Hyperthyroidism in Cats: Past and Upcoming Topics

As you know, if you have been following this blog, I've spent much of the last few months writing about issue of hyperthyroidism, the most common endocrine disorder of the cat.

Unfortunately, I got sidetracked and have not yet finished discussing all of the treatment options that we have for management of this common problem. However, I do plan to finish up this series of topics over the upcoming weeks.

But before I move on to the topics of treatment of this common feline condition, I thought I'd post links to the topics I've covered thus far:
  1. Do All Hyperthyroid Cats Have a Thyroid Tumor? Is It Thyroid Cancer?
  2. Why Has Hyperthyroidism in Cats Reached Epidemic Levels?
  3. Top 10 Signs of Hyperthyroidism in Cats
  4. Top 12 Physical Exam Findings in Cats with Hyperthyroidism
  5. Hypertension (High Blood Pressure): A Common Problem in Cats
  6. Diagnosing Hyperthyroidism in Cats: Routine Testing Procedures
  7. Diagnosis of Hyperthyroidism in Cats: Serum T4 Concentrations
  8. Diagnosis of Hyperthyroidism in Cats: Serum T3 Concentrations
  9. Diagnosis of Hyperthyroidism in Cats: Serum Free T4 Concentrations
  10. Diagnosis of Hyperthyroidism in Cats: Serum Free T4 (Part 2)
  11. Diagnosis of Hyperthyroidism in Cats: Serum Free T3 Concentrations
  12. Diagnosis of Hyperthyroidism in Cats: Serum TSH Concentrations
  13. Diagnosis of Hyperthyroidism: T3 Suppression Test
  14. Diagnosis of Hyperthyroidism: TRH Stimulation Test

  18. Daily Water and Fluid Requirements and Needs for Hyperthyroid Cats

I'll be posting my next post on feline hyperthyroidism (entited, Antithyroid Drug Treatment for Hyperthyroidism: Brand Name, Generic, or Compounded Drug?) within the next couple of days; then I'll continue with treatment issues, with about a post once a week.

Dr. Peterson,
This site has been extremely helpful as I deal with my cat newly diagnosed with hyperthyroid. He's started on Methimazole, but I'd like to know more about the radioiodine treatment and your thoughts on it vs the meds. I'm considering going that way and would like to have more info at hand about the pros and cons.
I hope you'll post soon about this topic (I see you've been sidetracked :)

Sorry about my delayed posts. However, I think you should find all of the information that you are looking for on my website (

In brief, however, the main advantage of either radioiodine or surgery is that we are treating the underlying cause (ie, the thyroid tumor). Medical or nutritional management lowers the T4 but allows the thyroid tumor to continue to grow. In some cats, the tumor can transform into a malignant thyroid carcinoma.
