I-131 Radioiodine Treatment for Cats Near Austin, Texas

Changes in behavior, like increased energy, appetite, or restlessness, can sometimes signal something deeper going on.

Hyperthyroidism is one of the most common hormonal disorders in older cats. If your veterinarian has diagnosed your cat with this condition, they may recommend I-131 radioiodine therapy, which is widely considered the most effective treatment available.

For cat owners in Austin and Central Texas, advanced I-131 treatment is available nearby at Sage Veterinary Imaging in Round Rock. This specialized therapy targets the abnormal thyroid tissue causing the disease while allowing most cats to return to a normal, healthy life after treatment.

What Is Feline Hyperthyroidism?

Hyperthyroidism occurs when the thyroid gland produces too much thyroid hormone, which speeds up the body’s metabolism. The condition typically affects middle-aged and senior cats.

Common symptoms include:

• Weight loss despite a strong appetite

• Increased thirst or urination

• Vomiting or diarrhea

• Hyperactivity or restlessness

• Poor coat quality

• Increased heart rate

Without treatment, hyperthyroidism can eventually lead to heart disease, high blood pressure, and other serious health problems.

What Is I-131 Radioiodine Therapy?

I-131 treatment uses a small dose of radioactive iodine to destroy the abnormal thyroid tissue responsible for producing excess hormone.

Because thyroid cells naturally absorb iodine, the treatment specifically targets diseased thyroid tissue while leaving most other tissues unaffected.

This therapy has several important advantages:

• It treats the underlying cause of hyperthyroidism

• No daily medication is required after successful treatment

• No surgical removal of the thyroid gland is necessary

• Most cats return to normal thyroid function after treatment

For many cats, a single injection of I-131 permanently cures hyperthyroidism.

Why Veterinarians Recommend I-131

Veterinarians often recommend radioiodine therapy because it is both highly effective and minimally invasive.

Other treatment options for hyperthyroidism include daily medication or surgery. While these can help control the disease, they may require long-term management.

I-131 therapy is different because it directly eliminates the abnormal thyroid cells, often providing a long-term or permanent solution.

Most cats tolerate the treatment very well and return to their normal routines after completing the therapy and monitoring period.

What Happens During I-131 Treatment

Subtle changes in how your cat looks or behaves can be early signs of an underlying condition.

Cats receiving I-131 therapy stay at a licensed treatment facility for a short monitoring period after receiving the radioactive iodine injection.

The process typically includes:

Pre-treatment evaluation

Before treatment, veterinarians review your cat’s medical history and may perform blood tests or imaging to confirm the diagnosis and ensure your cat is a good candidate for therapy.

Radioiodine injection

Your cat receives a small injection of radioactive iodine, which is absorbed by the thyroid gland.

Monitoring period

Because the treatment involves radioactive material, cats remain at the facility for a short stay while radiation levels safely decrease.

Return home

Once radiation levels are safe, your cat can return home. Most cats resume normal behavior quickly and experience significant improvement as thyroid hormone levels return to normal.
