Hyperthyroidism in Cats

Hyperthyroidism in Cats

Hyperthyroidism and hypothyroidism are similar words but don't get them confused, these conditions are very different. Today our Lexington vets share a little about the symptoms and causes of hypothyroidism in cats.

What is my cat's thyroid?

The thyroid is a gland in your cat's neck that produces a number of hormones that help to regulate many processes in your cat's body, including metabolic rate.

What is the difference between hypothyroidism & hyperthyroidism

If your cat is diagnosed with hypothyroidism it means that their thyroid is underactive, and producing fewer thyroid hormones than are required for a healthy metabolism.

On the other hand, if your cat produces too much thyroid hormone, then your kitty is suffering from hyperthyroidism.

While hyperthyroidism is a common condition often seen in older cats, hypothyroidism is relatively rare.

What causes hypothyroidism in cats?

Although sometimes caused by cancer, iodine deficiency, or congenital disease (thyroid gland abnormalities), hypothyroidism is a rare condition most often seen in cats who have undergone surgery or iodine therapy as a treatment for hyperthyroidism (overactive thyroid).

What are the symptoms of hypothyroidism in cats?

The reduced levels of thyroid hormones seen in cats with hypothyroidism leads to a slowing of the cat's metabolism which can result in one or more of the following symptoms:

  • Cold intolerance
  • Weight gain
  • Hair matting
  • Constipation
  • Neurological changes
  • Unkept appearance
  • Weakness
  • Lethargy
  • Mental dullness
  • Hair loss / Excessive shedding
  • Inactivity
  • Low body temperature

If your cat is showing any of the signs above contact your vet to book an examination for your feline friend. While the above symptoms can indicate hypothyroidism in cats, they can also be related to a number of other serious conditions which require veterinary attention.

What is the treatment for cats with hypothyroidism?

Often no treatment is necessary for cats with hypothyroidism. However, if your kitty's symptoms are severe your vet may prescribe synthetic hormone supplements, and schedule follow-up examinations (including blood tests) to monitor your cat's overall health and hormone levels. A modified diet containing reduced fat may also be recommended for your cat while they are recovering.

Most cats recover well from hypothyroidism, with a notable improvement in their health seen in just a short amount of time.
