Fasting BC and A1C

[doctordun]

During the day I take Glyburide and generally keep my BC around 110 average. My fasting BC is in the high 120's up to 140. My last A1C was 5.8 which correlates to a BC of 129. I believe my liver is a little wacky and working overtime at night.
My doctor was pleased at my A1C and didn't see any reason to change or add medication.

According the Dr. Berstein's books, my A1C is bad. What is the general consesus on this and are there any other accredited resources on A1C readings?

In other words, should I worry about my fasting BC?

Your A1c is great. From what I've read sustained levels over 140 are when the damage starts. Keep up the good wok & keep testing :D

DoctorDun,

You sound similar to me, although I only take Metformin. I have constantly elevated morning blood sugar readings, but the rest of the day is fine. My HbA1c is 6.2%, which corresponds to an average blood sugar of over 140. My morning readings average 120 mg/dl and my preprandial averages are 100 and 110 mg/dL respectively. I have to conclude that at least in my case, the HbA1c not necessarily inaccurate.

As to your current situation, I would agree with morrisma, keeping below 140 mg/dL keeps complications at bay, and that an HbA1c of 5.8% represents good control. On the other side, constantly elevated levels mean that you are constantly at the edge of slipping out of control. Personally, I would prefer to have my morning levels below 100 mg/dL and to always feel that I am well within the limits of control.

Since you are taking glyburide, it is possible that you are overproducing insulin at night, going low and overcompensating in the morning (Symogi effect). If you are taking a dose in the evening, you might move the dose to earlier in the day or skip the dose and see if that helps. Perhaps you can discuss this with your dr at your next appt.

I take a dose before breakfast and another before supper. Typically, I'm getting high bc by late in the afternoon. I take the glyburide and it seems to bring me back into control. I take a small dose, only 1.25mg.

Hey, sounds like you might need another med to help you use the insulin your body produces. If your doc says no keep asking.:eek:
