Treatments Available for Hyperthyroidism


Thyroid hormones are overproduced by the thyroid glands, resulting in hyperthyroidism. Among cats over the age of eight, it would be the most prevalent endocrine illness to affect them. Hyperthyroidism is nearly often caused by a benign thyroid tumor. There are two lobes upon every side of the thyroid glands, which are situated inside the neck. When it comes to controlling the body’s metabolic rate, it’s crucial. An inadequate quantity of thyroid hormones leads the cat’s organs to operate at an unusually fast pace whenever the thyroid gland is overactive.

The Diagnosis

On the basis of clinical symptoms, a potential thyroid lump, and serum thyroid tests, a diagnosis is made. Ninety percent of cats that are suffering from hyperthyroidism had increased total T4 levels, according to balancing dialysis. It is recommended that a cat with hyperthyroidism with adequate T4 be retested the next day that’s because the amount of T4 might vary. With time, T4 values in cats lacking hyperthyroidism begin to drift towards the lower average limits. It is recommended to do a free T4 test on a cat suffering from hyperthyroidism symptoms and with a high normal T4 concentration in order to narrow down the diagnosis.

In general, cats with hyperthyroidism have three treatment options:

  1. Medications

Cats suffering from hyperthyroidism can be cured with medicines that prevent the thyroid from oversupplying hormones, according to the Mayo Clinic. Thyroid-inhibiting medicine isn’t a treatment for this condition, but it’s necessary throughout the cat’s whole life. It’s a good thing that these drugs are typically easily available and might be inexpensive depending on the cat family’s financial situation. This therapy does, however, need a significant amount of time and money to complete. Some cats experience adverse effects including fever, vomiting, or drowsiness after taking these medicines.

  1. Surgical treatments

Certain cats may need to have their thyroid glands surgically removed. This condition can be treated with surgery and without the need for long-term medications. Every surgical procedure, even those on elderly cats or those with health concerns due to hyperthyroidism or even other illnesses is not without danger. Treatment on the thyroid carries its own set of dangers. Due to the thyroid glands’ location in the neck, it is possible for other organs to be injured during the surgery. Additionally, if a big piece or the whole thyroid is eliminated, the cat will require thyroid hormone supplementation for the rest of his life.

  1. Treatment with radioactive iodine

Using this method, a radioactive iodine dosage is administered to the cat. Thyroid cells that are hyperactive are destroyed by this iodine without causing harm to the adjacent organs. In just a week or two after receiving this medication, cats’ thyroid hormone amounts can return to normal. Thyroid hormone deficiency can also occur in cats. Taking a thyroid hormone prescription may be essential if this is the case. An experienced veterinarian might help you choose the best line of treatment if hyperthyroidism has been detected in your cat.  Visit here to knowmore about the treatments in detail.
