I have been told repeatedly not to give insulin if the blood sugar is less than 200. So I thought I was doing the right thing by not giving any this morning.
When you are just starting out, the threshold on the Feline Health forum is 200 for new members. On Lantus Tight Regulation forum, the threshold is 150 for new members. At some point, learning to shoot low numbers is necessary. Since you can't get those PM numbers due to your schedule, I do not know when you might be data ready to shoot low numbers. for now, stick with the 'Do NOT shoot under 200 rule'.
Also, isn't it a good thing to not have to give any insulin?
Yes, but only if the BG numbers had stayed low, under 120. BG numbers for a non-diabetic cat, normal range is 40-120. If your cat always stayed in these low numbers, then no insulin would be required. If the numbers are higher than the 120, you need to be giving some insulin.
Doesn't it seem like her blood sugar is 250 and up often enough that 1 unit is either the right amount or even too small a dose?
Actually, I see the exact opposite. A dose that is too high, can cause higher BG numbers. The pattern I am seeing is bounce, bounce, bounce, dive, dive, skip. Starting 5/5 PM through 5/8 the pattern is low, skip, bounce, bounce, lower, equal, dive, skip. If the dose was the right amount, there would not be the constant bouncing, crash dive and need to skip the dose.
Do you see back on 4/18 when you were giving 2 units? See those low green numbers at +6? That is probably what is happening overnight, a dip to the low green numbers, the liver pumps out counter regulatory hormones and some glycogen to raise the numbers and then you bounce for two and a half days, dive and hit under the 200.
If it was too small a dose, I don't think we would be seeing those drops into the blues, under 200. A dose that was too small would keep you in higher numbers, the yellows, pinks, reds and blacks.
Lantus dosing is not based on the pre-shot number. Not at all. What the pre-shot number tells you is how low the number is and if it is ok to shoot the full dose, shoot a partial dose, wait to feed and retest in 30 minutes (stalling) and then give the full dose, or skip the shot entirely.
The number you base the dose on is the nadir, the low point in the middle of the cycle when insulin is given.
Since there was no insulin given this morning, we can not base a dose on the low point from today. What the curve today told us is that the insulin is lasting about 20 hours for Midnight.
What the pre-shot number told us this morning is that Midnight dropped low enough sometime last night to still be low this morning.
You said to decrease her dose down to 0.75 units so I don't have to skip any shots. But that makes it sound like you want me to give her less insulin to make her blood sugar to be above 200.
I want you to give less insulin, to smooth out the curve. To stop those constant high bounces and even out the pattern. To stop the inferred overnight low drops that are causing the bouncing. To give her body time to adjust to some lower overall numbers. Yes, many of the numbers will be over the 200. But they already are most of the time when you are testing.
Open up your spreadsheet. Put your hand over the middle columns so you are blocking out all the mid-cycle am numbers and can only see the pre-shot numbers. What do you see? I see pinks, dropping to yellows and then blues; pinks, dropping to yellows and then blues; pinks, dropping to yellows and then blues over and over again. Can you see those patterns I am talking about? (If you can't you are normal. It can take months to get to the point where you can see the patterns.)
Or are you saying she is doing well and therefore needs a smaller dose of insulin?
Yes, I do think her pancreas is trying to heal. I also think she is dipping low overnight, almost every night. Many cats do this, go low overnight. Without a few pm tests, it's impossible to teel what is happening overnight.
I am getting even more confused!!! Help!!
Normal state of affairs here in lantus land.
Let me see if Sienne and Gabby can come over to comment. She is so much better at explaining than I seem to be.
