You are probably dealing with three things here.
- She is leaving her late honeymoon phase.
- She is experiencing hormonal fluctuation
- She is a teen
A very important thing that is probably happening is that she is
finally leaving her late honeymoon phase. Lots of us have a long term
honeymoon that lasts up to 3 years. If she has been diabetic for 2
years then and she is leaving a longer phase, her insulin needs will rise.
Read Mad Evans's post. He give a classical example of this transition. On the 1st page of the thread he talks about how low his insulin needs are. On the 3rd he shares with us how his insulin needs have changed now that he left his honeymoon. http://juvenation.org/forums/t/455.aspx?PageIndex=3
Has she started menstruating? Hormonal changes will swing her insulin
needs up and down. Two days before I menstruate my basal insulin needs
rise 40%! Then lower them back the morning my period starts. This can
vary, other times my needs will drop by 40% if I choose to exercise
heavily the week before my period.
her behavior is pretty normal for a young girl diabetic, there is no
need to limit her until she gets back in line. The fact is that in the past she probably was able
to skip insulin doses without these highs! You probably never knew. And
really it didn't mater. But it does now, and that is something that you should talk with her about and help her come to terms with. Also talk with her about how her body needs the amount of insulin that it needs to function. This amount will rise, it will drop. Tell her that her numbers are not a measure of who she is or how good she is- the numbers are there to measure her needs.
You and her doctor need to help her find a new dose knowing these things I listed above.
Also a good reminder for her to repeat is "Food in mouth pump in hand."
