Hello. An
Hba1c of 6.6 means average blood glucose around 150. So reason for increased blood glucose values could be
1. You haven't followed dietary precautions
2. Not exercising in recent time
3. Omitting medication when you check for FBS PPBS
Next Steps
I would recommend you to strictly follow diet chart according to your weight, physical activity of 45-60 minutes per day. repeat FBS PPBS after 1-2 weeks
