What Natural Home Remedies And Supplements Treat Thyroid Problems

Thyroid Self-Test Medical Course

Supplements that contain large amounts of iodine such as seaweed can make thyroid hormone levels go very high or very low if you have nodular goiter and a history of an autoimmune thyroid condition such as Hashimotoâs thyroiditis or Gravesâ disease.

There is no scientific evidence that herbal supplements, yoga poses, natural thyroid treatments, or natural thyroid remedies improve thyroid health and function. Dietary supplements are not regulated by any agency and therefore there is no quality control of these supplements. It is not recommended that any supplement be taken for thyroid health.

Donât take supplements for your thyroid problem without consulting a doctor.

Hyperthyroidism: Diagnosis And Treatment

IGOR KRAVETS, MD, Stony Brook University School of Medicine, Stony Brook, New York

Am Fam Physician. 2016 Mar 1 93:363-370.

Patient information: See related handout on overactive thyroid gland , written by the author of this article.

Hyperthyroidism is an excessive concentration of thyroid hormones in tissues caused by increased synthesis of thyroid hormones, excessive release of preformed thyroid hormones, or an endogenous or exogenous extrathyroidal source. The most common causes of an excessive production of thyroid hormones are Graves disease, toxic multinodular goiter, and toxic adenoma. The most common cause of an excessive passive release of thyroid hormones is painless thyroiditis, although its clinical presentation is the same as with other causes. Hyperthyroidism caused by overproduction of thyroid hormones can be treated with antithyroid medications , radioactive iodine ablation of the thyroid gland, or surgical thyroidectomy. Radioactive iodine ablation is the most widely used treatment in the United States. The choice of treatment depends on the underlying diagnosis, the presence of contraindications to a particular treatment modality, the severity of hyperthyroidism, and the patient’s preference.


The choice of treatment modality for hyperthyroidism caused by overproduction of thyroid hormones depends on the patient’s age, symptoms, comorbidities, and preference.


Natural Remedies For Hyperthyroidism

Hyperthyroidism occurs when too much thyroid hormone is produced and secreted into the bloodstream. This can cause the metabolism and heart rate to speed up, leading to diarrhea, fatigue, high blood pressure, and sleep problems.

Hyperthyroidism is commonly caused by Graves disease, throat cancer, or too much iodine. Modifying your diet by reducing iodine intake can help. Foods that are low in iodine include:

  • Egg whites
  • Fresh fruit and unsalted nuts
  • Homemade bread without salt, eggs, or dairy
  • Maple syrup and honey
  • Oats and potatoes

Studies have shown that cruciferous vegetables have properties that can prevent the thyroid from using iodine. Cruciferous vegetables are leafy greens that belong to the cabbage family. These greens may be beneficial:

  • Broccoli and bamboo shoots
  • Brussels sprouts and bok choy
  • Cauliflower and kale
  • Collard greens, cassava, mustard, and rutabaga

Low iron levels can compromise thyroid health. Other beneficial vitamins and minerals may include calcium, vitamin D, selenium, and zinc. Hyperthyroidism can reduce bone mass, but calcium and vitamin D can help to restore it. Selenium may help to deter cell damage. Finally, zinc is essential for converting food into energy. To get thyroid-friendly nutrients, supplement your diet with:

  • Green leafy vegetables
  • Nuts, lentils, and dried beans
  • Red meat and poultry

You Have Depression Memory Issues Nervousness Or Irritability

This is one of the most frustrating things about not being diagnosed with a thyroid issue. You may be depressed, have memory issues, or be annoyed or panicky all the time, and you think it’s psychological instead of physical. Dr. Romy Block, a Chicago-area endocrinologist, told me that “mood changes ” can indicate that your thyroid is out of whack. The Mayo Clinic cites depression as a symptom of hypothyroidism, but it can also manifest in hyperthyroidism, as one counselor wrote in Psychology Today, and as a patient case study on the National Center for Biotechnology Information’s website shows.

Other things to look out for include “nervousness, anxiety and irritability,” which the Mayo Clinic says may be a sign of hyperthyroidism. And Dr. Block told me that “a common symptom of hypothyroidism is memory loss,” so if you feel like you’re being too forgetful these days, there might be a reason.

When To Have A Thyroid Function Blood Test

These 5 Tests Can Detect Hyperthyroidism Or Overactive ...

You can meet with us and ask if you should have a blood test if:

  • Your neck is swelling or thickening
  • You experience symptoms that your thyroid is over- or under-active
  • You notice the irregular heart rate
  • You have fertility problems
  • Your family members have had autoimmune disorders

Other reasons that should prompt you to get a thyroid function test if you

  • Do not feel well after giving birth
  • Have a family history of thyroid disorders, a history of postpartum thyrodism or type 1 diabetes and you are in your early stage of pregnancy, or you are planning to become pregnant

We usually advise the following people to get tested for thyroid function at least once a year or more frequently at your doctors advice:

  • Those that are diagnosed with a thyroid disorder
  • Those that have been treated before for an overactive thyroid
  • Those that have had irradiation to the head and neck that preceded a surgery for cancer of the head and neck
  • Those that want to begin treatment with Amiodarone or Lithium. This should be done 6-12 months during and 12 months after the treatment.

We also advise people with Turner syndrome, Downs syndrome and Addisons disease or other autoimmune diseases to get regularly tested.

What Does My Thyroid Do

Located at the front of your neck, the thyroid is a butterfly-shaped gland. Glands are organs that can be found all over your body. Some of your glands create and release hormones substances that help your body function and grow. The thyroid gland plays a big part in many of your bodys main functions, including:

  • Regulating your body temperature.
  • Controlling your heart rate.
  • Controlling your metabolism .

When your thyroid gland is working correctly, your body is in balance, and all of your systems function properly. If your thyroid stops working the way its meant to creating too much or too little thyroid hormones it can impact your entire body.

What Is Reverse T3

Reverse T3 is a biologically inactive form of T3. Normally, when T4 is converted to T3 in the body, a certain percentage of the T3 is in the form of RT3. When the body is under stress, such as during a serious illness, thyroid hormone levels may be outside of normal ranges even though there is no thyroid disease present. RT3 may be elevated in non-thyroidal conditions, particularly the stress of illness. It is generally recommended that thyroid testing be avoided in hospitalized patients or deferred until after a person has recovered from an acute illness. Use of the RT3 test remains controversial, and it is not widely requested.

What Is The Thyroid Gland And What Does It Do

The thyroid gland is the gland that is located below your Adams apple just in front of your neck. This gland has two lobes with each of them on each side of the windpipe, and they are connected by a small tissue called isthmus. This gland secretes two major hormones into your blood. The first hormone is thyroxine, which is often called T4 and contains four atoms of iodine. This hormone gets converted to tri-iodothyronine called T3 which contains three atoms of iodine.

The pituitary gland is responsible for the regulation of the amount of T4 and T3 that is secreted by the thyroid gland. This gland lies underneath the brain, and it senses the number of thyroid hormones in your bloodstream. The pituitary gland is sensitive to little drops in the level of thyroid hormones in the blood, and it secretes the thyroid-stimulating hormone to activate the thyroid gland to secrete more of its hormones. The pituitary gland stops secreting this TSH when it senses that the amount of thyroid hormones in the blood is high. The name of this TSH is thyrotropin.

What Are Clinical Trials For Hyperthyroidism

How To Test For Thyroid Imbalance The Right Way

Clinical trialsand other types of clinical studiesare part of medical research and involve people like you. When you volunteer to take part in a clinical study, you help doctors and researchers learn more about disease and improve health care for people in the future.

Researchers are studying many aspects of hyperthyroidism, such as its natural history, clinical presentation, and genetics.

Don’t Miss: What Drugs Can Affect The Thyroid

Things That Can Affect Your Thyroid Function Results

Fasting Generally, you dont need to fast before doing a thyroid function test. However, not fasting is sometimes linked to a lower TSH level. This means your results might not pick up on mild hypothyroidism where your TSH levels are only mildly elevated.

Medications Some medications can interfere with your results so its important to tell your doctor about any drugs you take.

Pregnancy Being pregnant can also influence your results. So if youre pregnant make sure to discuss this with your doctor.

Whats Included In A Full Thyroid Panel

A full thyroid panel usually checks thyroid-stimulating hormone , triiodothyronine , and thyroxine levels. In some cases, a blood test for thyroid function will also check your bloodâs level of TPO antibodies. If you have abnormal thyroid hormone levels, high levels of TPO antibodies can point to an autoimmune thyroid disease as a possible reason for those abnormal levels.

Risk Factors For An Overactive Thyroid

  • A family history of Graves’ disease or autoimmune disorders
  • Women are more likely to develop hyperthyroidism compared to men
  • A personal medical history of specific chronic illnesses, including type 1 diabetes, pernicious anemia, or primary adrenal insufficiency
  • Common viral infections
  • Pregnancy
  • Age
  • Excess iodine intake

What Are Thyroid Nodules

The vital importance of thyroid health.

Thyroid nodules are small bumps that can form inside the thyroid gland. Approximately 90% of thyroid nodules are non-cancerous however, in some cases, these nodules may suggest the presence of thyroid cancer. Also, thyroid nodules can sometimes alter thyroid hormone levels, resulting in either hypothyroidism or hyperthyroidism.

Women are about 4 times more likely than men to have thyroid nodules. And older age, a history of thyroid radiation, and iron deficiency are all linked with a greater likelihood of having thyroid nodules.

Three Reasons Your Thyroid Test Came Back Negative

1. Normal is a Relative Term

Many screening thyroid tests will come back negative for thyroid disease if the patient falls in the normal TSH range, between 0.5 to 4.5. I consider anything above 2.5 to be diagnostic for hypothyroidism. You will also need a Free and total T4, Free and total T3 and Reverse T3 to make an accurate diagnosis. Do not rely on TSH alone! Be sure to also rule out any auto-immune component by checking for thyroid antibodies. About 60% of patients who have hypothyroidism have an auto-immune component.

2. Thyroid Levels Fluctuate Daily

Inaccurate thyroid testing is also caused by the fact that your thyroid hormones fluctuate on a daily basis. What you eat and what youre exposed to has an immediate impact on how much of the hormone your thyroid releases. Even the weather and seasonal changes can affect thyroid levels.

3. Conventional Tests Dont Measure Hormone Absorption

Your thyroid test may also have come back negative because although your hormone levels fall within the normal range, conventional thyroid tests do not measure how much of the hormone youre actually absorbing. If you have become resistant to the hormone due to an autoimmune reaction, you may not be able to utilize it no matter how much your thyroid gland is producing.

What Are The Symptoms Of Hyperthyroidism

High amounts of T4, T3, or both can cause an excessively high metabolic rate. This is called a hypermetabolic state. When in a hypermetabolic state, you may experience a rapid heart rate, elevated blood pressure, and hand tremors. You may also sweat a lot and develop a low tolerance for heat. Hyperthyroidism can cause more frequent bowel movements, weight loss, and, in women, irregular menstrual cycles.

Visibly, the thyroid gland itself can swell into a goiter, which can be either symmetrical or one-sided. Your eyes may also appear quite prominent, which is a sign of exophthalmos, a condition thats related to Graves disease.

Other symptoms of hyperthyroidism include:

Other tests may be performed to further evaluate your diagnosis. These include:

How To Test Your Thyroid Function

You can test your thyroid function using a blood sample. The two main ways to collect a blood sample are:

  • a venous blood test a trained professional will use a needle to puncture a vein, usually in your arm, to collect a blood sample.
  • a finger-prick blood test using a lancet, you can prick your own finger and collect a small blood sample.

Natural Remedies For Thyroid Issues

How to test your Thyroid at home

1. Ashwagandha

So for starters, the No. 1 natural remedy you need to start to support the thyroid is ashwagandha, which is proven to heal thyroid and adrenal issues. Ashwagandha is known as an adaptogenic herb. Adaptogen herbs mean they help you adapt and deal with stress, and ashwagandha has been used for thousands of years in Chinese medicine.

Other adaptogenic herbs can include things like tulsi or holy basil also things like rhodiola and ginseng and licorice root. All of those are adaptogen herbs, but ashwagandha may be the most effective at naturally supporting overall thyroid health, especially as a natural treatment for hypothyroidism and Hashimotos. In fact, in the studies on it, it was actually shown to help both hyper and hypothyroid symptoms, which is amazing.

So, you should definitely add ashwagandha to your hypothyroidism diet since it works as a way to treat hyperthyroidism and hypothyroidism.

2. Selenium

The No. 2 thing you should consider adding in to overall improve your thyroid function is selenium. The benefits of selenium are critical actually, selenium has very powerful antioxidant-like functions. In fact, studies have shown that selenium helps balance out T4 in your body hormones, so again, taking a therapeutic dose of selenium every day has also been shown to benefit thyroid function.

There are also foods high in selenium you can consume, including:

  • Brazil nuts

5. Proteolytic Enzymes

You’re Tired All The Time Or You Can’t Sleep

Insomnia can have many causes. But if you’re having a hard time sleeping, it could be hyperthyroidism, according to the Mayo Clinic. In addition, Dr. Block said, “I also find racing thoughts before bedtime often accompany hyperthyroidism.” That is something that we might think is psychological, but it can have a physical cause.

Another symptom to watch out for is fatigue, which can be a symptom of both hyperthyroidism and hypothyroidism. Dr. Ehsan Ali, the physician known as the Beverly Hills Concierge Doctor, told me that fatigue is a big sign you should get your thyroid checked.

Thyroid Function Blood Test

A GP may arrange for you to have a blood test to check your thyroid hormone levels. This is known as a thyroid function test.

The test checks the levels of:

  • thyroid-stimulating hormone a hormone produced by the pituitary gland which controls the production of thyroid hormones
  • triiodothyronine one of the main thyroid hormones
  • thyroxine another of the main thyroid hormones

Your thyroid hormone levels will be compared to what’s normal for a healthy person of your age. A low level of TSH and high levels of T3 and/or T4 usually means you have an overactive thyroid.

Doctors may refer to these measurements as “free” T3 and T4 .

What’s considered normal varies depending on things such as your age and the exact testing technique used by the laboratory.

What Are Thyroid Blood Tests And Why Are They Taken

Thyroid blood tests are used to tell if your thyroid gland is functioning properly by measuring the amount of thyroid hormones in your blood. They are done by withdrawing blood from a vein in your arm. These blood tests help to diagnose thyroid diseases.

The thyroid is a butterfly-shaped gland located in the front part of your neck. Its job is to produce thyroid hormones, which travel through your bloodstream and regulate many aspects of your bodys metabolism, including temperature, weight, and energy.

Thyroid blood tests show if you have:

  • Hyperthyroidism: Overactive thyroid producing more thyroid hormones than your body needs. Hyperthyroidism speeds up your metabolism, which can cause weight loss, rapid heartbeat, insomnia, puffiness around the eyes, anxiety and other symptoms. The most common cause of hyperthyroidism is Graves disease.
  • Hypothyroidism: Underactive thyroid producing too few thyroid hormones. Hypothyroidism slows down your metabolism, which can cause weight gain, menstrual irregularity, dry and puffy skin, fatigue and other symptoms. The most common cause of hypothyroidism is Hashimotos disease.

Thyroid blood tests are used to diagnose thyroid disorders associated with hyper- or hypothyroidism. These include:

Who Is At Risk For Hyperthyroidism

My Story

You are at higher risk for hyperthyroidism if you:

  • Are a woman
  • Are older than age 60
  • Have been pregnant or had a baby within the past 6 months
  • Have had thyroid surgery or a thyroid problem, such as goiter
  • Have a family history of thyroid disease
  • Have pernicious anemia, in which the body cannot make enough healthy red blood cells because it does not have enough vitamin B12
  • Have type 1 diabetes or primary adrenal insufficiency, a hormonal disorder
  • Get too much iodine, from eating large amounts of foods containing iodine or using iodine-containing medicines or supplements
