Companion Cat Hyperthyroidism Radioiodine Treatment

Radioiodine treatment is the gold-standard cure for feline hyperthyroidism, offering permanent resolution without lifelong medication.

Key Facts

Radioiodine (I-131) destroys overactive thyroid tissue without damaging other organs
Treatment requires hospitalisation for 1-3 weeks due to radiation safety requirements
90-95% of treated cats return to normal thyroid function without further treatment
Cats with underlying kidney disease require careful monitoring after treatment
Cost and hospitalisation requirements mean radioiodine is not accessible to all owners

Welfare Considerations

Radioiodine offers permanent cure for hyperthyroidism - eliminating the welfare cost of daily medication administration and providing stable thyroid function long-term. The hospitalisation period causes temporary stress but results in a cured animal that never needs medication again. Access barriers including cost and limited specialist centres mean many cats receive suboptimal lifelong medication instead of a curative treatment.
