When I’m taking dexamethasone, my blood sugar climbs. My endocrinologist doesn’t feel it’s necessary to treat it, because it’s only mildly elevated, as long as I watch what I eat. I have to stay away from starches & sugar. Sometimes that’s not so easy! We had cake at work, and boy did that do a number on my blood glucose.
What I do to lower my blood sugar is exercise. I walk a few miles, and my BG will go down as much as 50 mg/dL. If you’re able, get out and take a brisk walk. It will help. Tonight the first walk early in the evening lowered my BG from 230 to 197. The second walk brought it down to 147. It’s late, and I’m too tired to go again. :)
