What Does Iodine Do To The Thyroid

What Are The Symptoms Of Hyperthyroidism

How Does Iodine Cause Thyroid Disease Exactly?

The symptoms of hyperthyroidism can vary from person to person and may include:

  • Nervousness or irritability
  • Imaging tests, such as a thyroid scan, ultrasound, or radioactive iodine uptake test. A radioactive iodine uptake test measures how much radioactive iodine your thyroid takes up from your blood after you swallow a small amount of it.

I Am Concerned About The Use Of Salt In My Diet

Salt is a necessary part of a healthy diet. Some authorities advocate decreasing the intake of salt to prevent high blood pressure and reduce the incidence of cardiovascular disease. As most of the salt in the Australian diet comes from processed foods, The ATF suggests reducing salt intake to as low as possible and ensuring any salt used is iodised salt.

Types Of Thyroid Problems

Hopefully, you’re beginning to get the idea that there are MANY things that can go wrong with your thyroid gland.

The good news is that some of the problems associated with your thyroid have no effect on thyroid hormone production.

What does that mean?

It means that even if you have a condition such as thyroid cancer or a thyroid nodule, there’s a low chance that it will interfere with thyroid function in your body.

That means you probably won’t have the symptoms we discussed above.

But, on the other hand, there are some conditions which primarily do alter your ability to produce thyroid hormone.

These conditions, such as Hashimoto’s thyroiditis, WILL cause symptoms.

To give you a better idea of what can go wrong with your thyroid I’ve included some of the most common problems below:

Figuring out what is wrong with your thyroid is of utmost priority.

When you go to your Doctors office make sure you walk out with a diagnosis or at least an idea as to what is going on.

If you don’t then you may end up frustrated without any real clear idea how to treat your issue.

Answers To All Your Thyroid Questions

Did you know that every cell in your body is affected by thyroid hormones? Optimal thyroid health helps you feel energetic and motivated, sleep well, keep your hormones balanced, and even digest your food. Lets explore how the thyroid gland works, and why keeping it healthy is important.

Pregnant And Breastfeeding Women

Ultimate Guide To Hypothyroidism Causes and Treatment

The American Thyroid Association recommends that all pregnant and breastfeeding women in the United States and Canada take a prenatal vitamin containing 150 mcg of iodine a day as part of an overall recommended intake of 220 mcg/day and 290 mg/day, respectively. Excess iodine, however, can be particularly dangerous in these women.

When Should I See A Doctor About Iodine Deficiency

If youre concerned that your diet lacks iodine, or if you experience symptoms of hypothyroidism, hyperthyroidism or goiter, its a good idea to see a health care professional to have your thyroid checked.

In general, Narang recommends against self-diagnosis when it comes to taking iodine pills or eating copious amounts of iodine-rich food.

I do not recommend taking an iodine supplement without checking with your doctor. In fact, it can do more harm than good, she says.

Can You Consume Too Much Iodine

While iodine is essential to many basic functions of the body, there can be too much of a good thing.

High contents of iodine can cause hyperthyroidism, a goiter, or rarely, can initiate hypothyroidism, Narang says. Consuming too much iodine can also cause inflammation of the thyroid gland and thyroid cancer.

Here are the daily upper limits for iodine, as supplied by the NIH.

Life Stage


1,100 mcg

Iodine poisoning, or iodine toxicity, can occur, but it is rare and usually cannot happen through food intake alone. Reported fatal doses have varied from 200 mg to more than 20 g .

Symptoms can include abdominal pain, delirium or stupor, diarrhea, fever, gum and tooth soreness, metallic taste in mouth, mouth and throat burning, not urinating, rash, thirst and vomiting.

Seek immediate help if you suspect iodine poisoning. Call 911 or the national Poison Help hotline at 1-800-222-1222.

Protection From Nuclear Fallout

In the case of nuclear emergencies, the Centers for Disease Control and Prevention recommends the use of potassium iodide 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. Youre also at increased risk for thyroid disease. Your risk for complications is higher if you already have thyroid disease.

The Big Question: Do I Need Medication If I Take Iodine And Selenium

Do you have an IODINE deficiency? IODINE, your THYROID and weight

Many of us want natural, practical solutions for our thyroid health. So it’s common to wonder if Iodine and Selenium could be that option.

According to best-selling author of “Iodine: Why You Can’t Live Without It,” Dr. David Brownstein, the short answer is “maybe.” As explained in his book, Brownstein has worked with thousands of patients who used a combination of Iodine, Selenium, and other minerals in combination with other medications.

Over the years, he observed three scenarios for his patients who supplemented with Iodine:

  • Some stayed at the same thyroid medication dosage
  • Some were able to lower their medication
  • Some were able to go off their medication

However, Dr. Brownstein said there was no way to predict what his patients would need until he worked with them. That’s why a knowledgeable doctor is so important.

As you can see, Iodine and Selenium are essential minerals for people who are looking to support thyroid function naturally.

Assessment Of Iodine Intake

The relative iodine sufficiency of populations is routinely examined by measuring UI excretion. Although assessment of UI provides a useful index of population iodine intake, the value obtained reflects recent dietary intake and is not useful for determining the long-term iodine status of an individual. Another possible pitfall in investigating iodine sufficiency is that population iodine status is commonly established by measuring urine samples from school-aged children. This can often yield misleading results when applied to adults, particularly pregnant women, as milk consumption, a major source of dietary iodine, is typically greater in school-aged children .

An individuals ability to produce adequate levels of thyroid hormones is dependent on iodine stores built up and maintained over a period of time. For assessment of population iodine status, the WHO recommends a population median UI value of 100 µg/L for the general population and 150 µg/L for pregnant or lactating women . Populations with median UI values < 100 µg/L are judged deficient. The UI distribution is more informative than the percent UI < 100 µg/L with a recommendation that not > 20% of samples should be < 50 g/L .The accuracy of UI can be improved by collecting repeat samples to correct for intra-individual variation providing a more accurate indication of an estimated average requirement for iodine .

Their Ingredients And Effects Are Surprisingand Sometimes Harmful

Weight gain, fatigue, brain fog. These are all hallmark symptoms of hypothyroidism, a condition in which the thyroid, a small gland at the front of your neck, slows down or stops making the hormone thyroxine that helps keep your metabolism up to speed. If you are diagnosed with hypothyroidism , a doctor may give you a prescription for levothyroxine . This medication contains synthetic thyroid hormone that can correct the hormone deficiency and improve your symptoms.

Unfortunately, these unwelcome symptoms are not specific for hypothyroidism, but are also part and parcel of the natural aging process, and can affect people with normally functioning thyroid glands, says endocrinologist and Consumer Reports chief medical adviser Marvin M. Lipman, M.D. Less than 2 percent of people have hypothyroidism, Lipman says. Nevertheless, people who are desperate to lose weight and feel more energetic turn to supplements that are marketed to boost metabolism and energy naturally. But experts warn that taking these thyroid supplements is a bad idea. Heres why:

How Is Iodine Deficiency Diagnosed

Iodine is released through the urine, so iodine deficiency is almost always diagnosed across populations by measuring iodine amounts in municipal urine samples, and not by testing individuals.

A median urinary iodine concentration less than 100 mcg/L in nonpregnant people, and less than 150 mcg/L in pregnant people, is considered iodine deficient.

If one needs to be monitored for iodine for medical reasons, a urine or blood test can be performed for an individual iodine reading.

What Does My Thyroid Do

Do You Know The Importance Of Iodine And Your Thyroid ...

Your thyroid gland is a critical part of your endocrine system. Its purpose is to secrete thyroid hormones that:

  • Control the metabolic rate of almost all cells in the body
  • Control the metabolism of fat and carbohydrates
  • Boost protein synthesis
  • Regulate heart rate and blood flow to organs
  • Are important for energy production and oxygen consumption in cells
  • Promote linear growth and brain development in children
  • Are needed for normal reproductive function in adults
  • Are important in bone and calcium metabolism

When Do You Have Radioactive Iodine

You might have radioactive iodine treatment:

  • after surgery, to kill any cancer cells that may have been left behind
  • to treat thyroid cancer that has spread
  • to treat thyroid cancer that has come back after it was first treated

You may only need to have this treatment once. But it can be repeated every 3 months if needed, until there is no sign of any thyroid cancer on your scans.

Thyroid Cancer Risk & Iodine

What Does Iodine Do For Your Thyroid? What do you do if you have an iodine deficiency?

This is a dangerous one that I really want to talk about. As I began diving more into the research behind iodine, the research done across the globe has made it more and more clear that increased amounts of iodine can correlate to increase instances of thyroid cancer developing in certain populations.

Heres what research has found in:

  • Australia, iodine supplementation in salt lead to a doubling of thyroid cancer rates.4
  • Sweden, a higher intake of iodine correlated with higher risk of papillary thyroid carcinomas.5
  • Korea, rates of thyroid cancer elevated 10 fold in relation to increased iodine intake.6

Key Insight: It really is as simple as this the higher intake of iodine there is, the greater risk that we have for thyroid cancer.

What Is The Treatment Of Hyperthyroidism

The goal of treatment is to lower the amount of thyroid hormones in the body. Treatment options include:

  • Radioactive iodine . Also called radioiodine. RAI is a common and long-used treatment for hyperthyroidism.
  • Surgery. This treatment removes the thyroid gland with surgery .
  • Antithyroid drugs. These medicines are given for months or even years to lower the levels of thyroid hormone. Sometimes, patients are prescribed these medications in preparation for RAI or surgery.

Does Iodine Help Thyroid Nodules And Goiter

Can iodine help with thyroid nodules and goiter? This is a common question I will answer today. Let me tell you about a patient who had thyroid nodules that were completely resolved over 18 months. Im Dr. Tom Rofrano from the Natural Medicine Clinic in Palm Beach Gardens, Florida. I have seen over 100,000 patient visits over the last 35 years. Many of those have gut and thyroid issues including nodules and Hashimotos.

I recently saw a 69-year-old female with thyroid nodules and Hashimotos who had been on medication over 10 years and was feeling miserable. She suffered from the usual thyroid symptoms of fatigue, weight gain, aches and pains, brain fog, and digestive issues. In the initial evaluation, I typically look for underlying root causes including these five main areas: deficiencies, toxins, infections, hormones, and food reactions.

How Does Radioactive Iodine Treat Thyroid Cancer

The most common types of thyroid cancer can usually be treated with large doses of radioactive iodine. The therapy is usually given after removal of the thyroid gland to destroy any remaining thyroid tissue.

A tracer dose of radioactive iodine can also be used to track remaining thyroid tissue and/or cancer that could have spread to other parts of the body. These tests show if iodine concentrates in areas that contain thyroid cancer, and whether large amounts of RAI are needed to destroy the tumor implants.

It really depends on whats in the supplement. If youre lacking in minerals and nutrients, it can take a few days for supplements to kick in. From personal and clinical experience, iodine can work within days. Its a great source of energy production because of its ability to enhance the thyroid and metabolism, which drives energy. Many people are so iodine deficient that when they start supplementing it they notice a difference in energy and mental clarity within a few days. Generally speaking, it takes around three to six weeks for noticeable changes.

Trouble Learning And Remembering

An iodine deficiency may affect your ability to learn and remember .

A study including over 1,000 adults found that those with higher thyroid hormone levels performed better on learning and memory tests, compared to those with lower thyroid hormone levels .

Thyroid hormones help your brain grow and develop. Thats why an iodine deficiency, which is required to make thyroid hormones, can reduce brain development .

In fact, studies have found that the hippocampus, the part of the brain that controls long-term memory, appears to be smaller in people with low thyroid hormone levels .


An iodine deficiency at any age may cause you to struggle to learn and remember things. One possible reason for this might be an underdeveloped brain.

How Radioactive Iodine Works

Radioactive iodine is available in an oral pill, so you won’t need to be hospitalized. After you take the pill, your doctor will recommend drinking lots of fluids to prompt the release of the radioactive iodine through your urine.

Fortunately, radioactive iodine therapy is targeted to treat only your thyroid gland. Thyroid cells are the main cells in the body that can absorb iodine, so there is very little radiation exposure to the rest of your body’s cells. When the thyroid cells absorb the radiation, they are damaged or destroyed.

Approximately 90% of patients need only one dose before they are cured of their hyperthyroidism. Though you may only need a single dose, it may take up to six months before the medication fully destroys all or part of the thyroid. Fortunately, most patients experience reduced symptoms about a month after treatment.

If your symptoms persist 6 months after treatment, you may need a second dose. In the rarest of cases, some patients will not benefit from a second dose and may instead require .

High levels can inflame your thyroid gland and can cause some of the same symptoms that low levels do, including a goiter. A very large dose, like several grams of iodine at once, could put you in a coma. It also might burn your stomach, throat, or mouth, and cause a weak pulse, nausea, vomiting, and diarrhea. Even ânormalâ levels can cause problems if your body is used to much less iodine in your diet or you already have thyroid problems.

I-123 is the usual isotope used to take pictures and determine the activity of the intact thyroid gland , 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, although it is rarely used due to the harmful effects it has on thyroid cells.
