Ksdm,
I am type ll diabetic due to therapeutic long term, high dosed steroids. I did some looking into my meds because the blood sugar #s weren't really going down and at times increased after meds. I researched each med and asked its affect in blood sugar. I was shocked at the number of meds I am on that increase sugars. It's a viscious cycle.
Ck into your husband's meds to see if your concerns are validated.
