Radioactive iodine therapy offers a curative, single-treatment option for feline hyperthyroidism with minimal side effects and excellent long-term outcomes.
Hyperthyroidism causes chronic distress in affected cats through weight loss, increased anxiety, hypertension, and cardiac strain. While daily medication is effective, owner compliance can be challenging and some cats resist pilling. Radioactive iodine offers a curative alternative that eliminates the need for ongoing medication in most cases. The temporary isolation required post-treatment is a welfare consideration, but the long-term benefit of cure favours this approach for many cats.
