4 months back my hba1c = 13 % fasting sugar = 153,pp = 228 mg/dl, tsh = 10.451 µIU/mL, c - peptide = 1.14 ng/mL. Started using thyronorm 50mcg, metformin 500 mg twice daily. Now my hba1c is 6.3%, fasting 106, pp 177 mg/dl Tsh = 5.76 C-peptide 0.99 Should I continue to use to thyronorm and metformin same dosage. How can I further reduce my hba1c and completely bring my sugar level to normal. Will my c-peptide levels decrease overthe time and nedd to take insulin in future ?
