I-131 Treatment
FELINE HYPERTHYROIDISM & I-131 TREATMENT IN HOUSTON
What is Hyperthyroidism in Cats?
Hyperthyroidism is the most common endocrine disorder in senior cats, resulting from an overactive thyroid gland that produces too much thyroid hormone. These hormones can lead to several health issues, including heart disease, high blood pressure, weight loss, and gastrointestinal symptoms like vomiting and diarrhea. Early diagnosis and treatment are crucial for managing hyperthyroidism.
At Gulf Coast Veterinary Specialists, we specialize in I-131 radioactive iodine therapy, also known as I-131 treatment, which is a fast and effective option for cats suffering from hyperthyroidism. We are among the few hospitals that can offer I-131 therapy in Houston, which boasts a cure rate of over 95%, making it the preferred choice for most patients.
Why Choose I-131 Treatment for Hyperthyroidism?
Radioactive iodine therapy (I-131) is highly recommended because it noninvasively targets overactive thyroid tissue, no matter where it is in the body. Unlike surgery or medications like Methimazole, iodine therapy offers a permanent cure with rare side effects and typically requires only one dose to return your pet’s thyroid function to normal.
Benefits of I-131 Treatment:
- Non-invasive
- Permanent solution in over 95% of cases
- Minimal side effects
- Only requires one dose in most cases
How Does I-131 Treatment Work?
By administering a small subcutaneous injection of radioactive iodine that targets and destroys hyperactive thyroid cells while leaving healthy tissues unharmed. At GCVS, our experts use nuclear scintigraphy to tailor the exact dose needed for your cat’s unique case of hyperthyroidism.
Gamma Camera & Thyroid Scans
Before administering iodine therapy, we perform a thyroid scan to confirm the diagnosis and assess the severity of the condition. This scan helps differentiate between benign and malignant thyroid masses, ensuring precise and individualized treatment. GCVS adheres to the highest standards of care, backed by over 25 years of experience successfully treating hyperthyroidism.
FREQUENTLY ASKED QUESTIONS
Hyperthyroidism is typically diagnosed with a blood test measuring the elevation of the thyroid hormone (Total T4 and/or Free T4). However, a thyroid scan is the only way to 100% accurately confirm or deny feline hyperthyroidism. It is the “gold standard” method of testing and is often required to confirm the diagnosis in difficult cases where hormone levels appear normal. At GCVS, we use nuclear thyroid scans to accurately diagnose before proceeding with treatment.
The I-131 treatment is administered via a subcutaneous injection. After treatment, your pet is monitored 24/7 at our hospital for 3-7 days (depending on dose) until radiation levels drop to a level considered safe by the state. Owners must also follow post-treatment guidelines at home, which include minimizing contact with your cat for two weeks.
Most cats undergoing I-131 treatment experience a significant improvement almost immediately, but definitely within a few weeks, with a success rate of 95% with one injection. The recovery process is typically smooth, with minimal side effects, allowing your cat to return to a healthy, balanced state.
