                  If the response to treatment is correct, the patient’s condition will gradually improve during the first 1-3 months<\/b>. In 85% <\/b>of patients, thyroid hormone levels will normalize within a month, and in 95%<\/b> of patients within 3 months. If thyroid hormone levels remain high after 4 months, the cat may need to repeat radioactive iodine therapy. Immediately after radioiodine therapy, cats usually do not need any further treatment. <\/p>

                  Transient hypothyroidism may occur, causing a slight decrease in tT4 levels below the minimum reference range of the laboratory where the blood is tested. This condition is not pathological\/life-threatening if it does not last longer than 4-6 months. <\/p>

                  The cat’s blood will need to be checked 1, 3, and 6 months after therapy\u2014we are mainly interested in kidney parameters (SDMA, creatinine), tT4, and TSH. Kidney parameters are important for the early detection of masked CKD, and tT4 and TSH together can detect hypothyroidism caused by an excessively high dose of radioiodine, which can happen even with accurate dose calculation. It is very important to detect hypothyroidism and start treating it in time, before it causes kidney damage and the subsequent development of CKD. <\/p>

                  In cats with CKD Iris stage 1-2, tT4 and TSH should be checked 14 days after radioiodine administration, as untreated hypothyroidism could lead to a significant reduction in glomerular filtration and, as a result, the development of renal failure. Therefore, levothyroxine supplementation should be started early in these cats. <\/p>

                  If a cat shows typical clinical signs of hyperthyroidism (weight loss, diarrhea, vomiting), urgent tT4 testing is necessary.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
