Customer Question

Doc had me on prednisone for inflammation (gout). After 3 days,he started me on 1000mg Metformin. My blood sugar was 122 and he said he wanted it at 100. It shot up to 550 and then dropped off to between 360 and 440. I felt TERRIBLE. I stopped the Metformin and my sugar fell to 225 but now it stays constant and won't go lower. The second day on Metformin, I started a steady post nasal drip that started building up like scabs inside my nose. Blowing makes my nose bleed. My nose is soooo sore !! What's going on here?

Welcome to JustAnswer Health...and thank you for your question. I am a verified Expert and am delighted to help you today. Metformin is not the problem....Prednisone causes the boby to metabolize sugar differently and can cause very high blood sugar levels. Once you stop taking it ( After several days) , your blood sugar should return to a more normal level.

I have been off the prednisone for quite some time. I KNOW the prednisone raises the sugar way high. That's why Doc put me on the Metformin The prednisone had plenty of time to metabolize before I stopped the Metformin but the numbers continued to be higher than usual and erratic. I also figured that since the steroids lower the body's immune system that was the reason I developed a sinus infection. It will not go away like in the past,however.

Steroid induced diabetes( in the absence of pre-existing diabetes) will usually resolve after the prednisone is stopped,however,in some cases it takes much longer, and in others it becomes a chronic problem.

The "borderline" case was pre-existing before the treatment for gout. ( I noticed, in my initial question,I left out a line. After my blood sugar stabilized at 225 (100 points higher than right before I started the prednisone) I went back on the Metformin to see if it would go back to 122 or lower as Doc wanted it at 100. It (blood sugar) began to rise again. Up to 365. After the second day is when my nose began to run..non-stop..especially after eating. Also,it didn't matter what I ate. A banana or apple or raw asparagus...anything ingested increased the flow that was sometimes bloody. Not heavy bleeding like an injury but light bloody streaks like a wound seeping after having scabbed over.

Prednisone is the likely culprit here because it causes thinning of the lining of the nose and makes it more likely to bleed.

I still don't know why my sugar went back up 200 points after going back on the Metformin !!

Expert:  CamilleRN replied 6 years ago.
Your sugar went up due to the prednisone... in the absence of the metformin it most assudedly would have been even higher.
Customer: replied 6 years ago.

You're not getting it !! The prednisone was out of my system. The Metformin was out of my system. Then ,after my sugar had stabilized at 225 (100 points higher than it was after the first 3 days of prednisone,when I started the Metformin) I went BACK on the Metformin and my blood sugar went BACK up !! So basically,It's like starting the Metformin without ever having been on prednisone, and my sugar went up instead of down.
