Understanding
hyperthyroidism in cats
What is hyperthyroidism?
Hyperthyroidism occurs when the thyroid gland,
located in the neck, produces a hormone called thyroxine
(T4) in excessive amounts. Thyroxine is involved in
many physiological processes in the
body particularly related to metabolism.
Hyperthyroidism is very common
in older cats. The cause is currently
unknown and in most cases is related to
a benign swelling, although in rare cases
can be linked to a tumour of the thyroid.
What are the symptoms?
• Weight loss
• Ravenous appetite (but in some cases
it can be normal or reduced)
• Reduced coat quality
• Increased thirst and urination
• Vomiting or diarrhoea (can be
intermittent)
• Hyperactive, unsettled, nervous,
vocal or irritable
How do you test for it?
Usually, a simple blood test to check
the levels of thyroxine in the blood is
sufficient for diagnosis. Although some
cases require additional tests.
How is it treated?
There are four main treatment options,
each with their own pros and cons and
differing costs:
1. Lifelong medication: Available as oral tablets or
a gel applied to the ear daily. This aims to reduce the
thyroxine levels down to normal range. Regular blood
tests are needed initially, and throughout life to monitor
levels.
2. Radioactive Iodine: Cats are required to stay at a
treatment centre for between 7-10 days for treatment
with a radioactive chemical which attacks the overactive
thyroid only. The aim of this method is to cure
hyperthyroidism and prevent the need
for medication in future. In rare cases, a
second round of treatment is required.
3. Prescription diet: Lifelong diet. No
additional food – treats or hunting – or
the diet will not work adequately.
4. Thyroidectomy: Surgical removal of
the affected thyroid gland. Less common
given the possible risks or damage to the
parathyroid gland.
