Information You Must Know About Cat’s Hyperthyroidism

Many pet parents intend to have a feline that lives through its elderly years in excellent health and happiness. The most popular endocrine condition in felines is hyperthyroidism. As cats age, they become more prone. Hence, we decided to discuss cat hyperthyroidism, a necessary condition for cat guardians to be aware of. You can see below the vital facts regarding hyperthyroidism you must know.

What is hyperthyroidism?

Hyperthyroidism is also referred to as thyrotoxicosis. The overproduction of thyroid hormones is brought on by a swollen thyroid gland in a cat’s neck. The benign growth called an adenoma is the most common cause of bigger thyroid glands. Malignant thyroid adenocarcinomas create some very unusual cases of hyperthyroidism. Although the origin of feline hyperthyroidism is undiscovered, dietary lack or excesses and constant exposure to thyroid-disrupting substances may contribute.

Hyperthyroidism is a rampant issue that mainly impacts middle-aged and elderly cats. Because of the overall result of thyroid hormones, several health issues may develop due to thyroid disorder. Prepare a wellness plan for your pets to avoid these conditions. Search the internet to learn more.

What are the symptoms of a cat’s hyperthyroidism?

Hyperthyroidism in cats typically materializes itself in a vast array of indicators, several of which might be moderate initially but escalate as the condition worsens. Among the symptoms of feline hyperthyroidism are:

  • Diarrhea
  • Restlessness
  • Weight drop
  • Vomiting
  • Increased urination
  • Hyperactivity
  • Appetite stimulation

Any signs that your cat may be dealing with hyperthyroidism, regardless of how little, need an emergency visit to the veterinarian and start a therapy plan. Hyperthyroidism causes consistent weight reduction in cats if the condition is not taken care of. This might cause them to form hypertension because of their constantly increased core body temperature, heart rate, and respiratory rate, as well as their continuous frustration and restlessness.

How is a cat’s hyperthyroidism diagnosed?

If a vet senses a feline has a thyroid concern, they will physically examine and touch the feline’s neck to feel for a swollen thyroid gland. There are vet websites on the internet you can consult; visit their homepage to know more details. The following diagnostic procedures are ones your veterinarian may propose.

T4 Blood Test

T4 (thyroxine) levels that are unusually high are associated with hyperthyroidism. In certain conditions, further assessments of thyroid function can be required.

Complete blood count (CBC)

Anemia, swelling, infection, and platelet counts might all be determined using a full blood count.


This test finds signs of chronic renal illness and infection in the pet’s pee.

Chemistry Panel

To check for other disorders, such as chronic liver and renal damage or illness, it is required to have a total blood panel performed.

What are the treatments for a cat’s hyperthyroidism?

Therapy is required to restore the usual thyroid function in cats diagnosed with hyperthyroidism and reduce this problem’s symptoms. Thankfully, hyperthyroidism might be properly resolved. The following are a few of your treatment alternatives:


Thyroid hormone secretion may be controlled by routine medication. If your cat takes the drug, T4 testing is necessary until its thyroid level is normal. Once settled, your cat will require T4 testing to validate that no medication adjustments are required.


This pertains to the actual extraction of the thyroid gland.

Radioiodine Therapy

Radioactive iodine therapy for cats is a procedure for treating thyroid ailments by irradiating the affected gland with radioactive iodine. In most cases, this therapy must only be conducted once on a cat to eliminate the condition.

Dietary Supplements

Your cat can consume an iodine-restricted prescription diet plan. They can not be cured with other foods or treats. Your veterinarian might also consider checking kidney function and blood pressure.
