Thank you everyone yes endo called today said low a1c was probably caused by meds taken and from surgerys I've had or from the infection I had but the meds I have been on raise my bg so I asked her how that could be and she said with everything in combination and last a1c done after last surgery basically right now it was a dirty a1c reading until I'm over my problems won't be correct bg monitor I wore last weak still pending but good news is will be going on pump next month yeah that should help a lot she says so I'm looking forward to it

You must have had plenty of low BG during the day. It is still possible to have a lower A1C with occasional high BG reading during the day. or example, you could be over 300 25 percent of the day (when you are testing) but lower during other times, maybe overnight etc. Still not good to have too many readings over 300, but the lower times during the day bring your A1C down. Try to vary the time of the day you test, don't test the same time every day. You A1C is more like an average, although that is a very simply way to explain the A1C.

There are a couple of variables: you're having lows when you're not aware of it; the A1c is an average over three months and perhaps you've only been having the highs recently. The results from the glucose monitor are going to give you the best information. ~Lynn @Glucerna

The A1c is an average. The only way to get rid of the 300's is to greatly reduce your carb intake. Eat all you want of protein, fat and veggies; but, cut the carbs.

Moe. The advice you are giving DD is fine however, I think that that was not the question DD had.

He had high BG levels yet had lowered A1c. His question in essence was how can one have a high BGs yet a lowered A1c?

Howdy DD

My late wife "Jem" frequently had Blood Glucose (BG) levels above 300 mg/dl due to her needing to take occasional cortisone shots or pills. Yet one of those times when she was having an episode like that her A1c was shown to be in the low 6s. The diabetes nurse assigned to her from her heart clinic was puzzled by this since she knew Jem's daily BG was so very high since I sent her BG readings to her diabetes nurse and her endo every week by email.

It was puzzling until someone pointed out that an A1c is an average of one's BGs for 24 hrs a day for 90 days. That would include any hypos she might be having. We just happened to be testing her BG at the times she was high, and not when she was having the hypos (usually late at night when we were sleeping) Of course she would feel the hypo and scarf down any high carb food she could get her hands on and so she't go back high again.

Her A1c in the 6s made sense to me when explained that way.

Something like this may be going on with you as well, DD.

God's best

So sorry to hear that, I won't let doctors give me cortisone shots , refuse them every time because they do the same thing to me.

My jem needed the cortisone shots or the prednisone pills due to her Lupis (SLE) and RA "flares". She was allergic to the biologics and she was in such pain when she had a flare that those were the only options abailable to her to reduce the pain. I hated to see her suffering like she did when she flared.
