My 10 yr old cat was diagnosed with hyperactive thyroid based solely on a blood test, no xrays could be done , but I don't think his symptoms match. He lost his appetite and a bit of weight, was constipated to prompt me taking him in. Anything I've read dictates an increased appetite with weight loss. Now he's on meds twice a day and is becoming lethargic, he doesn't seem himself at all. Could there be something else wrong or is an elevated T4 the only test result to diagnose this thyroid problem? What is the success rate for Iodine therapy? Is there a chance he may not accept it?
Hello, I just had to answer your post. I had two brothers(same litter) that were about 10 yrs old that had hyperthyroid, too. BOTH of them. They were both diagnosed by the blood test that measured T4 levels-x rays do not diagnose this. This test is very very accurate and measures the hormones that are released from the thyroid gland Type in T4 levels in the yahoo or google search engine, and you can see for yourself how accurate this test is. There is also a test that checks T3 levels as well, this is also a thyroid hormone.
I was also considering the radioactive iodine treatments for my cats, too. Yes, it's close to 100% effective, but the cost is up there-@$1000+(at least in Va). What stopped me from going ahead with it was one of them had cancer-found on an x-ray, and the other brother had poor kidney function. I would have definitely gotten them the treatment, if there were no other health problems. Instead, I chose the drug route, which was Tapazole. So, there is a drug option out there for you. I think the iodine option would be better if you can swing it, though. I wish I had that option.
