Lowest - 1.2 mmol / l - 21 mg/dl - I was still able to function believe it or not
Highest - somewhere over the 30 mmol/l - 540 mg/dl range - but that was way back in my teen years - many moons ago :)

To the best of my recollection...

Highest - 560 or so
Lowest - 23 (Husband had to help me, and decided to give me a glucagon shot since, though I was conscious, I wasn't very coherent.)

It's been a VERY long time since I had a glucose level that high, and thankfully, didn't go into ketoacidosis, but did have moderate ketones. When it went that high, it was usually because I couldn't recall whether or not I took the insulin I calculated for a meal, so erred on the side of going higher, then feel asleep. (When something is done so frequently, like taking mealtime shots, it can be done - or not - without being consciously aware of it.) Now that I'm using a pump, I simply check its memory to see what I've done.

My endocrinologist at the time, said to drink at least 12 ozs of water every 30-60 minutes to flush out any ketones as quickly as possible, to stay awake and check my glucose whenever I got water, and if, after 2 hours my BGL (blood glucose leverl) didn't go down, to take half of the insulin I calculated previously, and continue to test for the next 2 hours, then take the rest of the insulin if needed. A pain, but, thankfully, I've never had to go to the emergency room for diabetes issues.

Not including diagnosis (not sure what my blood sugar was then), the lowest has been 1.2 mmol/L (21 mg/dl) and the highest has been 32.0 mmol/L (576 mg/dl), both of those were within my first year of diagnosis at age 9. I also swear I remember getting a 0.6 mmol/L (11 mg/dl) in high school when I was using the Dex. I was so curious I looked it up, and according to the Dex user's manual it does read that low, but I have trouble believing I was actually that low and coherent enough to remember it!

I've also gotten one or two LOs and HIs in my lifetime (too low or high for the meter to read), but the cutoff levels for those are different depending on which meter is used, so I don't know exactly how low or high they were.

Both of these times I was actually awake and talking!

My highest was 499( that was about a month or so ago) and my lowest was 63.My 11 year son grabbed a regular can of Pepsi because that 63 made him nervous.After I retested and it came up to around 100 he came over and gave me the biggest hug he could give.Moments like that make me cry.

Hi Tiera,
My highest was 551 and my lowest was 46 and thought I was going to kiss the floor, I was out shopping and left my emergency kit in the car, so I ran frantically into a store for orange juice. Cynthia
