Thyroid disorders in the geriatric patient.

Thyroid disorders are common in older pets. They often present a diagnostic challenge, and reaching a definitive diagnosis can be difficult or impossible in some cases. It is important for the veterinary practitioner to be familiar with the historical, physical examination, and clinicopathologic data findings in each of these diseases and to become comfortable with the treatment, monitoring, and prognosis associated with thyroid diseases in geriatric pets.
