Radioactive iodine (I-131) therapy is the gold standard treatment for feline hyperthyroidism and is very effective with few side-effects.

Dr Martine Perkins has incorporated a state of the art, Gammasonics treatment room into the Killara Hosptial to correctly manage the treatment of hyperthyroidism and hyperparathyroidism in cats.

What is Hyperthyroidism?

Hyperthyroidism is a common disease and mostly afflicts cats middle-aged and older. Also called thyrotoxicosis, hyperthyroidism is caused by an increase in production of thyroid hormones (known as T3 and T4) from an enlarged thyroid gland in a cat’s neck.

What is the Treatment?

This treatment is administered with a single oral capsule. It’s the same treatment used for humans suffering hyperthyroidism, eliminating the need for lifelong tablets. 

The Village Vet is one of only a few practises in Sydney that has these facilities on-site and fully qualified staff to administer this specialist treatment. 

Signs of Hyperthyroidism

The most common clinical signs of hyperthyroidism are weight loss, increased appetite, increased thirst and urination. Hyperthyroidism may also cause vomiting, diarrhea, and hyperactivity. The coat of affected cats may appear unkempt, matted or greasy

If your cat is showing any of these signs, bring them in to us for a through check over and we will ensure a correct diagnosis prior to any recommendations.
