Re: 10/17 Toby,s AMS=439+4=375
There are reasons to know what's going on to cause the high dose condition - that's why we've suggested having him tested. That's too bad that the vet didn't just do it - we wouldn't suggest it if it weren't important. It really helps us to know what direction to advise you.
If a cat has iaa, we encourage aggressive dosing because you want to break through the resistance, but you might use more R and less L because when the iaa does break (take a look at what's going on with Cobb this week), the insulin that was bound to the antibodies is released, causing an increase in the amount of insulin now available in the body. With iaa, you really want to concentrate on getting a cat into normal (green) numbers as much as possible.
If a cat has acromegaly, that is caused by a benign tumor on the pituitary gland. The tumor can ramp up and down production of the growth hormone that blocks the insulin from being able to get into the cells. A cat with acromegaly can be treated by Steriotactic Radiation - some then go off of insulin, but if not, the dosage will be significantly reduced. If you choose not to treat the acro with SRT, you will just give more and more insulin. In that situation, you're not going to be aggressive about putting a cat into green numbers necessarily. You might be content with trying to just keep Toby in blue numbers.
The strategies are different. The saying here is that if a cat has acromegaly, it "trumps" iaa, meaning that if a cat has acro, and you're not getting him treated, it is going to be safer to act as though the cat has acro only and let the cat run a little higher.
Without knowing, we're just stabbing in the dark and telling you to give more insulin as the numbers suggest. It's a bit like saying that an infection requires an antibiotic, so just give one without knowing what the bacteria is and targeting the AB towards that particular bacteria. I'd call it a half-way job and not the best strategy for Toby. To me, it really hinders those of us who are trying to help you.
