What is radioactive iodine treatment for hyperthyroidism?
What is Radioactive Iodine Treatment? Radioactive iodine is a procedure that is often used to treat hyperthyroidism. The entire goal of the procedure is to put radioactive iodine molecules into your body with the sole purpose of destroying your thyroid gland. Radioactive iodine works by taking advantage of the physiology in your body (1).
Is I-131 radioactive?
Iodine-131 (I-131) is radioactive. Radiation can be measured around your body and I-131 is present in your skin oil and sweat. Whatever touches your skin will pick up a small amount of radiation. The I-131 leaves your body through your urine primarily.
What are the risks of radioactive iodine treatment?
Because the radioactive iodine used (known as iodine 131) may expose those around you to the effects of radiation (and theoretically negatively affect their thyroid glands), you will be given guidelines on how to prevent such exposure.
How long does it take for radioactive iodine to absorb?
Since thyroid cells can’t tell the difference between radioactive and non-radioactive iodine, they absorb it quickly. Any radioactive iodine not absorbed by the thyroid is excreted by the body within a few days. When used for diagnosis, very small amounts of radioactive iodine help highlight the areas where cancerous thyroid cells are on scans.
What are side effects of radioactive iodine therapy I 131?
What are the side effects of radioactive iodine?Neck tenderness and swelling.Nausea.Swollen salivary glands.Loss of taste or taste change.Dry mouth/insufficient salivary production.Dry eyes.Excessive tearing from the eyes.

Treatment of hyperthyroidism with RAI or anti-thyroid medications is associated with an increased risk of gaining weight and even developing obesity. This risk is slightly higher with RAI therapy compared to medications.
How long does iodine 131 stay in the body?
Most of the radioiodine not collected by your thyroid gland will be eliminated during the first two days after your treatment. It leaves the body primarily through your urine, but very small amounts may leave in your saliva, sweat and during a bowel movement.

You are also required to self isolate for 7 days after your radioiodine treatment in order to minimise the risk of contracting COVID-19 whilst there is still a large amount of radioactivity in your body. A small proportion of people with COVID-19 may become very unwell and require admission to hospital.
Can thyroid grow back after radioactive iodine treatment?
Once hypothyroidism has been achieved, it is usually irreversible with the patient requiring lifelong thyroid replacement. Early recurrences are reported in 20–54% of cases within 3–6 months, which can be due to inadequate RAI treatment or early Marine Lenhart syndrome.
What is iodine used for?
Iodine, in the form of iodide, is made into two radioactive forms of iodine that are commonly used in patients with thyroid diseases: I-123 ( harmless to thyroid cells) and I-131 ( destroys thyroid cells ). The radiation emitted by each of these forms of iodine can be detected from outside the patient to gain information about thyroid function ...
What is the purpose of I-131?
THYROID CANCER – Large doses of I-131 are used to destroy thyroid cancer cells (see Thyroid Cancer brochure ). This is performed after the remaining thyroid cells ( including any cancer cells) are stimulated by raising TSH levels by either withdrawing the thyroid hormone pills or by treating with recombinant human TSH.
What is the I-123 isotope used for?
I-123 is the usual isotope used to take pictures and determine the activity of the intact thyroid gland ( Thyroid Scan and Radioactive Iodine Uptake, RAIU ), since it is harmless to thyroid cells. No special radiation precautions are necessary after a thyroid scan or RAIU using I-123. I-131 can also be used to take pictures of the thyroid gland, ...
Why is iodine important for the thyroid gland?
Iodine is essential for proper function of the thyroid gland, which use s it to make the thyroid hormones. The thyroid is equipped with an active system or “pump” for moving iodine into its cells, where it is concentrated as iodide. The thyroid gland is the only tissue in the body that takes up and holds onto iodine.
Is rai safe for X-rays?
RAI is safe to use in individuals who have had allergic reactions to seafood or X-ray contrast agents, since the reaction is to the compound containing io dine, not the iodine itself. RAI is given by mouth in pill or liquid form.
When can you stop breast feeding after I-131?
This protects the baby who would otherwise receive radioactive milk and the mother’s breasts which concentrate RAI. Breastfeeding must be stopped at least 6 weeks before administration of I-131 treatment and should not be restarted after administration of RAI, but can be safely done after future pregnancies.
Can RAI cause thyroid cancer?
Hypothyroidism is a common side effect of RAI for hyperthyroidism and always seen after RAI for thyroid cancer. This is usually easily treated with thyroid hormone replacement (see Hypothyroidism brochure ). Some studies suggest a slight increase in thyroid cancers may be seen after RAI treatment for hyperthyroidism.
How long does radioactive iodine affect sperm count?
Important to men is the fact that radioactive iodine can cause short-term reductions in sperm count for up to 2 years after your procedure (8). This may or may not be important to you based on your age, your gender, and whether or not fertility is something you are interested in but, again, it's worth knowing about.

Does RAI cause weight gain?

How to avoid radiation?
Here are some ways to minimize radiation risks to other people (and pets) after you have had RAI treatment: 1 Stay at least six feet away from other people, including members of the public, family members, and co-workers, for three to 11 days.
