I was one of those who said..."I am so fortunate, I still FEEL my low blood sugars." Well, I decided to buy (read, out of pocket) a box of sensors to make sure what was happening, especially at night. Of course, wearing the sensor made me test constantly...so, I have gotten a pretty good sense of what my blood sugars are doing round the clock. Little did I know...I am dropping into the 50's WITHOUT any indication that my blood sugar is low. I woke up this a.m. at 49mg/dl (per meter) and felt totally normal. I proceed to check w/ both of my meters...yes, I am low! I was scared to death...I think I have been sleeping through these! I was under the false impression that I still had dawn phenomenon! I do not..but, my pump settings were set for increase before rising. My dawn seems to be after I get up...through breakfast. I had this low AFTER reducing my 3 a.m. to breakfast basal rates! The diluted point I wanted to make, was that I wonder how many of us experience these types of lows, that never get noticed? How did you find out that you had hypoglycemic unawareness (HU)? What do you do to identify when you are having one? When did your doctor identify that you had it?
