Symptoms of Hyperthyroidism in Cats


Whenever the thyroid gland produces excessive thyroid hormones, hyperthyroidism occurs. Among cats over the age of eight, it would be the most prevalent endocrine illness to affect them. As the name implies, endocrine illness affects regions that produce or emit hormones.

Hyperthyroidism is nearly often induced by a benign thyroid tumour. There are two lobes upon every side of the butterfly-shaped thyroid hormone, which is situated inside the neck. When it comes to controlling the body’s metabolic rate, it’s crucial. An excessive quantity of thyroid hormones leads the cat’s body to operate at an unusually fast pace whenever the thyroid gland is overactive. Hyperthyroidism is a frequent illness in cats that is induced by the thyroid glands producing too much thyroid hormone. When cats reach the age of thirteen that is the time when hyperthyroidism is most frequent. Consult your vet immediately if you believe that your cat does have an inflamed gland in its neck. As a result, cats with hyperthyroidism can enjoy a happy and prosperous life.


When hyperthyroidism first develops, the symptoms might be mild, comparable to other common feline illnesses, such as diabetes. As the condition advances, the symptoms might become more severe and more difficult to treat. Among the symptoms are:

  • However, hyperthyroidism has indeed been proven to cause a reduction in your cat’s hunger as well as an increase in it. Additional symptoms include significant weight loss despite your cat’s high hunger.
  • If your cat has hyperthyroidism, this might be a clear indication of the condition. Hyperthyroidism is characterised by increased activity, sometimes to the point of hyperactivity. Symptoms include a rapid heartbeat. As a result of hyperthyroidism, there is also an increase in excessive thirst. So, it might potentially be a sign of a more serious condition.
  • There are two additional major signs of hyperthyroidism in your cat: frequent urination and vomiting.
  • Your cat’s hyperthyroidism might also induce diarrhoea. In addition to an untidy coat, hyperthyroidism in cats can manifest as anxiety, inability to sleep or violent behaviour changes.

Whenever you see any of such signs in your cat, then you should immediately take your cat to the doctor for a proper diagnosis. It’s best if one’s cat is medicated as soon as possible. To make your cat enjoy a long life, this condition should be controlled or eliminated. If you want to know more about these symptoms, you can connect online.

What will happen if these symptoms are left unaddressed?

Unfortunately, due to cats’ proclivity for hiding or masking indications of disease, hyperthyroidism might go undetected. It’s also easy to ignore because it’s more prevalent in elderly cats with certain other health problems that have common characteristics. Thyroid hormones impact nearly all of the internal tissues. Hyperthyroidism in cats might cause significant complications and even death if left unchecked. Thyroid hormones, for example, induce the heart to beat quicker and constrict more forcefully. This can impede the heart’s regular functioning and lead to cardiac arrest in a very short period of time.
