Thanks for info. Will follow up with Dr.
This would be something your mom's doctor or endo would decide based on a number of factors. It is possible for Type 2's to change to other oral meds or increase doses to control blood sugars. But if she has been Type 2 for many years, been tried on different meds and still has high blood sugars there is a possibility she is no longer producing enough of her own insulin and may have to be put on insulin. A test called a c-peptide could determine how much insulin she is still making, but her doctor would know her history as I described above and have a good idea if insulin is now called for.
