Iodine

What Are The Signs & Symptoms of Iodine Deficiency?

Why does the body need Iodine?

Iodine is a water soluble mineral that is needed in our diet to ensure that the thyroid works properly.The thyroid gland uses iodine to make thyroid hormones.

Thyroid hormones play an important role in a wide range of bodily functions, including metabolism, bone growth, immune response, and development of brain and the central nervous system (CNS).

Iodine helps convert thyroid stimulating hormone (TSH) to triiodothyronine (T3) and thyroxine (T4). This conversion is important for the thyroid to function properly.

Iodine is essential for brain development, bone health, healing, immune response, energy, metabolism and the development of the central nervous system. We also now know that we need iodine to help with pregnancy and fertility. Iodine deficiency during pregnancy and early childhood can also lead to developmental problems.

An iodine imbalance can lead to an overactive, or under-active thyroid.

Being deficient in iodine limits the ability of the thyroid gland to make hormones, causing hypothyroidism. Hypothyroidism happens when a person’s thyroid does not produce enough thyroid hormones. Hypothyroidism can cause symptoms of fatigue, depression, forgetfulness, hair weakness, hair loss, dry skin, weight gain, cold intolerance and constipation.

Signs of iodine deficiency

According to new research published last year, it was estimated that about a third of people are deficient in iodine. Here are some of the common signs that could suggest that a person may have an iodine deficiency.

1.Weight gain

One of the most noticeable signs of an iodine deficiency is unexpected weight gain.

When a person has a healthy metabolism, they burn calories to give them their energy. Hypothyroidism, or a lack of thyroid hormones, can slow down a person’s metabolism and this can then lead to weight gain. It is important to remember that weight gain is not always a sign of an iodine deficiency. It may only be a symptom when weight gain cannot otherwise be explained. Eating foods that are highly refined and high in sugars are probably the most common form of increase weight.

2.Feeling weak & lethargic

When a person has an iodine deficiency, they may feel weak and lethargic. Hypothyroidism can slow down a person’s metabolic rate and then they burn fewer calories for energy. When they have less energy, the muscles do not work as efficiently and then the person would feel weak. But, feeling weak may also be from other factors such as lack of sleep, lack of essential nutrients, lack of food intake and nutrient deficiencies. This may also be a sign of other health issues and needs to be investigated if it goes on too long.

3.Feeling tired

Unexplained tiredness may be a symptom of iodine deficiency. When a person is iodine deficient their metabolic rate may drop and this could cause them to feel tired. But, feeling tired does not always mean a person is iodine deficient. As mentioned before, if a person is not getting enough rest, it is natural for them to feel tired. Feeling tried could also be a sign of iron deficiency, or other health issues, but, if tiredness is unexplained, it may be a symptom of an iodine deficiency.

4.Hair Loss

Hair loss is another possible sign that a person might have an iodine deficiency.

Thyroid hormones support the renewal of hair follicles and when someone has hypothyroidism, a shortage of thyroid hormones means the hair follicles stop being renewed. It is natural for hair to fall out, but it is normally renewed. But, while hair loss can be a sign of iodine deficiency, it can also be caused by other hormonal issues as well as stress. Stress is one of the most common causes of hair loss.

5.Drying skin

Having dry, flaky skin could be a sign of hypothyroidism, and can be the result of iodine deficiency. Thyroid hormones help with the renewal of new skin cells. A lack of these hormones and a deficiency of iodine, may cause dead skin cells to build up, sometimes resulting in dry, flaky skin. While dry skin can be caused by iodine deficiency, it can also be caused from other factors such as lack of hydration, lack of essential oils and other health conditions

6.Feeling cold

Iodine deficiency causes a lack of thyroid hormones, which can then affect a person’s metabolic rate to slow down. As their metabolism slows down, a person produces less energy to give the body warmth. A lack of energy and lack of body heat will mean a person is more likely to feel the cold. But, feeling cold isn’t always a sign of iodine deficiency and can be a sign of lack of circulation and other health issues.

7.Having a slow heart rate

Having an iodine deficiency may make a person’s heart beat more slowly.

When a person’s heart rate slows down, they may feel a bit dizzy, nauseas, or sick. It may also make them feel a bit faint. But feeling this way may also be a sign of other health issues, or it could also be a sign of a virus, or issue with someone’s cardiovascular system and needs to be checked out.

8.Learning or memory problems

Thyroid hormones are important for brain development and Iodine deficiency may cause a lack of these hormones, resulting in problems with memory and learning. Studies have shown that people, who are deficient in iodine and have lower level of thyroid hormone, may have parts of their brain being smaller and this then affects their memory. But while this may be the case, learning and memory problems could be caused from other health issues and need to be checked out properly

9.Pregnancy complications

Iodine deficiency may cause issues during pregnancy for the developing baby and it can be harder to get enough iodine during pregnancy. Not only does a women need iodine for herself, but she needs it for the growing baby inside of her as well.

Thyroid hormones are necessary for the healthy development of a baby before it is born. A lack of iodine and thyroid hormones may prevent the baby’s brain developing properly. It may also affect their immune system and affect their growth. If a pregnant woman’s body is too low in iodine it could cause her baby to be stillborn.

10.Heavy or irregular periods

Deficiency in iodine can lead to low thyroid hormone levels, which can then affect the levels of hormones that regulate a woman’s periods. Iodine deficiency can lead to periods that are heavier than usual, or the periods that are more or less often than usual. While, iodine deficient could cause abnormal abnormalities in a woman’s menstrual cycle, irregular or heavy periods are usually a sign of gynaecological conditions that needs to be evaluated by a specialist.

11.Swollen neck and goitres

If a person is deficient in iodine, the thyroid gland can become enlarged and this can then make the neck become swollen. This can lead to a condition called goitre. Abnormalities with the thyroid gland and hormones can also cause growths called nodules.

When the thyroid does not have enough iodine, it will try to absorb more from the blood and this then causes the thyroid to become enlarged, making the neck appear swollen.

Complications and diagnosis.

An iodine deficiency may happen when a person does not consume enough foods that are rich in iodine, or have adequate supplementation. This deficiency is more likely to affect pregnant women who need a higher intake of iodine.

Pregnant women and their babies experience the most serious complications of iodine deficiency. In the worst cases, it can lead to babies being stillborn or born with mental issues due to stunted brain development.

If you think you may be deficient in iodine you can go to your doctor and they can organise proper testing for you. The most effective way to diagnose iodine deficiency is via a urine test.

If you have a family history of thyroid issue, or are to conceive, or are pregnant, you should be supplementing with iodine based multivitamins or individual supplements. A person needs to consume 150 micrograms (mcg) of iodine each day to maintain a healthy level for their body. You should also be looking at eating iodine rich foods daily as well.

The following are good sources of iodine:

  • Seaweed
  • Cod, tuna, salmon and white fish
  • Plain Yogurt, Cheese and Milk
  • Iodized salt
  • Shell fish and oysters
  • Eggs
  • Dried prunes

Thyroid

Could your health issues be coming from your Thyroid?

Thyroid issues are common, especially in women and especially if there is a family history of thyroid disorders in your family. When your thyroid goes out of balance, it can cause all sorts of symptoms and issues in your body. You need to know what to look for.

When Your Thyroid Goes Awry

Does fatigue drag you down day after day?

Do you have brain fog, weight gain, chills, or hair loss?

Or is the opposite true for you: Are you often revved up, sweaty, or anxious?

Your thyroid gland could be to blame. This great regulator of body and mind sometimes goes haywire, particularly in women. Pregnancy and postpartum is when it can also go haywire too. Getting the right treatment is critical to feel your best and avoid serious health problems.

What Is the Thyroid Gland?

The thyroid is a butterfly-shaped gland in the front of the neck. It produces hormones that control the speed of your metabolism — the system that helps the body use energy. Thyroid disorders can slow down or rev up metabolism by disrupting the production of thyroid hormones. When hormone levels become too low or too high, you may experience a wide range of symptoms.

Symptom: Weight Gain or Loss

An unexplained change in weight is one of the most common signs of a thyroid disorder. Weight gain may signal low levels of thyroid hormones, a condition called hypothyroidism. In contrast, if the thyroid produces more hormones than the body needs, you may lose weight unexpectedly. This is known as hyperthyroidism. Hypothyroidism is far more common.

Symptom: Swelling in the Neck

A swelling or enlargement in the neck is a visible clue that something may be wrong with the thyroid. A goiter may occur with either hypothyroidism or hyperthyroidism. Sometimes swelling in the neck can result from thyroid cancer or nodules, lumps that grow inside the thyroid. It can also be due to a cause unrelated to the thyroid.

Symptom: Changes in Heart Rate

Thyroid hormones affect nearly every organ in the body and can influence how quickly the heart beats. People with hypothyroidism may notice their heart rate is slower than usual. Hyperthyroidism may cause the heart to speed up. It can also trigger increased blood pressure and the sensation of a pounding heart, or other types of heart palpitations.

Symptom: Changes in Energy or Mood

Thyroid disorders can have a noticeable impact on your energy level and mood. Hypothyroidism tends to make people feel tired, sluggish, and depressed. Hyperthyroidism can cause anxiety, problems sleeping, restlessness, and irritability.

Symptom: Hair Loss

Hair loss is another sign that thyroid hormones may be out of balance. Both hypothyroidism and hyperthyroidism can cause hair to fall out. In most cases, the hair will grow back once the thyroid disorder is treated.

Symptom: Feeling Too Cold or Hot

Thyroid disorders can disrupt the ability to regulate body temperature. People with hypothyroidism may feel cold more often than usual. Hyperthyroidism tends to have the opposite effect, causing excessive sweating and an aversion to heat.

Other Symptoms of Hypothyroidism

Hypothyroidism can cause many other symptoms, including:

  • Dry skin and brittle nails
  • Numbness or tingling in the hands
  • Constipation
  • Abnormal menstrual periods

Other Symptoms of Hyperthyroidism

Hyperthyroidism can also cause additional symptoms, such as:

  • Muscle weakness or trembling hands
  • Vision problems
  • Diarrhea
  • Irregular menstrual periods

Thyroid Disorder or Menopause?

Because thyroid disorders can cause changes in menstrual cycle and mood, the symptoms are sometimes mistaken for menopause. If a thyroid problem is suspected, a simple blood test can determine whether the true culprit is menopause or a thyroid disorder — or a combination of the two.

Who Should Be Tested?

If you think you have symptoms of a thyroid problem, ask your doctor if you should be tested. People with symptoms or risk factors may need tests more often. Hypothyroidism more frequently affects women over age 60. Hyperthyroidism is also more common in women. A family history raises your risk of either disorder.

Thyroid Neck Check

A careful look in the mirror may help you spot an enlarged thyroid that needs a doctor’s attention. Tip your head back, take a drink of water, and as you swallow, examine your neck below the Adam’s apple and above the collarbone. Look for bulges or protrusions, then repeat the process a few times. See a doctor promptly if you see a bulge or lump.

Diagnosing Thyroid Disorders

If your doctor suspects a thyroid disorder, a blood test can help provide an answer. This test measures the level of thyroid stimulating hormone (TSH), a kind of master hormone that regulates the work of the thyroid gland. If TSH is high, it typically means that your thyroid function is too low (hypothyroid). If TSH is low, then it generally means the thyroid is overactive (hyperthyroid.) But just measuring TSH levels is not enough. People with thyroid disorders can have normal TSH levels and the other thyroid hormone levels and this is why thyroid antibody testing is probably the most important testing to be done. High thyroid antibodies mean you have a thyroid condition and your thyroid gland is under attack. Hopefully doctor will want to check all the other thyroid hormones in your blood. If he/she doesn’t, make sure they do. They should always check TSH, Free T3, Free T4, Reverse T3 and Thyroid antibodies. In some cases, imaging studies are used and biopsies are taken to evaluate a thyroid abnormality.

Hashimoto’s Disease

The most common cause of hypothyroidism is Hashimoto’s disease. This is an autoimmune disorder in which the body attacks the thyroid gland. The result is damage to the thyroid, preventing it from producing enough hormones. Hashimoto’s disease tends to run in families. This is why thyroid antibodies needs to be checked because people with Hashimotos disease can actually have normal TSH levels and normal Free T3, Free T4 and reverse T3 levels.

Other Causes of Hypothyroidism

In some cases, hypothyroidism results from a problem with the pituitary gland, which is at the base of the brain. This gland produces thyroid-stimulating hormone (TSH), which tells the thyroid to do its job. If your pituitary gland does not produce enough TSH, levels of thyroid hormones will fall. Other causes of hypothyroidism include temporary inflammation of the thyroid or medications that affect thyroid function.

Graves’ Disease

The most common cause of hyperthyroidism is Graves’ disease. This is an autoimmune disorder that attacks the thyroid gland and triggers the release of high levels of thyroid hormones. One of the hallmarks of Graves’ disease is a visible and uncomfortable swelling behind the eyes. Again this is why testing thyroid antibodies is so important.

Other Causes of Hyperthyroidism

Hyperthyroidism can also result from thyroid nodules. These are lumps that develop inside the thyroid and sometimes begin producing thyroid hormones. Large lumps may create a noticeable goiter. Smaller lumps can be detected with ultrasound. A thyroid uptake and scan can tell if the lump is producing too much thyroid hormone.

Thyroid Disorder Complications

When left untreated, hypothyroidism can raise cholesterol levels and make you more likely to have a stroke or heart attack. In severe cases, very low levels of thyroid hormones can trigger a loss of consciousness and life-threatening drop in body temperature. Untreated hyperthyroidism can cause serious heart problems and brittle bones.

Treating Hypothyroidism

If you are diagnosed with hypothyroidism, your doctor will most likely prescribe thyroid hormones in the form of a pill. This usually leads to noticeable improvements within a couple of weeks. Long-term treatment can result in more energy, lower cholesterol levels, and gradual weight loss. Most people with hypothyroidism will need to take thyroid hormones for the rest of their lives.

Treating Hyperthyroidism

The most common treatment for hyperthyroidism is antithyroid medication, which aims to lower the amount of hormones produced by the thyroid. The condition may eventually go away, but many people need to remain on medication for the long term. Other drugs may be given to reduce symptoms such as rapid pulse and tremors. Another option is radioactive iodine, which destroys the thyroid gland over the course of 6 to 18 weeks. Once the gland is destroyed, or removed by surgery, most patients must begin taking thyroid hormones in pill form.

Surgery for Thyroid Disorders

Removing the thyroid gland can cure hyperthyroidism, but the procedure is only recommended if antithyroid drugs don’t work, or if there is a large goiter. Surgery may also be recommended for patients with thyroid nodules. Once the thyroid is removed, most patients require daily supplements of thyroid hormones to avoid developing hypothyroidism.

What About Thyroid Cancer?

Thyroid cancer is uncommon and is among the least deadly. The good thing with thyroid cancer is that it is encapsulated, so it won’t spread. Once the thyroid gland is removed, the cancer is removed also. The main symptom is a lump or swelling in the neck, and only about 5% of thyroid nodules turn out to be cancerous. When thyroid cancer is diagnosed, it is most often treated with surgery followed by radioactive iodine therapy or, in some cases, external radiation therapy

Complementary Medicine For Thyroid Issues

There are complementary medicines that may assist thyroid issues and it is important that you have a consultation and talk to a qualified healthcare practitioner about these options.

There are also supplements and other herbal medicine that may assist thyroid function, or balancing the thyroid hormones.

Diet and lifestyle changes are also very important for thyroid health, as is working on the gut and microbiome to reduce inflammation in the body and assist the immune system as well. There are also compounded natural thyroid medications that may assist thyroid issues as well.

Please make sure you see your healthcare practitioner, or endocrinologist for help with thyroid issues and ongoing management and never try to manage things on your own.

If you need assistance with thyroid management and management of other hormonal issues, please call my friendly clinic staff and they will be able to book you in for a consultation and explain more.
