Can Hyperthyroidism CAUSE High Liver Enzymes ...
in cats with no liver damage?
This is apparently the question. Talked to my vet today, and he will agree that Buddha should have Tapazole before the ratiation treatment if I can find an article that says that hyperthyroidism can cause high liver enzyme readings in blood tests when there is no real liver damage present. He already knows that hyperthyroidism can cause liver damage and that this is what the elevated enzymes in the last test might mean. He agrees that hyperthyroidism can mask kidney disease by indicating normal kidney function in blood test, when there is actually kidney disease present that shows up after thyroid hormone levels are brought back to normal. Is this clear? I am searching for an article that says that hyperthyroidism can cause elevated liver enzymes in the absence of real liver damage--so that when Tapazol is used to bring thyroid hormone levels back to normal, we find that liver function is actually normal. Any help will be greatly appreciated. We see him this afternoon. |

Here's another link that has a sample blood profile of a hyperthyroid

wrote in message ... This article says that it does: http://www.veterinarypartner.com/Con...16&SourceID=42 Megan Thank you. By the time I got to his office my vet had found an article that says so. Now all Buddha has to do is have a urine test and she can go on Tapazole. (We tried today but her bladder was empty.) I take her back in the morning to have another go at collecting urine. If she is shown to have normal kidney function after she is on Tapazole for a while (we have not discussed how long) we can go ahead with the radioactive iodine treatment. I appreciate everyone's help with this. Although in a perfect world all vets would know everything there is to know, I am still happy with mine because he at least listens. Now that he knows, he can try other cats who show elevated liver enzymes on Tapazole to make certain their hyperthyroid is not masking kidney disease. |

I am so glad she is not as old as many hyperthyroid cats are when diagnosed, because she is stronger and there are apt to be less complications with both the medication and the radiation. I just hope we find that her renal and liver function are normal after the round of Tapazole. I mentioned that I found it odd that she shows none of the really classic "outer" symptoms of hyperthyroid, such as an unkempt-looking coat and a low weight. The doctor pointed out that in addition to her elevated heart rate (300 bpm) and thryroid hormone level (10+) she LOOKS like a hyperthyroid cat. I asked what that meant and he said "she looks hyper-alert." This is true, and part of what has always made her so funny to watch. When she plays her reflexes are super fast, and she never has that "heavy lidded" look most cats do. This is the cat who, when I hold her a minute too long, stares at me wide-eyed and stiff-arms me, curls her lip back and bitches at me. No growl, no hiss, just "Meh meh meh, mmmrowwllll!!" Another part of the syndrome is irritability. Buddha gets comfortable on my lap on the couch and if I move she rips off a mean meowwwll and HISSES at me as she gets down. Very reactive. Thanks for your help. Let's hope we can get a urine sample tommorow and get her started on Tapazole. |
