Actually normal glucose should be 80-120…..

First of all what did she eat? Some foods give an instant sugar…..some are a longer lasting….

Make sure you have her calibrate her meter…then try again…

Make sure she documents what her levels are and the time….It seems a little late for dinner…did you snack before or consume any alchol?

*** Potatos always sent me over the edge!!!
****A good way to help lower that level would be to take a walk after dinner

***Since you didn’t mention insulin…I am going to asume that the dr is intending to attempt a diet control…..Make sure you write down everything she is eating and the time, the level before and after meals…..You will be able to tell what foods she needs to avoid…I wouldn’t worry to much because the level is going down…therefore her body is processing the sugar…its a good sign
