Everything You Must Know About Cat’s Hyperthyroidism

Having a cat that endures its elderly years in excellent health and happiness is a target of many pet owners. The widespread endocrine problem in felines is hyperthyroidism. As cats age, they get more vulnerable. Hence, we decided to tackle hyperthyroidism in cats, a necessary problem for feline parents to be familiar with. You can see below the essential information concerning hyperthyroidism you must know.

What is hyperthyroidism?

Hyperthyroidism is also known as thyrotoxicosis. The overproduction of thyroid hormones is brought on by an inflamed thyroid gland in a feline’s neck. The benign lump referred to as an adenoma is the most common reason for enlarged thyroid glands. Malignant thyroid adenocarcinomas create some extremely uncommon instances of hyperthyroidism. Although the origin of feline hyperthyroidism is unknown, dietary lack or excesses and persistent exposure to thyroid-disrupting substances might contribute.

Hyperthyroidism is a widespread problem that mostly influences middle-aged and senior felines. Because of the overall effect of thyroid hormones, many health problems might occur due to thyroid conditions. Prepare a wellness plan for your pets to avoid these conditions.

What are the symptoms of a cat’s hyperthyroidism?

Hyperthyroidism in felines typically manifests itself in a wide variety of symptoms, a few of which may be mild at first but escalate as the condition worsens. Among the indicators of feline hyperthyroidism are:

  • Diarrhea
  • Restlessness
  • Weight reduction
  • Vomiting
  • Increased peeing
  • Hyperactivity
  • Appetite stimulation

Any indicators that your feline may be coping with hyperthyroidism, despite how small, require an urgent trip to the vet and begin a therapy method. Hyperthyroidism triggers constant weight reduction in cats if the problem is not managed. This might trigger them to develop hypertension because of their constantly high core body temperature, heart rate, and breathing rate, and constant anxiety and restlessness.

If a veterinarian feels a feline has a thyroid issue, they will physically examine and touch the feline’s neck to feel for an inflamed thyroid gland. The following diagnostic techniques are ones your veterinarian may suggest.

T4 Blood Test

T4 (thyroxine) amounts that are unusually high are associated with hyperthyroidism. In certain circumstances, additional testing of thyroid function can be needed.

Complete blood count (CBC)

Anemia, swelling, infection, and platelet counts might all be figured out with a full blood count.


This assessment searches for signs of chronic kidney condition and infection in the cat’s urine.

Chemistry Panel

To examine for other conditions, such as severe liver and kidney damage or illness, it is essential to have a complete blood panel performed.

What are the treatments for a cat’s hyperthyroidism?

Therapy is needed to recover normal thyroid function in felines diagnosed with hyperthyroidism and lower this condition’s symptoms. Fortunately, hyperthyroidism may be effectively managed. The following are some of your therapy alternatives:


Thyroid hormone creation might be regulated by regular medication. If your cat takes medication, T4 testing is essential until its thyroid amount is regular. When maintained, your feline will need T4 testing to validate that no medical modifications are needed.

Radioiodine Therapy

Cat iodine radioactive treatment is a method of handling thyroid ailment by irradiating the affected gland with radioactive iodine. Mostly, this therapy must only be administered once to a cat to eradicate the condition.

Dietary Supplements
