The Most Common Thyroid Disorders and What You Need to Know

The thyroid is a small butterfly-shaped gland which plays an important role in your well-being and health. So how come we know so little about it?

Your thyroid lies in the front of your neck, just below ‘Adam’s apple’ (this is the lump or protrusion that is formed by the angle of the thyroid cartilage surrounding the larynx which is also called the ‘voice box’). The thyroid makes the hormones to makes sure the body’s metabolism, temperature, vitality and development are in order. Women are affected by thyroid disorders more often than men, and some statistics show that 1 in 8 women will suffer from a problem related to this endocrine gland at some point in their life.


Scientists now believe that thyroid disorders are often caused by the person’s lifestyle; it’s not all down to genetics. The main external factors include exposure to a toxic environment, the consumption of chemically­-laden food and water, and deficiency of certain nutrients.

In this article, I’ll briefly introduce the thyroid’s function, and describe the five most common thyroid disorders, as well as treatments for them.

Functions of the Thyroid

The thyroid gland takes iodine from the food and converts it into thyroid hormones (T3 and T4). Hence, in geographic areas where iodine supply is scarce (and is not supplemented), we can often see more people with thyroid problems. Iodized table salt is usually a good source of iodine.

The brain’s pituitary gland controls the activity of your thyroid gland by secreting TSH (thyroid stimulating hormone). This is the hormone that stimulates the thyroid to produce thyroid hormones T4 (thyroxine) and T3 (triiodothyronine).

T3 and T4 are two of the hormones the thyroid secretes and they control the metabolism. The other thyroid hormone is calcitonin, which regulates calcium levels in the blood and bones.

The thyroid makes sure we have sufficient energy – the first symptom telling you that something is wrong is often tiredness. The thyroid is responsible for growth and development. If children don’t get enough thyroid hormones when they’re growing up, this can result in brain abnormalities and lower IQ.

Normally, the thyroid is not visible or palpable. When the function is disturbed, the gland can become abnormally enlarged – this is known as goiter.

In general there are 13 signs you may have a thyroid disorder and you can find below 5 specific thyroid disorders with their symptoms and specific treatments.


This condition is characterized by an overactive thyroid that produces too much T3 and T4 hormones. Symptoms of hyperthyroidism include:

  • Low TSH levels
  • Unexplained weight loss
  • Mood changes: feeling moody, anxious, nervous
  • Goiter (when Graves’ disease is the underlying cause)
  • Tiredness
  • Excessive sweating
  • Diarrhea
  • Loss of hair
  • Muscle weakness
  • Heart palpitations and problems breathing
  • In some cases, calcium deposits on face
  • Irregular periods

The condition is easily treatable. However, if it remains untreated, serious heart problems can develop.

Conventional treatments for hyperthyroidism: If the condition is in its mild form, anti-thyroid drugs are prescribed. If hyperthyroidism is a result of Graves’ disease (which will be described later) or you are over 50, radioactive iodine is commonly used. In some cases, surgery is recommended, especially if the enlarged thyroid obstructs breathing.

Natural treatments for hyperthyroidism: Natural treatments are mainly based on diet changes and some of the steps you need to take to normalize the function of this gland include:

  • Limiting foods that contain goitrogens (or preparing these foods in a different way) – goitrogens are compounds that make it more difficult for the thyroid to perform its function; examples of such foods include soy, peanuts, strawberries, broccoli and kale.
  • Filtering water to eliminate fluoride, bromine and chlorine.
  • Avoiding gluten.
  • Introducing supplements: lithium orotate, probiotics, vitamin D3, omega­-3 fats.

Certain lifestyle changes will also support the treatment process. Make sure you get enough sleep, reduce your stress levels, and avoid caffeine and smoking.


Doctors diagnose hyperthyroidism by testing if TSH levels are normal, high or low and in combination with T3 and T4 levels.


This is a condition opposite to the one described above – the thyroid gland is underactive and doesn’t produce enough of its hormones. A person can already be born with a gland deficiency, or the condition can develop later due to autoimmune causes (such as Hashimoto’s thyroiditis described below), radiation therapy and certain medications, or too little iodine in the diet.

The main symptoms include:

  • High TSH levels
  • Unexplained weight gain
  • Constipation
  • Depression
  • Fatigue
  • Pale dry skin
  • Baldness
  • Increased sensitivity to cold
  • Goiter (if the underlying cause is Hashimoto’s thyroiditis)

Conventional treatments for hypothyroidism: A synthetic thyroid hormone is used to increase your T3/T4 hormone levels. The pill needs to be taken every day.

Natural treatments for hypothyroidism: I’ve discussed the natural treatments in my article about the 8 natural remedies for hypothyroidism.


Hashimoto’s Thyroiditis (Hashimoto’s Disease)

Hashimoto’s thyroiditis is an autoimmune condition, which means that the body starts attacking its own cells. It is the most common cause of hypothyroidism. Experts believe that the disease initially develops as a result of a virus, bacteria or a foreign body. Not eating enough iodine and exposure to chlorine/fluoride/bromine can also play a role.

The symptoms are similar to hypothyroidism. Hashimoto’s is also characterized by goiter – enlarged thyroid.

Graves’ Disease

Graves’ disease, too, is an autoimmune disorder and causes thyroid hormone overproduction (hyperthyroidism). The causes are very similar to Hashimoto’s disease, and the resulting symptoms are those of hyperthyroidism.

This is the swelling or inflammation of the thyroid gland, and can present either as hyperthyroidism or hypothyroidism. Hashimoto’s is one type of thyroiditis. The other common type, which occurs in 5 to 10 percent of women after they’ve given birth, is called postpartum thyroiditis. It has two phases:

  • The first phase starts 1 to 4 months after giving birth and results in hyperthyroidism. The damaged thyroid is leaking hormones into the blood.
  • The second phase occurs 4 to 8 months post-pregnancy and presents as hypothyroidism, as by then, the thyroid has lost most of its hormones.

In most women, postpartum thyroiditis resolves by itself within 12 to 18 months post delivery. Treatment can be given and it depends on whether the symptoms are those of hyper- or hypothyroidism.

Other types of tyroiditis include silent or painless thyroiditis and subacute thyroiditis. They both have similar presentation to postpartum thyroiditis, but are not connected with giving birth.

    I have a lingual thyroid, it’s rare and I was born with it. It is located on the base of my tongue and visible if I say “ahhhh”. I really want to look into having it removed due to trouble swallowing, uncomfortableness and other issues. I am having a very difficult time finding a doctor even remotely familiar with this thyroid condition however …

      I think you might be interested to read my article about Top 13 Signs That You May Have a Thyroid Disorder which talks more about hypo vs. hyper. For an accurate diagnosis you will need to refer to your doctor (as I’m not a doctor).

    • Julie Scott says:

      Hi I have the exact same as you. However with the hair loss and breathing difficulties I have put weight on not lost it! Did you manage to sort out your real problem of either hyper or hypo?


    • Regina says:

      I had HYPO signs ..Thought FORSURE after Gram,Mom, and Twin Sister are all HYPO…Turned Out GRAVES..I believe Since Puberty, but forsure likely started at 20 after 1st birth of 4 last One at 36 Graves at 43

    My daughter has Hashimoto’s and takes synthroid, so I know that she has to be careful about what supplements she takes.
    I am an herbalist and would like a resource to look up what herbs or plants would be beneficial or contraindicated for her. For example, I think she would greatly benefit from Pomegranate Leaf tincture or tea, but how can I know if it’s compatible with her Synthroid?
    What resource would you recommend for me to find this kind of information? Her doctor or pharmacist do not understand plant medicine.
