Hyperthyroidism is the most common hormonal abnormality in cats, causing the thyroid gland to become overactive and produce excess amounts of thyroid hormone. Fortunately, a more recent discovery has made the way to treat the disease easier for veterinarians, while also making the costs of treatment less expensive on the cat owner.
Traditional treatments included radioactive iodine treatment to inactivate the tumor cells that cause excess secretion of thyroid hormone, or medication to suppress hormone secretion. Several years ago, it was found that a limited iodine diet was just as effective as the traditional methods of treating hyperthyroidism in cats. The solution was revolutionary and substantially reduced the costs of treating this condition.
