A1C levels do not tell the whole story. It is an average of blood sugar levels over the past several weeks. It does not indicate what variations are involved in the "average". There is no standard deviation stated with an A1C. Self monitoring is also limited as it depends heavily upon WHEN testing is performed and frequency.

The BEST indicator in MY opinion of what is really going on is from a device used by a few type 1 diabetics that does continual monitoring, every 5 minutes or 15 minutes, etc.

All other "tests" are either an average or at a single point in time. Maybe some day, the cost of continuous monitoring will be low enough that everyone with diabetes can use it for at least one week, periodically, to get a true picture of the fluctuations.

A low A1C is not always an indication that hypoglycemia episodes is the reason. Some type 2 diabetics do regain control by body function alone. This happens mostly in people that have extreme weight loss or for some other reason that changes their metabolism.
