Q. My cats shows symptoms of hyperthyroidism but its thyroid test showed nothing wrong. The blood test only shows high liver enzyme. What shoukd i do?

A. If the blood test shows high liver enzymes I would recommend having a bile acid test done to check liver function. High liver enzymes, depending on how high, does not mean that the liver has loss of function, which is why a bile acid test is then done to gain more information here. For a cat this young, hyperthyroidism is very unlikely anyway.
I also recommend for any patient of mine with high liver enzymes to go on liver protectant medication (SAM-e or Denamarin) for 30 days to help protect the liver from an acute insult. Most of the time this is the extent of the medication needed if the bile acid comes back normal.
