From Dallas, Texas USA:

What is the difference between having a slightly elevated blood glucose in the morning for a couple of hours before waking (130-160) (as a result of dawn phenomenon or rebounding from a hypo) and having an elevated blood glucose for the two hours post prandial? Wouldn't the effect on HBA1c be the same, especially since you medicate on waking anyway?


HgbA1C [glycohemoglobin] reflects average blood sugar over the previous 2 - 3 months. It does not give you any information regarding the pattern of blood sugar levels. The difference between an elevated blood sugar before breakfast and after breakfast is that you may need to change a different insulin during the day to lower the blood sugar.
