Hyperthyroidism in cats: signs, control and treatment

What is hyperthyroidism?

The thyroid gland, located in your cat’s neck, uses dietary iodine to produce thyroid hormones that help regulate important bodily functions, including:

  • Metabolism.
  • Body temperature.
  • Blood pressure.
  • Heart rate.
  • gastrointestinal function.

Hyperthyroidism is a fairly common endocrinological disorder in cats that is characterized by high levels of circulating thyroid hormones. In cats, hyperthyroidism is almost always associated with an overactive thyroid gland, which is most often diagnosed in older cats over the age of 10 years. If left untreated, hyperthyroidism can lead to serious and sometimes fatal effects on vital organs such as the heart and kidneys. The good news is that this disease is highly treatable and can be controlled with proper veterinary care.

If your cat has hyperthyroidism, the thyroid gland enlarges and produces excessive amounts of thyroid hormones.

Warning signs and symptoms of hyperthyroidism in cats

Signs of hyperthyroidism can vary in severity depending on how long the pet has been sick. If your pet shows any of the following signs, contact your veterinarian immediately:

  • Weight loss.
  • Increased appetite.
  • Diarrhea and/or vomiting.
  • Strong thirst.
  • Poor condition of the skin and coat.
  • Hyperactivity.

Cats with chronic renal failure and diabetes mellitus have some signs similar to hyperthyroidism. Your veterinarian may need to perform additional tests to rule out these diseases and make an accurate diagnosis.

Fight against hyperthyroidism

There are four possible treatment options for cats with hyperthyroidism:

  1. Daily Nutrition: Limiting dietary iodine intake reduces thyroid hormone production.
  2. Daily medications: Antithyroid medications suppress the production of thyroid hormones.
  3. Radioactive iodine therapy: for the treatment of abnormal thyroid tissue.
  4. Surgical intervention: removal of the affected thyroid tissue.

Treatment: the importance of nutrition

The health of an old cat and her condition in general depends largely on the food she eats. A balanced diet is an essential part of an active, healthy lifestyle. For an accurate diagnosis and treatment options, always consult your veterinarian and ask them to recommend the best food for your cat’s thyroid health.
