It's important to know the nadir for a couple of different reasons. The first reason is safety: Since the nadir is the point in the cycle when the BG is at its lowest, knowing the BG number at that point tells you if the cat is in numbers that are safe, or if he's going hypoglycemic. Hypos can happen at any point in the cycle, but if a cat hits nadir at +6, and a person only tests at +3 and +8, they might think that the cat is doing fine, when really he's hitting hypo numbers every day, just not when he's being tested. If that goes undetected enough times, or severely enough, it can kill the cat. Conversely, if you assume a cat is going lower, but aren't testing at the right time, he could be sitting in numbers that are too high every day, and that's bad too.
Second, knowing how much change there is between the pre-shot number and the nadir tells you if the dose is working or not. For cats in higher numbers than Teddy gets, they would want a drop of about 50% for a "good" cycle. As the pre-shot numbers get lower, you don't need or want that much of a drop. So the difference between the pre-shot and the nadir can tell you if the dose needs to be increased or decreased or maintained.
Finally (well, there might be more, but this is the last one I can think of right now), if you know the nadir, you don't have to test as many times/day. This one does depend on how consistently your kitty responds to insulin though. If a cat is inconsistent and bouncy, this last reason doesn't apply because on kitties like that, their nadir will move around, and they can sometimes drop early or late in the cycle, so those kitties need to be tested more often anyway. But if you have a cat like Sam (my cat), he gets pretty consistent responses, so I only need to test him around his nadir most of the time. I just test to keep an eye on how effective a dose is. Sometimes I'm a little before or after his nadir, but I get as close to it as I can. Also, his nadir doesn't move around very much, so that helps too.
Oh this is great information and you explained it so well. Thank you!
Oh wow a cat could be going hypo every day without someone knowing it. Well if a cat gets in the hypo numbers and by the time the cat gets tested his numbers are higher...does it hurt the cat? I would never want this to happened, but I'm just trying to understand....I thought it only hurt the cat if the cat didn't go back up on his own?
And yes that makes complete sense about the dosing.
I'm going to check out your kitty's spreadsheet. That makes sense too. I need to do a lot more testing to figure out teddy still.
Thank you for all of your help!!!!!!! It's so nice to be understanding all this stuff better now!!!
