at Tier 1 Veterinary Medical Center

Effective Solutions for Your Cat's Thyroid Health

At Tier 1 Veterinary Medical Center, we specialize in the treatment of feline hyperthyroidism (FHT), a common condition in older cats, using Iodine-131 therapy. This article will explain what FHT is, how to recognize its symptoms, the treatment options available, particularly Iodine-131, and what to expect from this treatment.

What is Feline Hyperthyroidism (FHT)?

Feline hyperthyroidism is a disorder resulting from the excessive production of thyroid hormone by the thyroid glands. It is most commonly seen in middle-aged to older cats. The thyroid hormone affects virtually all organs, with its excess leading to serious health issues.

Signs Your Cat May Have Hyperthyroidism

The symptoms of hyperthyroidism in cats can vary widely, but common signs include:

  • Increased appetite
  • Weight loss despite an increased food intake
  • Increased activity and restlessness
  • Aggressive or irritable behavior
  • A faster heart rate
  • Vomiting or diarrhea
  • A poor coat condition

Treatment Options for FHT

The treatment for feline hyperthyroidism can include medication, surgical removal of the thyroid glands, dietary changes, or radioactive iodine therapy (Iodine-131). Among these, Iodine-131 is considered one of the most effective and curative options.

What is Iodine-131 Therapy?

Iodine-131 therapy involves a single injection of radioactive iodine, which is absorbed into the cat’s bloodstream and taken up by the thyroid gland. The radioactive iodine destroys the overactive thyroid cells without harming other tissues or requiring surgery.

Benefits of Iodine-131 Therapy

  • Non-invasive and does not require anesthesia
  • Highly effective, typically requiring just one treatment
  • Minimal risk of complications
  • No daily medication required after treatment

What to Expect During Iodine-131 Therapy

Here’s what to expect when your cat undergoes Iodine-131 treatment at Tier 1 Veterinary Medical Center:

  • Initial Evaluation: Your cat will undergo a thorough evaluation to confirm the diagnosis of hyperthyroidism and to assess their overall health.
  • Treatment: The Iodine-131 injection is administered. This is a quick and simple procedure.
  • Post-Treatment Care: Cats typically stay at our facility for a few days to allow the majority of the radioactivity to decrease. Our trained veterinary staff monitors their recovery.
  • Follow-Up: After returning home, some precautions may be necessary for a short period to minimize radiation exposure to humans. A follow-up visit will be scheduled to assess your cat's response to the treatment.
