Isn’t it better to be conservative with treatment rather than testing and giving insulin so often to achieve normal or near-normal blood glucose levels?
Definitely not. What we know is that high blood glucose levels intoxicate the pancreas, and suppress the normal functioning of the liver. Until blood glucose in the cat begins to be normal or nearly so for much of the time, these organs will not begin to work effectively together. Once they begin to work properly together again, permanent normalcy is possible, even probable.. If a cat is maintained at hyperglycemic blood glucose levels, it cannot be said to be well-regulated at all, and will not resume normal pancreatic and liver function and cease dependency on insulin shots.
