Hi everyone, Milo started Prozinc in late December 2017 at 2 units twice a day. I bought the Alphatrak meter and started home testing. The first glucose curve on 1/13/18 showed 611, 397, 623, 638, 584, and 530. He was very stressed and we were very lousy at pricking his ears because it was our first time. Our vet said to up insulin to 3 units twice a day and we did the curve again on 1/27/18 and we got 614, 458, 468, 385, 580, 582. Vet thought this was a good curve and he's not insulin resistant. At his one month recheck at the vet, his fructosamine was 393. Not horrible. Vet suggests we move up to 4 units of insulin twice a day. We did a curve on 2/18 and we got 646, 571, 474, 501, 533, 554. Vet is now concerned Milo might be insulin resistant. She suggests we test for Acromegaly and Cushings. We have not increase his insulin - he is still at 4 units twice a day. Anyone have any thoughts on what is going on? Why did we not see an improvement when we up the insulin from 3 to 4 units? Milo also has irritable bowl disease, stage two kidney disease and on hyperthyroid medicine. So lots going on with my old man. He's about to turn 18 years old! He is on prescription hills k/d wet and my vet recognizes this is not the best option for a diabetic but wants to focus on his CKD. I've read that many folks say forget the prescription diet and I understand, but I am also super nervous to not follow my vet's advice. Any tips or thoughts would be wonderful!
