Hi there
@suki2016
welcome to the forum !
from the description you have given in your topic--
I would expect your daughter is on an MDI regime -- that is a long acting insulin ( lantus , tresiba , levemir )
and a fast acting ( novorapid , novolog )
if so , there will hopefully be patterns to look at in blood sugar readings.
has the low blood sugar happened withing 3-4 hours after a meal ??
are you getting low blood sugar readings in the middle of the night ??
it is difficult from your post to be sure what you are asking ?
if I read correctly -- YES -- if i have active fast acting insulin still on board( within that 4 hour post meal injection ) and I test below 4.0 -- then that is a hypo brought on by the fast acting insulin .
