Medicine

What is feline hyperthyroidism?

Hyperthyroidism is a benign condition caused by overproduction of thyroid hormone by the thyroid gland. It is common in cats over 8 years of age but can affect younger cats as well. Malignant cancer of the thyroid gland can also occur but is rare in cats.

What are the signs my cat may be hyperthyroid?

Clinical signs include weight loss, increased appetite, vomiting, diarrhea, drinking and urinating more, and nervousness or hyperactivity. Elevated thyroid hormone levels can cause high heart rate, benign heart murmurs, arrhythmia and high blood pressure.

 

Safety

Is iodine radiotherapy safe for my cat?

Iodine radiotherapy is the safest method of treating hyperthyroidism in cats. There are no risks of surgery, no anesthesia, and no medication side-effects.  Unlike low-iodine diets and medication which can only manage hyperthyroidism, radioiodine therapy cures the underlying disease

Are there contraindications for radioiodine therapy?

Hyperthyroidism is most common in older cats, so it is not unusual for a hyperthyroid cat to have other health problems. A complete blood workup (blood count, serum chemistry panel), urinalysis, and a chest x-ray are performed by your veterinarian as a preliminary evaluation. We will discuss any health concerns with you and your veterinarian prior to scheduling treatment.

Is it safe for me and my family?

Yes! The NRC and the Pennsylvania DEP closely regulate the use of radioactive isotopes in veterinary patients. There is minimal radioactivity remaining in the body when your cat is discharged 72 hours after therapy. Our staff will show you how best to minimize your exposure after you bring your cat home.

 

Efficacy

How effective is iodine therapy?

Radioactive iodine is the most effective method for treating hyperthyroidism in cats. Surgical resection requires anesthesia and there is a risk of surgical complications. Medical management requires daily dosing of medication for the life of your cat. Low-iodine diets require you to strictly control your cat's diet, and are typically not feasible in multi-cat households.  With iodine therapy, one treatment is usually effective for life. If your cat's hyperthyroidism ever recurs, we will treat again at no cost!

Can treating my cat cause hypothyroidism (low thyroid levels)?

Hypothyroidism, which results from low levels of thyroid hormone, can cause signs such as lethargy, dullness, obesity, dandruff, oily skin, and matted fur. Only 1-2% of cats treated with radioiodine therapy develop hypothyroidism. In many cases the condition is transient and resolves spontaneously. If needed, cats can be easily treated with supplemental thyroid hormone given orally as a pill.

 

Logistics
