Fasting blood glucose higher than post-prandial

[growing]

Today, my FBS and PPBS were 109 and 97 mg/dl, respectively. This is a usual trend with me.
Any comment?

Interesting. Isn't the PPBS usually more than the FBS?

There is something called the post prandial dip, but it's usually associated with consumption of a large meal, rather than a normal meal.

I have this trend since quite a few years. I doubt, it could be related to sleep apnea-caused disturbed metabolism during the night.
Does any body have this experience? Posts with any kind of insight over the matter would be appreciated.

Do you take any diabetes medications? Insulin? What are you eating, and what is your exercise level? There are so many things that influence you blood sugar levels, including what meter you are using, and it's range of error. I'm a former medical technologist. While these readings are not so close as to be insignificant, they are pretty good readings, so I wouldn't be too concerned about them.

Hi

My blood sugar is always higher fasting and i have been told that it is down to Dawn phenomenon don't really understand it much but some people have much higher levels first thing in the morning due to Hormones and glucose levels getting the body ready for the day, my diabetic nurse tells me it's not a problem providing my HbA1c is ok

Stillo is correct. Are you diabetic or insulin resistant? Some people say this is more common if following a low carb diet, the body has to push to make a little insulin in the morning, but the numbers are low enough not to be concerned.

Yes, my numbers are consistently low but always FBS is higher than PPBS. I do not take insulin or any pill for diabetes. I take no pill. Nothing except the HOSE.
I hope this anomaly should correct itself after I reach and maintain a significantly low AHI range: hopefully, very close to zero or a zero.

What do you say?

That was my point in posting the A1c controversy---the only time I did not home test was during the night, so I wondered if my severe OSA had created a metabolic cascade during the night, so my A1c runs much higher than any BG or home test. Does anyone have a clue as to how long of treated OSA, before mild (not full-blown diabetic) insulin resistance resolves?

Yes, how long does it take to reach a normalcy and what should be the effective lowest of the AHI range?

Kitatonic, sorry, but how long have you been on this aberrant A1C range? I would like to compare our night time BS excursion.

CPAP alone will not resolve insulin resistance. A carb controlled diet is the key. See Dr. Richard Bernstein's Diabetes Solution. Good info here: http://www.phlaunt.com/diabetes/index.php

Growing, the aberrant A1c has just been noted this past year, but like Jan notes, this is decades of a "healthy low-fat, high unrefined carb diet". From Jan's link, my A1c should be 4.6, and should have come down considerably after following a low carb diet the last 7 months. My OSA AHI has averaged 0.2 for the last 17 months, so that obviously is not the sole culprit. From the stories on Jan's link, I think we should stick to the low carb diet and eventually the A1c and the ALT (liver enzyme) will follow. Growing, does your ALT (possibly fatty liver associated with insulin resistance) run slightly high?

[growing]

OK. I will do this ALT thing and tell you. Never done before.

[Kitatonic]

Growing, my ALT is considered "normal" at 60, but in fact for a non-drinking, petite woman, it should be around 20. For over a decade, no one ever suspected OSA-induced insulin resistance leading to a mildly fatty liver. Read QuietMorning's post on OSA & liver which as an excellent link.

I have found somewhere that every unit increase of AHI increases my IR by about 0.5%. I can assume somewhat similar trend in liver injury and other parameters. However, then, I can also expect similar decrease if my AHI is decreased, as a corollary.
Now, your AHI is already 0.2, obviously, better than many many 'normal' individuals. This means that you are already in the phase of restoration. Congrats.
But, how long have you been on 0.2 AHI?
