I hae been taking weekly readings of my fasting BG since October 2008 when I was put on 2x2 500mg metformin. About a month ago I changed to glucophage XR 500 mg one tab with dinner (because of the nauseous side effect). My monthly average readings are as follows:
Month Average Value
Jan-09 5.45
Dec-08 4.88
Nov-08 5.31
Oct-08 8.02
I did all necessary blood and urine tests yesterday. This afternoon I got the news from the lab that all the results are excellent except my HBA1c which is 7.6. How is this possible? Theoretically my HBA1c should be 5.54.I am told the GP has therefore asked me to increase the glucophage dosage to 2 tabs a day. I recorded 4.6 before the lab test. Could someone help explain all this to me please.
