Thyroid Profile

The thyroid gland produces thyroid hormone. Thyroid hormone is responsible for the body's rate of metabolism, including hair growth and immune defenses among other important functions. The over- or under-production of thyroid hormone may be evident in many physical examination findings such as hair loss, significant weight and appetite changes, and changes in behavior.

Different forms of thyroid disorders exist, but the most common forms vary along with species. Cats are more likely to have hyperthyroidism, or an overactive thryoid gland which is producing too much thyroid hormone. Dogs are more likely to have hypothyroidism, or an underactive thyroid gland which is producing too little thyroid hormone.

A thyroid profile will allow evaluation of your pet's thyroid function and allow monitoring of medication if indicated. There are several thyroid hormone levels and stimulation tests which may be performed. Your veterinarian will order the type of testing needed for your individual pet's condition.

Medication is available to slow thyroid hormone overproduction or to supplement synthetic thyroid hormone as appropriate for your pet's condition. The appropriate dosing of such medications will be periodically monitored and adjusted based on findings on your pet's thyroid profile.
