Re: [IP] Bolus Wizard


I don't think you mentioned in your original post that you went past 
that message.  That explains why the pump gave you insulin even though 
you were still low.  There are several reasons why this "reverse 
correction" may not be correct.  For one, it just reverses the 
correction formula by subtracting insulin, instead of adding.  I have 
told MiniMed that this doesn't work for me and asked them to customize 
it.  Maybe if you and others also speak to them about this, they will be 
more likely to change.

In the meantime, however, the way I work around it is as we all do with 
diabetes:  guesstimate!  I double the amount that the pump has 
subtracted and manually decrease the bolus amount.  Also, I wait until 
my blood sugar has actually gone up into my normal range before I 
bolus.  If you originally went low because you had too much IOB, then 
that insulin may still be acting and that would also adversely affect 
the formula's calculations.
