What is hyperthyroidism?
The thyroid gland, located in your cat’s neck, uses dietary iodine to make thyroid hormones (thyroxine) that help regulate important body functions, including:

  • Metabolism
  • Body temperature
  • Blood pressure
  • Heart rate
  • Gastrointestinal function

When a cat has hyperthyroidism, its thyroid gland is enlarged and it produces excessive amounts of thyroid hormone.

Hyperthyroidism is most often diagnosed in cats older than 10 years. Untreated hyperthyroidism can have serious — even fatal — effects on organs such as the heart and kidneys.

What are the signs of hyperthyroidism?

  • Weight loss
  • Increased appetite
  • Diarrhea
  • Vomiting
  • Increased thirst
  • Poor skin and coat condition
  • Hyperactivity

Because some of these same symptoms can appear as a result of other diseases, such as diabetes or kidney failure, your cat will need tests such as a blood profile and urinalysis to determine the actual problem.

Did you know? An over-active thyroid is more common in cats than in dogs, and an under-active thyroid is more common in dogs than in cats.

How is hyperthyroidism treated?
There are four types of treatment available today:
1. Daily nutrition: limiting intake of dietary iodine reduces thyroid hormone production. One such food available to cat owners is Hill’s Prescription Diet y/d.
2. Daily medication: anti-thyroid drugs inhibit the production of thyroid hormones. Such drugs must be administered with caution, so that the person giving the medication does not accidentally absorb the drug.
3. Radioactive iodine therapy: radiation to treat abnormal thyroid tissue. This procedure is performed by a veterinary specialist, available through a referral by your regular vet. Treatment is considered highly effective, though it can be expensive if the pet is not covered by pet health insurance.
4. Surgery: removal of diseased thyroid tissue. Surgery is often successful, though some cats may afterwards require thyroxine replacement therapy either short-term or long-term.

Can I purchase Hill’s Prescription y/d at the store?
Y/d is available only through veterinarians. Because it is designed to act on thyroid hormone production, the food is not appropriate for all pets in a household; for this reason, it is not sold as an over-the-counter product.

Why does the veterinarian recommend y/d?
In tests, y/d (when fed alone, without treats or other foods) improved thyroid health in 3 weeks. Also, when properly fed, the food is designed to eliminate the need for anti-thyroid drugs. Y/d also provides the daily nutrition your cat needs to stay healthy.
And remember what we said about hyperthyroidism affecting kidney and heart health? Y/d addresses those issues, too. Y/d contains carnitine and taurine for the heart and reduced sodium levels for kidney health.
