This morning I took I took Holly to the Vet. She tested at 323. The Vet told me to give her 4/units of insulin and recheck her GL this afternoon as we might be able to skip the PM shot. She had a good night. She ate her food and now i'm going to give her 4/units once i get some food in her.
Can anyone help me find a Vet who specilizes in diabetes in the Greenville NC area?
So, here is what I think is happening.
You give her insulin, she goes really low (blood sugar less than, say, 90), and, to keep herself alive, her liver dumps a bunch of sugar into her system, so she has something to use for energy which will keep her breathing and living. Then, her sugars read high, and you dose insulin on the high number...and she goes low, and then her liver reacts, and dumps sugars into her system...and around and around she goes.
How insulin works is that it's the transporter for the sugar to get into the cell, so the cell can have enough energy to do it's job. I imagine it's like sugar has a hand, but can't open the front door of the cell. The insulin has a hand and the ability to open the door...so it holds the sugar's hand and walks it into the cell. When you have high numbers, it's because the sugars can't open the cell door, and when you give insulin, it goes to work walking the sugar into the cell. If there's too much insulin, it's just sitting there, waiting for a sugar to go by, and it grabs it and throws it into the cell...leaving nothing for the rest of the body to work with and use.
The liver, wonderful organ that it is, sees that there's not enough sugar for the insulin to work appropriately with, and dumps out some stored sugars, just to give the insulin something to do. So, it sends out more sugar, and the insulin gets overwhelmed, and gets worn out throwing sugar into the cells, and then gets used up...but there's still sugar in the blood, waiting for the insulin to come along and hold it's hand and open the cell for it to go in.
The key is to maintain a decent level of sugar in the blood, without the liver freaking out and throwing more sugar into the system, and having enough insulin there so it can open the cell and escort the sugar into it.
If you have a high number, a reasonable thought would be to put in more insulin. But do you see how, if there's too much insulin, you'd end up with the liver freaking out and dumping far too much sugar back into the system, and making it look like you'd need more insulin? So then you give more insulin, and the liver says "woah, I didn't give enough last time...here's a bit more..." and then there's another high number. And the cycle continues on...high sugars, insulin, low sugars, liver freak, high sugars, and so on...
The ONLY way to find the right dose for your particular kitty is to start low. Start at the bottom and work your way up. You've got to break the cycle somehow, and if that means your baby stays a little high for a while, that's acceptable and doable. Start down at 1 unit, test every two hours for a while, and find the low spot (the nadir). Post the low number of the day, and the dosing team will be able to help you decide if you should go higher or lower.
It's so dependent on the kitty's own body that no one set rate is an across the board answer. I completely understand the whole "I wanna fix this now, and help my baby" feeling. Each and everyone of us has felt that. But what we've come to understand is that each cat is different, and each day is different for each cat...and that it does indeed take some experimenting to find the right dose for that cat...and sometimes, the experimenting makes us really, really nervous and unsure of what we're doing.
These boards are superb in getting a lot of folks' opinions and advice and experience...and helps us sort ourselves and our cats' sugars out.
Please listen to the collective years of widsom here...they can help you get sorted out, and Holly will be better for it. Hang tight, all right? Start low, go slow...it's really the best way.
Best-
