Radioactive Iodine Therapy For Hyperthyroid Cats
What is Hyperthyroidism?
Hyperthyroidism is an excessive hormone production caused by overactive thyroid glands or other tissue elsewhere in the body. It is a common disease that primarily affects middle aged to senior cats. Typical signs of hyperthyroidism are weight loss, ravenous appetite, increased thirst, increased urination, vomiting, diarrhea and matted or greasy coat. Thyroid hormones affect all the organs of the body, so when hyperthyroidism is left untreated it can cause heart disease, hypertension, kidney disease and more.
Why should I choose Radioactive Iodine Therapy to treat my cat?
- It is non-invasive. It is a simple injection under the skin that targets the abnormal hyperthyroid tissue and destroys it.
- Side effects are uncommon. Side effects are very minimal if any and will likely resolve before your pet leaves our care.
- Treatment is price effective over the long term. While it can be an investment upfront, compared to surgery or lifelong twice daily medication, and recheck bloodwork it is the least expensive option.
- IT’S CURATIVE in 90-95% of hyperthyroid cases! For the few cats where hyperthyroidism persists, the treatment can be repeated. Compared to other treatment options, Radioactive Iodine Therapy is proven to give your feline the longest lifespan.
Hyperthyroidism and Kidney Disease
Hyperthyroidism increases cardiac output dramatically. This, in turn, increases blood flow to the kidneys which can mask underlying renal disease. Once hyperthyroidism is treated these effects subside and may make kidney disease seem worsened or more apparent. It is important to remember that the treatment did not cause kidney disease.
Other treatment options:
- Medication — A drug used to reduce the production and release of the thyroid hormone for short or long term control. Most often a twice daily oral dosage is given for the cat’s lifetime, patients need to follow up with their family veterinarian regularly for rechecks and routine blood tests.
- Surgery — A surgical procedure called a thyroidectomy removes the thyroid gland. As with any surgery that involves general anesthesia, there are risks. Older cats or cats with heart or kidney disease are at increased risk for possible complications. Successful surgery can be curative.
As with any treatment plan, it is important to address any concerns with your family veterinarian. They will be able to help you weigh the risks vs. the benefits for your individual pet.
