Hello, what an impressive HbA1c for a type 2 diabetic! You haven t mentioned the exact timing of self-measurement so I could not comment with confidence on your glucose value but 140 is not a high value anyway. 140 would be high if it was a fasting one. If it is 1 hour after breakfast then it s OK. If it is 2 hours after breakfast it is still OK but also indicative of your diabetic situation. Actually your values are so normal that I m ready to begin doubting about the diagnosis! Any kind of inflammation affects glucose regulation. Even a painful tooth or a slight injury that got inflammed will cause increased blood glucose levels. The effect on glucose will depend on the severity of diabetes and the severity of inflammation. A well controlled patient will respond much better than a neglected diabetic patient. A 10-15% increment is a fair estimation for you case. I hope I ve shed some light on your situation. If you need further clarifications on the subject, I ll be glad to provide them for you. Keep up the good work on your glucose regulation! Kind Regards!
