A1C three months ago from doc’s lab was 5.9, I tested last month and it was 5.2. today is 5.8. Can anyone help me understand why numbers would vary? I understand that glucose attaches to hemoglobin and that’s how a1c is measured and am trying and hoping to get these numbers down. I have increased my exercise….currently doing yoga and recumbent bike for 30 minutes day up to 6 miles. Fairly active with walking on property and doing yardwork. Diet not too bad, but eat too much sugar. Anything else I can do?
