A1c a control marker. A1c is a long term marker for glucose levels in the body. It will go up to higher levels when the blood sugar levels are above recomended levels and declines when you keep your sugars in a healthy range. Since the sugar level can go up or down dramaticly over less than hour, A1c is a better overall gage of long term control than your test diary (& you can't fudge the value).
They don't. They need to get hga1c to 6.0-7.0 without getting low blood sugars!
Probably not... Your body has an incredible ability to regulate blood sugar levels and when this ability is intact, excess carbs will be converted and stored as fat, thus should not raise your a1c. Once the ability is diseased, the excess carbs/sugar stay as sugar, thus higher blood sugar in diabetic, and will raise your a1c over time. Moderation is key. Live a well-balance life. Live long. Consult doc. Good luck.
No. Inappropriate glucose metabolism and Insulin deficiency or resistance will increase the intracellular red blood cell glucose concentration.
Probably not. This is below the threshold of diabetes, but it is only one test for diagnosis.
