What Is Iodine?

Iodine is a crucial mineral that your thyroid gland uses to produce thyroid hormones. Your thyroid hormones boost your metabolism, regulate your heartbeat, and control your digestive and muscular functions.

However, your body doesn’t naturally produce iodine. You can find this element in supplements and foods, such as:

  • Seafood, particularly shrimp, cod, and seaweed
  • Dairy products, like yogurt and milk
  • Eggs
  • Beef
  • Iodized salt

If you don’t have an adequate amount of iodine in your body, your thyroid gland won’t make sufficient hormones. This condition is called hypothyroidism.

What Are the Symptoms of Iodine Deficiency?

If your iodine’s low, you may experience uncomfortable or even severe symptoms. And since iodine deficiency and hypothyroidism are associated, their symptoms may be similar.

1. Weakness and Fatigue

Frailty and tiredness are low iodine symptoms.

Almost 80% of individuals with hypothyroidism feel worn out, inactive, and powerless.

For instance, if lifting heavy objects used to be an easy task, you may now find it difficult and stressful to do.

This occurs because your thyroid hormones help in energy production. They increase your metabolic rate. Therefore, when these hormone levels are low, you burn fewer calories.

Fewer calories may result in low energy. Limited energy levels mean less efficient muscles leave you feeling weak and exhausted.

2. Feeling Cold

Being more sensitive to low temperatures is a typical common iodine symptom.

Studies show that more than 80% of individuals with low levels of thyroid hormones may feel colder than usual.

Your thyroid hormones speed up your metabolism. So when your hormone levels are low, your metabolic rate may slow down. As your metabolism declines, your body produces less warmth causing you to feel cold.

Additionally, thyroid hormones regulate a particular type of fat, called brown adipose tissue or brown fat. Brown fat makes heat so your body can sustain cold conditions. Low thyroid hormones can prevent this fat from producing heat in your body.

3. Abnormal Menstruation

Is your menstrual flow heavier than usual? Is your menstrual cycle more than 38 days?

If so, these are low iodine symptoms.

According to a study, 68% of women with hypothyroidism experienced menstrual irregularities. Other research also reveals that women with low thyroid hormones have heavy periods. If you have hypothyroidism, there will be a disruption of hormones that regulate your period.

4. Goiter

If you’re deficient in iodine, your thyroid gland will expand as it tries to compensate for this deficiency. As a result, it’ll work harder to raise its production of hormones.

When this happens, your cells grow and multiply. Then, once your thyroid becomes swollen, it develops a visible lump in front of your neck, known as a goiter.

A goiter can make it hard for you to breathe and swallow. There’s even a possibility of choking.

Thankfully, increasing your iodine consumption can treat this condition. But if it’s left untreated for several years, it can result in permanent thyroid damage.

5. Hair Loss

It’s natural to shed around 50 to 100 hair strands per day. Your hair follicles replace these lost strands.

However, if you have low levels of iodine and thyroid hormones, your hair may stop growing. Thyroid hormones help in the renewal of your hair. They stimulate your follicles. Therefore, iodine deficiency may cause poor hair growth, eventually leading to hair loss.

6. Slow Heart Rate

Your heart rate, also called pulse, refers to how fast your heart contracts or beats per minute. And your iodine levels can affect the speed of your heartbeat.

If you have iodine deficiency, your heart tends to contract slower than usual. Slow heart contraction can leave you feeling lightheaded, tired, and sick. It can even possibly cause you to pass out.

7. Unintentional Weight Gain

Unexpectedly putting on weight is a symptom of low iodine.

As we mentioned earlier, thyroid hormones increase metabolic processes.

Normal levels of iodine and thyroid hormones mean healthy metabolism. On the other hand, low levels of these minerals and hormones entail slow metabolism.

When your metabolism slows down, you burn fewer calories. Additionally, your body stores the calories you consume as fat resulting in more pounds on the weighing scale.

However, keep in mind that there are still other causes of weight gain, such as eating more calories and a sedentary lifestyle.

8. Dry Skin

If you have low iodine, you may experience scaling or peeling skin.

Thyroid and iodine-containing hormones help heal and regenerate skin cells. So when these hormones are low, skin repair and rejuvenation don’t occur as often. Dead skin cells may build up. As a result, your skin becomes dry and flaky.

Furthermore, thyroid hormones help regulate your sweat glands. When these hormones are low, your sweating reduces. And since sweat hydrates and moisturizes your skin, a lack of it may also lead to dry skin.

9. Pregnancy Complications

Iodine is vital for a baby’s brain and bone development. Because pregnant women support the iodine requirement for your body and the growing baby inside them, they are at a high risk of developing iodine deficiency.

If you’re having problems with your pregnancy, it may mean that you’re low in iodine. And extreme iodine deficiency may lead to:

  • Preterm birth
  • Miscarriage
  • Stillbirth

It’s also important to note that having iodine deficiency while pregnant may cause problems for your baby as well, such as:

  • Walking abnormality
  • Deaf-mutism
  • Mental retardation
  • Growth disorders

10. Cognitive Impairment

A symptom of low iodine is having a hard time learning and remembering. Because iodine affects your brain function and development, Iodine deficiency may cause mental development disorders.

Based on a study, individuals with low thyroid hormone levels have a smaller hippocampus, a part of the brain involved in learning and memory.
