I buy it, totally. Not that sometimes my kid's diabetes may vary from some other kid's because I don't do as good a job or don't understand insulin or whatever. But I totally buy that two people who seem similar and who do exactly the same thing for a week can get vastly different results from their bodies. Over three years here, I've read many posts with a smirk. Yeah, right. Usually these were the posts by members with kids who could stay in range 80% of the time, or by folks who could calculate I:C ratios so that 1:20 vs. 1:21 mattered to them. Folks who claimed to be able to feed their kids processed carbs in bulk four times a day and still get an A1C of 6.8 with no serious lows or highs, or people who could bolus off a CGMS and be sure of its accuracy. I figured they were, well, glossing things over a bit. It's gone the other way, too. I'll read a post by someone trying hard and "doing all the right things" and still the A1C is 12 or 13 and I'll think -- naw, she must be doing something wrong. But I'm here enough that I see more and more posts from all kinds of people. And, yeah, sometimes no doubt the perfect control diabetic is lying about the perfection, and sometimes the way outlier diabetic is there because she doesn't bolus. But I sincerely, truly believe after all I've read that many, many times there are wide, wide variations in the way diabetes treats any given person's body. I'm told now that "type 1 diabetes" is probably more of an umbrella for a number of different types. I've also seen enough to know that human bodies are very individualized things, they aren't math equations, they are far too complicated for micro-predictions. So, to take the topic over to "hot", I truly believe that no two diabetics have the same physiology regarding blood glucose, insulin use, ketones, etc.
