These hormones control your metabolism, heart health, and more. To make thyroid hormones, your thyroid takes up iodine in small amounts. Without iodine, thyroid hormone production can decrease. You can get enough iodine from your diet by eating dairy products, fortified foods, and salt water fish. Iodine is also available in plant foods that grow in naturally iodine-rich soil.
You also can get the mineral by seasoning your food with iodized salt. While iodine promotes overall thyroid health, too much iodine can have a negative effect on the thyroid gland. A goiter is an enlarged thyroid gland. Your thyroid may become enlarged as a result from either hypothyroidism or hyperthyroidism.
Hyperthyroidism is an overactive thyroid gland. Non-cancerous thyroid nodules cysts can also cause thyroid gland enlargement. Sometimes a goiter develops as a direct response to iodine deficiency. Your doctor may recommend a special type of iodine called radioactive iodine to treat an overactive thyroid gland. Also called radioiodine, this medication is taken by mouth.
The risk with radioactive iodine is that it can destroy too many thyroid cells. This can decrease the amount of hormone production, leading to hypothyroidism. For this reason, radioactive iodine is usually only recommended after anti-thyroid drugs have failed. Radioactive iodine is not the same thing as iodine supplements. You should never take iodine supplements for hyperthyroidism. Radioiodine may also be a possible treatment option for thyroid cancer. It works in much the same way as hyperthyroid treatment.
When you take radioactive iodine orally, the medication destroys thyroid cells, including cancerous ones. It may be used as a treatment following thyroid surgery to make sure all cancerous cells have been removed from the body.
According to the American Cancer Society , radioactive iodine treatments significantly improve the chances of survival for people with thyroid cancer. You need more iodine in pregnancy. The recommended daily intake of iodine during pregnancy is mcg. By comparison, the recommended amount in non-pregnant adults is mcg a day. The recommended daily amount of iodine while nursing is mcg.
The same neurological benefits of iodine during pregnancy may extend to healthy brain function during childhood. This also includes a reduced risk of intellectual disability.
It is likely your child gets all the iodine they need through their diet, but if you have any questions about their iodine intake, talk to their pediatrician. As with brain development, iodine during pregnancy is associated with a healthy birth weight. One study of pregnant women with goiters found that mg of iodine taken daily for six to eight weeks was helpful in correcting goiters related to iodine deficiency.
In turn, there was an overall improvement in birth weight in newborns. In fact, taking iodine unnecessarily can cause health issues. This non-cancerous condition is most common in women of reproductive age, and it can cause painful breast lumps.
Only take iodine for this condition if your doctor specifically recommends it. Otherwise, you could be at risk of side effects from iodine toxicity.
Iodine is just one method of water disinfection. Two percent liquid iodine tincture may be added to water in five-drop increments per one quart of clear water.
If the water is cloudy, add ten drops per quart. In the case of nuclear emergencies, the Centers for Disease Control and Prevention recommends the use of potassium iodide KI to protect the thyroid gland from radiation injuries. These are available in tablet and liquid formulas.
While not completely foolproof, the sooner KI is taken, the better the thyroid is thought to be protected in the event of this kind of emergency. There are serious risks associated with KI, including gastrointestinal upset, inflammation, and allergic reaction.
Your risk for complications is higher if you already have thyroid disease. Iodine can be used topically in a liquid form to help treat and prevent infections. It works by killing bacteria in and around mild cuts and scrapes. Topical iodine should not be used on newborn babies. Follow your doctor's orders or the directions on the label.
