Diagnosing hyperthyroidism in cats

Diagnosing hyperthyroidism in cats

For cats, hyperthyroidism must be diagnosed through a clinical evaluation, a physical check, and specific laboratory tests. Here different ways are given below to diagnosing process:

Past and Clinical signs: 

The first step in diagnosing a problem is to discuss your cat’s medical past and any apparent clinical signs. Cats that have hyperthyroidism often lose weight have a more intense hunger, drink more water, are restless, hyperactive, vomit, and have diarrhea.

Physical Exam: 

Your vet will do a physical exam to look for signs of hyperthyroidism that are generally present in animals. They might check the cat’s general health or feel for goiter, a swollen thyroid gland in the neck.

Blood Tests: 

One of the most essential parts of detecting hyperthyroidism is doing blood tests. The primary purpose of the blood test is to find out how much thyroid hormones are present, mostly thyroxine (T4) and triiodothyronine (T3). If you have high amounts of these hormones, you likely have hyperthyroidism.

Additional Tests: 

Other blood tests may be done to check the health of the kidneys, liver, and body as a whole. It’s essential to check on these organs as well because hyperthyroidism can have side effects on them.

Thyroid Imaging: 

Your vet may suggest imaging studies to prove that you have an enlarged thyroid gland and figure out where and how big it is. Ultrasound and scintigraphy are two popular ways to look at the thyroid. Ultrasound is a painless way to look at the thyroid gland, and scintigraphy, which uses a radioactive tracer, can show that the enlarged thyroid tissue is there and working.

Fine Needle Aspiration (FNA) Biopsy:

An FNA biopsy may be done if the diagnosis is unclear or other imaging data are not precise. A fine needle takes out a small piece of thyroid tissue to be analyzed. It can help prove that someone has hyperthyroidism and clear out other thyroid problems.

Your vet will be able to say for sure that your pet has hyperthyroidism once they have all the information they need. It is essential to work closely with your vet to get a correct evaluation and make a suitable treatment plan, whether that includes medicine, surgery, radioactive iodine therapy, changing your pet’s diet, or a mix of these.

Treatments for hyperthyroidism in cats

They can be given to cats in the form of pills or a gel that is put inside their ears. When taking medicine, it is essential to monitor thyroid levels and possible side effects regularly.

Therapy with radioactive iodine (I-131):

This is thought to be one of the best and most successful ways to treat hyperthyroidism. It uses a single shot of radioactive iodine to target and kill the tissue in the thyroid that is working too hard. This treatment is generally done in a particular place because it involves working with radioactive materials and keeping the cat away from other cats until the radiation levels are safe.


Another choice is a thyroidectomy, which is surgery to remove the thyroid gland(s). This is usually thought of when other treatments can’t be used, or medicine isn’t working right. Before surgery, you should talk to your vet about the possible risks and rewards.

Dietary Management: 

Hill’s Prescription Diet and other prescription meals low in iodine can help people with hyperthyroidism control their condition. These diets work by reducing the amount of iodine that the body needs to make thyroid hormones. Although they might not cure the illness, they can be used to treat it in the long run.

Supportive Care: 

Giving supportive care is as essential as the above mentioned methods. This includes taking care of any other health problems that may have come up because of hyperthyroidism, like heart disease or kidney disease. Your doctor can suggest any other medicines or treatments that might be helpful.
