Hyperthyroidism is a pet health issue that occurs in cats over the age of eight. Hyperthyroidism is caused by an overactive thyroid gland. The excessive thyroid hormone overstimulates the body causing the cat to become overactive and have an increased appetite. It is important to be diligent about cat health care, especially in aging cats. Catching diseases early can add years onto your cat’s life.

The number one symptom of feline hyperthyroidism is weight loss. This symptom is similar to those seen in other feline diseases. Other cat weight loss causes include diabetes and kidney failure. Hyperthyroidism causes the cat to lose wight even though she has a ravenous appetite. Other symptoms of feline hyperthyroidism can include increased thirst, vomiting and diarrhea. Cats with hyperthyroidism will also have an increased heart rate. This increase in heart rate can cause damage to the heart and if left untreated, can lead to heart failure and eventually death.

Once hyperthyroidism is suspected, your veterinarian will run blood tests to evaluate the levels of thyroid hormones in the blood. Blood tests will also be run to rule out other diseases with similar symptoms. The blood work will also let the veterinarian know how well the other organs of the body are functioning. Once a diagnosis of hyperthyroidism has been made, the cat can then begin treatment.

If your cat is showing symptoms like those mentioned above– a visit to your veterinarian may be necessary. For some injuries and sicknesses, cat insurance may be a good way to ease the blow of costly veterinarian bills.
