Iodine-131 treatment for hyperthyroidism is generally about 2600 RMB in Henan, but before doing this test, we usually need to do iodine absorption rate, nail function, blood routine, liver function, kidney function and other related auxiliary tests to clarify whether the patient can do this treatment, so the total cost comes down to about 3000 RMB. There are three types of treatment for hyperthyroidism, including drug therapy, iodine-131 therapy and surgery, each of which has its own relative indications and contraindications. Iodine-131 treatment is contraindicated for pregnant and breastfeeding women, so this must be noted before having this test. The biggest side effect of Iodine-131 treatment is the possibility of developing hypothyroidism, and the probability of developing hypothyroidism gradually increases with time, so it is important to consider this treatment carefully before doing it.
