Gooday. Dominic Barfield here, and this is the RVC Clinical Podcast. Thank you for listening and thank you for subscribing on your smartphone or generic fruit-based device.

We're really grateful for you to taking the time and down to download and listen to this obviously clinical podcast. And we don't ask for anything in return.

Well, maybe that's a, maybe that's a lie. If you could actually go to the Apple Podcast or iTunes store and leave us a review.

A five-star review would be great. I'm sure there are other star reviews possible, but five-stars would really be beneficial to us to work on metrics that neither Brian or myself understand, but one day we will with the fullness of time.

But basically that allows us to work on some metrics to allow this information

to at least be more accessible to the people that want to listen to it. So that would be great

if you could just spend a couple of minutes of your day to go to the Apple podcast store and leave us

review. So today we're going to talk to Professor Hattie Sime. Hello,

Hello, Hattie. How are you? I'm fine. Thank you, Don. And so we thought about the

talk about the idea about the interplay between renal disease and hypothyroidism. So thank you for

joining us today, Hattie. So it's a place where would be a good place to start between hypothyroidism and renal disease?

Is there a subset of patients that we know that have chronic renal failure that have hypothyroidism

or a subset of patients that we know have hypothyroidism might have undark nose renal disease?

Yeah, there's huge interplay between these two conditions because obviously they're both conditions of the older cat and I would say that a large number of the consult calls that we get from referring vets and questions that are addressed to us

are about this interplay between the two. And it works in both directions. So we'll have questions

about cats that have developed azatemia or following treatment for hypothyroidism. But we'll also, and something that gets talked about perhaps less,

is the situation where a cat clinically perhaps is thought to be hyperthyroid.

It's showing signs suggested of that.

The patient's got pre-existing azatemia are known to have renal disease,

and yet hypothyroidism isn't diagnosed, or at least the total T4 concentrations are not

elevated the first time the test is run, and then the question arises, okay, is this cat with a quote

on quote normal T4? Is this cat actually hypothyroid?
