Hyperthyroidism

Hyperthyroidism

Species: Cat

Breeds Affected: All breeds can develop hyperthyroidism, most commonly in older cats

Feline hyperthyroidism is a hormonal disorder caused by overproduction of thyroid hormones (T3 and T4) by the thyroid gland, usually due to an adenoma. The excess hormone accelerates metabolism and affects multiple organ systems.

• Affected cats typically have a voracious appetite yet lose weight rapidly; they may also exhibit hyperactivity
• increased thirst and urination
• and a poor coat.

Treatment options include anti-thyroid medications, radioactive iodine therapy, surgical thyroidectomy, or an iodine-restricted diet.

Methimazole (Tapazole®) is the most commonly used drug. In many cases, radioactive iodine (I-131) or surgery can cure the disease.
