High: High 600's Low: 47
Recent ranges avg: 120's - 70's
The abnormal low was due to moving daughter into dorm all day and not taking any meal breaks til later in the evening. doh!

I'm a Type 2
When I was diagnosed it was 800+ ( I don't remember the exact # but remember them telling me they didn't understand how I could function at that level…your the doc you tell me) my lowest ever was a 13, taken by my husband after he found me unconscious and barely breathing, at that time we lived in a small town just a block from the fire station which housed the ambulance, the ER had told him another 5 min, if that, I'd have been dead had he not found me when he did. This was caused by a switch in insulin to a fast acting and the dosage prescribed was too much.

Whenever they switch my insulin I start off with a tiny amount of what they suggest and work my way up. It seems like most doctors are a little too liberal with their dosing amounts with insulin. I can deal with highs much better than lows.

Unconscious(20?) to 490, before the pump and cgms. Lowest I ever got on the meter was about 22.

Now 56 to 350 with the pump. Highs are only when I do something dumb though. Same with lows, still learning the pump (only about a month with it)

Was about 600 when diagnosed.

I'm a type 1. The highest I ever got was when I was first diagnosed which was over 500. The lowest I have been was 59. Now I fluctuate sometimes between 300 and 79.

my lowest was around the 60's.. was a few yrs ago when I had this though.. My highest was somehere over 500. i have no idea exactly though as my meter at the time only stated HI for readings over 500 and not the exact number.. I had this happen a few times.

From 1945-198? before I had a glucometer, I have no idea what my blood glucose numbers were.

After I had a glucometer I had some readings, many years ago that read HI and others that read LO and I was unconscious.

Now that I have my pumping under control I am doing much better.

Yesterday I was 79-130, the day before I was 82-125. Other days befor that I was 69-136, 78-115, 75-131, and 62-116. Pumps are great!!!

When diagnosed, tested in at a hefty 1500. Rehab docs wondered HOW I could still be awake and talking!

Lowest has been 38.

Ran in the high 300's to the low 600's for about 3 years straight.

In ICU for ketoacidosis and kidney infection, when admitted, near shock, almost lost the battle that day.

When I was a public health nurse on an Indian reservation we had a 12 year old girl who was running a 2500 blood sugar when she was diagnosed. She was still awake altho not really alert. The doctors at first thought she was drunk until they did a blood sugar. Shows you can always jump to conclusions.

I'm type 1 so forgetting my insulin or an infection can be a bit more dramatic than it seems to be for a type 2. The highest I've been (that I know the number for) is 508 (didn't take enough insulin, but was also very sick that night. It was frightening!). The lowest was right around 30. I can't remember if it ever dipped below that. These are extremes, of course. I'm usually pretty good!

My highest was somewhere in the 200's after eating and 48 was my lowest that I recorded on a meter… With me one never knows 'how low can she go' because I can't think when it gets that low and I forget to test, I just eat.

at the beginning her meter would just say HIGH and the lowest was 11… my computer crashed the other day glad to be back!!

i clocked in at 242 two hours after eating, i think the day before yesterday. highest i've ever been. about two years ago i had some extreme lows, the lowest being 35,this went on and off for about a week. this also would be after eating. i was on no medication for diabetes and the doctor told me through his nurse, to eat more. so i have!
