[Extract] Feline hyperthyroidism is a multisystemic disease resulting from excessive secretion of thyroid hormones, L-thyroxine (T4) and/or L-triiodothyronine (T3). This disorder is now the most common endocrine disease of middle-aged to older domestic cats (average age at diagnosis = 12-14 years, range 4-22) diagnosed at veterinary clinics in New Zealand and many other countries. The most common clinical signs are weight loss, polyphagia and hyperexcitability. Functional thyroid adenoma (multinodular adenomatous hyperplasia), involves either one lobe in about 25% or both thyroid lobes in about 75% of cases and accounts for at least 97% of diagnosed cats with hyperthyroidism. A number of suspected cases were reported in the veterinary literature from 1955 onwards but the first confirmed cases were in 1979. Despite progress in improving the diagnosis and treatment of feline hyperthyroidism, it has been observed that over time there has been an increase in the incidence of this disease.
