Definition Header

Feline Hyperthyroidism is defined as a persistent abnormal elevation of thyroid hormone which results in a fatal disease. Abnormal levels of thyroid hormone are produced by thyroid tissue that has lost its ability to be controlled by normal level sensing mechanism that turns on and off thyroid production. This malfunctioning tissue represents only a portion of the total thyroid gland; the remaining tissue is suppressed and will not function until the abnormal tissue is eliminated. This condition is very prevalent in cats and very rare in dogs.

 

SIGNS OF THE DISEASE INCLUDE:
Weight loss (may be gradual or rapid)
Increased appetite
Vomiting
Diarrhea
Hyperactivity
Aggression
Age range - 6 years and older cats
Self mutilation, hair pulling
Cardiac Arrhythmia - resulting in sudden death - usually due to abnormal heartbeat
