Feeling a bit 'off' after eating anything with sugar in it

Hi Poppie/Samantha, and welcome to the Diabetes Forum. I'm not really sure but I'll tell you what I think from my experience and I'm not a doctor. Pred raises blood sugar and most doctors warn their patients about this when they're on it long term and usually monitor their blood sugar because of it.

Sometimes feeling off could be high blood sugar or low blood sugar. You might be rebounding. That is, maybe the food with sugar is causing really high blood sugar and you're feeling off because of it, or, maybe you're feeling off when your blood sugar is coming down. It might be yo-yo-ing, but without testing it at that time, it's only a guess.

If you get a tired and lethargic feeling after eating food with a lot of carbs, it's because your blood sugar went really high and then dropped. Eventually, it evens out.

It would be best if you had a blood sugar meter to measure your blood sugar when you're feeling like this. In the meantime, while you're tapering down on the pred, try to eat lower carb to counteract what the pred does to the blood sugar.

This would help keep your blood sugar to more normal levels if it's getting too high. That would mean cutting down on food made with flour, any kind of flour (wheat, corn, oat, etc.), potatoes and of course anything with sugar or honey. It might help to eat smaller meals more frequently throughout the day. More like snacks than meals actually.

Fresh vegetables, salads, salad-type food (celery, radishes, olives, cucumbers), some cheese, nuts, unsweetened yogurt, peanut butter, leafy greens, chicken, fish, (meat), bell peppers...

Lots of people have to be on steroids for one reason or another. I was for a short time because of bursitis and my blood sugar was elevated and came down to my usual levels. Other people have had very long-term steroid use for other reasons and it's known that in rare instances it can cause diabetes but I think generally most patients go back to normal. This is why their doctors monitor their blood sugar.
