Feline Hyperthyroidism Prognosis


If your cat was recently diagnosed with feline hyperthyroidism, you may be wondering about his or her prognosis. Many pet owners are unaware of the condition and may not know what to expect.

The good news is that the prognosis for feline hyperthyroidism is not all bad. In fact, when treated early and effectively, many cats can fully recover and have normal thyroid activity restored.


What is Feline Hyperthyroidism?

Before you learn about feline hyperthyroidism’s prognosis, you’ll need to understand the nature of feline hyperthyroidism. Feline hyperthyroidism occurs when a cat’s thyroid gland creates an excess of the thyroid hormone. This affects a cat’s metabolism, and can result in weight loss, increased appetite, increased activity and restlessness, a matted, greasy or poor coat, a fast heart rate, increased water drinking, vomiting, diarrhea, difficulty breathing, and weakness. If left untreated, the condition can be fatal.

The prognosis for cats with feline hyperthyroidism varies depending on what type of treatment the cat receives. There are a few different treatment options, including radioactive iodine therapy, surgical treatment, and medication.


Effective Treatment for Feline Hyperthyroidism

The prognosis for feline hyperthyroidism is best when treated with radioactive iodine therapy. This treatment involves an injection of radioactive iodine, which is absorbed quickly into the cat’s bloodstream. The iodine will destroy abnormal thyroid tissue, leaving surrounding tissues and parathyroid glands untouched and thus not causing any additional damage. After your cat is injected with radioactive iodine, he or she will need to remain in a treatment facility for a few days to be monitored until radiation levels are acceptable. Radioactive iodine treatments can only be performed at specially licensed facilities.

Remember: the prognosis for feline hyperthyroidism is better the earlier it is caught and treated. If your cat is experiencing symptoms of feline hyperthyroidism, please contact your veterinarian immediately.
