I had an experience today that more or less puzzled me. Yesterday,Tuesday, I consumed 31 grams of carbohydrates. Today my total carbs for breakfast and lunch came to 13 grams of carbs. I took 50 mg of prednisone at 3:30 AM and 50 at 8:30 AM. I was amazed that after lunch my bg was well over 200 in spite of my negligible carb intake whereas the day before after lunch my bg was 131. I also had targeted chemo therapy in the morning before lunch but I am not sure that was the cause.

I am leaning toward the prednisone being the culprit and I am not scheduled to be taking it again any time soon, so it may be a one time episode. I was wondering if anyone has ever had a similar experience.

Yes, high dose corticosteroids are a known cause of elevated blood sugars.

I've nursed quite a few severe asthmatics in my time who've wound up as diabetic as well due to their need for high dose prednisone.

I hope the drugs do a good job for you.

ETA: As you say, since the predisone is not a regular thing, you have nothing to worry about.

There is a long list of things that can effect blood sugar readings...some 30 or so when reader comments were added. Stress is a big one, often overlooked. You had chemo earlier? Might assume that is stressful either physically or mentally?

Janet, thank you for the link. There was some good information there, especially the part on exercise. I have been putting that off for one reason or another but now I am going to at least start walking or spend some time on the Nordic Trak.

Rosebud, thank for confirming my thoughts on prednisone. I had a dye-contrast CT and because of past experiences with the contrast they now pre-medicate me with prednisone. My experiences with prednisone have been terrible. Last night I hardly slept at all, a few catnaps, and I guess I can thank the prednisone for that.

Looking back on my records I have lost 9 pounds since 9/14. So, maybe I will get my BG numbers down in the next few months. Right now the doctor is saying diet and exercise and that is what I am going to do.

Thanks to all for the information.
