I'm new here and have a question. I've been diagnosed with T2 diabetes less than a year ago. I have a strong family history of diabetes on both side but used that to do what I could and would do to prevent it. I once had a reading of 69 and the doctor said that was almost too low. I was diagnosed with T2 after being on a heavy dose of prednisone for an extended period of time. I was weaned off it and my levels still stayed high. I'm back on the prednisone (30 mg daily) and test first thing in the morning because, to me, that is when I'll get the most normal reading. Tonight I've been reading and need to know if I should be taking my reading at different times during the day? My 14 day average is 122 today. If I take it after taking the prednisone the reading will be considerably higher obviously because of the prednisone. Unless I go completely bonkers and eat way too many simple carbs my readings don't go above 200 regardless of time of day now that I'm out of the hospital and moving more. Once I'm weaned off the prednisone I will go back to testing at various times just to make sure that everything is OK. I look forward to opinions on this and any research is even more appreciated. Before reading all this tonight I was not worried about what my readings were during the day as I have a good grasp on what to eat and when. I was on metformin 1000 mg but after my most recent hospitalization I'm off that and on Levemir (38 units) and Novolog (15 units with meals).

Check with your Dr as to when you should test. I was told to test 1st thing for sure before taking any meds. I also take prednisone right now, 20 mgs for RA. sometimes when its allergy season I have to take more.

Hi and welcome to DC. I was diagnosed after taking heavy doses of prednisone for 3years prior to being diagnosed. I am now on insulin 2 times a day. I think that since you are on insulin you should probally test various time throughout the day. I know prednisone help with keeping my blood sugar high. I will be glad when I can get off of them. Good luck and take care.

I want to thank you for your post because you taught me something today that I had not known before and never would have thought of. I check my sugars at least once daily if not twice. Im very well controlled and lucky at that. A lot of my family members had to take it before and after each meal.

I hope to you will post more as you learn so we can learn with you. I wish you well and have you in my prayers.

I have had to use prednisone for shoulders and get large doses at a time. I am T1 for 38 years. I check my sugar 8-10 times a day and now use a sensor (continuous glucose) — but when I take prednisone, I get 400+ readings and have a difficult time getting it down.

Just have to test and adjust insulin (more!).

Good Luck!

Hey Scott, I have to say that I love your profile name! LOL how appropriate.
I am sorry to hear that the prednisone does such a horrible number on your sugars. Wow....there has to be some alternative to this.

Unfortunately, predinsoe is one of those drugs that elevates our levels. Cortisone, niacin and others will do similar things. It becomes a game of balance with the need for the meds and the need for lower numbers.

Wow learned something new today, I was just put on predisone for my back, I have hernitaed discs that has been reallly bad this past week that took me out of work, and put me on percoset and predisone- which by the way is not working. On top of this I got epidural shots in my back this week, so as luck in my life would be my sugar has not dropped below 200. Now I did up the metformin and it got down to 113 yesterday.
But did not know predisone was one of the issues, learned something new today

Howdy Gem!

My bride "Jem" (Yes, that was my pet name for her) had Lupis (SLE) and RA (among other things) and because she was allergic to the newer meds to treat those "medical challenges" so she had to take prednisone. And of course it put her BG#s through the roof. It took about 4 mos of working closely with her Endo after she was weaned off Prednisone. (BG readings 4x/day email those readings to Endo 2x/wk), before her BG#s started to come close to normal. The Endo had Jem on 3 different insulins, long acting, Short acting and shorter acting (sliding scales on last 2 insulins). We got her down to the 100s with a lot of hard work.
