high ever since. She uses an omnipod and yesterday her nurse re set all her settings to significantly increase her insulin thinking it may be the end of her honeymoon period. This has made no difference and even the nurse has admitted she doesn't know what is causing it. She does not appear to be unwell so I can't put it down to that and, anyway extra insulin would bring her level down if that was the cause. Her control is normally very good so she is really stressed about this and so am I. Does anybody have any ideas what may be causing this??
