About Feline Hyperthyroidism

Feline hyperthyroidism is an endocrine disorder caused by a "benign goiter" of one or both thyroid glands that causes an elevation of thyroid hormone levels. The disorder commonly affects older cats.

Radioactive Iodine Therapy Treatment

Radioactive iodine therapy is an extremely effective treatment for treating feline hyperthyroidism. Candidates for the radioactive iodine therapy should be relatively healthy cats that have been off their feline hyperthyroid medications for at least two weeks prior to treatment. The treatment protocol is as follows:Feline Hyperthyroidism Exam

  • Upon admission, patients are provided with a comprehensive health evaluation and a thyroid scan to ascertain the extent of the problem and to develop a therapeutic approach.
  • A low dosage of radioactive iodine is administered to the patient through a single subcutaneous injection.
  • The agent is accumulated and concentrated in the abnormal parts of the thyroid glands.The iodine destroys the diseased tissue, while healthy thyroid tissues are not affected.
  • Once the agent is injected, the patient must be kept in isolation for three or four days while the radioactive agent is cleared from the body.
