Restoring Thyroid Health: Part 1 — Hypothyroid

According to the American Thyroid Association (ATA), more than 12 percent of the U.S. population will develop a thyroid condition during their lifetime, an estimated 20 million Americans have some form of thyroid disease, and 60 percent of those with thyroid disease are unaware of their condition.

The ATA also points out that “undiagnosed thyroid disease may put patients at risk for certain serious conditions, such as cardiovascular diseases, osteoporosis, and infertility.”

The thyroid gland is a butterfly-shaped organ located just below the larynx (voice box). It is part of the endocrine system — the body’s chemical (hormone) messaging system.

Although it is relatively small, weighing only about 25 grams, its performance impacts every cell, tissue, and organ in the human body by regulating the body’s metabolism — the process by which the body extracts and uses energy from food.

In the endocrine system, the hypothalamus signals the pituitary gland whenever more thyroid hormone is needed. The pituitary gland then releases thyroid stimulating hormone (TSH) that tells the thyroid gland to produce the thyroid hormones Triiodothyronine (T3) and Thyroxine (T4).

This process regulates numerous vital bodily functions, including the following:

  • Breathing
  • Digestion
  • Heart rate
  • Mood and concentration
  • Strength and reflexes
  • Body temperature
  • Cholesterol levels
  • Menstrual cycles

Dysfunction of the thyroid gland can result in one of the following two conditions:

  • Hypothyroid: Underactive thyroid. The thyroid produces insufficient amounts of T3 or T4, which results in extreme fatigue, brain fog, weight gain, coarse hair and nails, hair loss, facial swelling, constant aches and pains, constipation, depression, poor sleep, and mood swings.
  • Hyperthyroid: Overactive thyroid. The thyroid produces excess amounts of T3 or T4, resulting in anxiety, rapid hair loss or alopecia, fine or oily hair and skin, rapid heart rate, hot flashes, inward trembling, weight loss, diarrhea, insomnia, and mood swings.

In this two-part series, we’ll discuss each of these conditions in turn and explain how we test for and treat each condition at the BioDesign Wellness Center in Tampa, Florida. In this first part, we focus on the diagnosis and treatment of hypothyroidism. In Part 2, we shift the focus to testing and treatment of hyperthyroid.

Understanding Hypothyroid

Think of the thyroid as the body’s master control. Every cell in the body requires thyroid hormone to perform its metabolic function. This is one reason why people gain weight with hypothyroidism, even with a reasonable diet and exercise.

It’s also why those with hypothyroidism can be so tired all the time — they often lack the motivation to move or to do anything at all. Clinical signs include elevated cholesterol, high triglycerides, insulin resistance, and anemia.

Unfortunately, in the conventional healthcare system, patients often suffer from hypothyroidism for quite some time, often many years, before the condition is diagnosed or treated.

During that time, patients are often subjected to less-than-effective treatments for the symptoms, including prescription and over-the-counter medications, as well as weight loss programs and fad diets.

For example, patients have often been prescribed antidepressants, weight-loss medications, cholesterol-lowering drugs, laxatives (for constipation), and various painkillers.

All along, treating the thyroid would have been more effective without exposing the patient to the negative side effects of those medications. Better yet, when the root causes of their hypothyroid are treated, people begin to feel much healthier and more vibrant.

Conventional Diagnosis and Treatment

The conventional diagnosis and treatment model for hypothyroid is to test the levels of T3 and T4 and then prescribe thyroid medication, such as levothyroxine or Synthroid, if necessary, to make up for any deficiencies.

These prescriptions can be helpful for some, but many people experience the same old symptoms soon after they start taking the medication or several years later.

In other words, you could be taking thyroid medication as prescribed by your internist or endocrinologist, and your TSH, T3, and T4 levels may appear normal. However, you may still feel miserable and continue to experience other symptoms of hypothyroidism.

And you would not be alone. We see many patients receiving conventional treatment who continue to experience symptoms of hypothyroidism.

The conventional approach to hypothyroid diagnoses and treats the cause of the symptoms but stops short of diagnosing and treating the cause of the hypothyroid.

Most hypothyroid problems can be traced back to an autoimmune disorder in which the immune system attacks the thyroid. This disorder is often referred to as Hashimoto’s thyroiditis.

People who suffer from Hashimoto’s thyroiditis typically experience alternating states of hypo and hyperthyroid (under and overactive thyroid). This condition is not life-threatening and does not require removal or radiation of the thyroid.

However, the person experiences a constellation of symptoms ranging from extreme anxiety to severe depression and from unexplained pain and fatigue to unexplained energy. In addition, patients who have Hashimoto’s thyroiditis are at an increased risk of developing other autoimmune disorders, including these:

  • Type 1 diabetes mellitus: The body produces little or no insulin or the insulin produced does not work as it should (insulin resistance).
  • Graves’ disease: The thyroid produces too much thyroid hormone (hyperthyroidism).
  • Rheumatoid arthritis: A chronic inflammatory condition affecting the joints, including those in the hands and feet.
  • Pernicious anemia: The inability to absorb vitamin B12, potentially causing anemia and neurologic problems.
  • Addison’s disease: Adrenal failure; the adrenal gland provides cortisol to handle stress and illness.
  • Premature ovarian failure: Early menopause.
  • Vitiligo: Patches where the skin loses its pigmentation.
  • Thrombocytopenic purpura: A bleeding disorder due to inadequate platelets in the blood.
  • Systemic lupus erythematosus (SLE): An autoimmune disease that can affect the skin, joints, heart, lungs, kidneys, and other organs.

Conventional doctors may adjust a patient’s thyroid medication dosage. Still, they rarely explore causes, offer dietary advice, or warn the patient of possible autoimmune triggers that should be avoided or corrected.

A Better Approach to Treating Hypothyroid

While conventional medicine approaches hypothyroid as the underlying cause of symptoms, a better approach is to view this condition as an effect of other underlying causes and then identify and treat those causes.

In the U.S., 80 to 90 percent of all cases of hypothyroidism are caused by autoimmune disorders. And the underlying causes of autoimmune disorders can be grouped into the following two categories:

  • Genetics: If your mother has or has had hypothyroidism, you have a 50 percent chance of developing it. It’s especially prevalent in women in their 50s and older.

  • Triggers: Triggers include stress, a physical trauma (such as a motor vehicle accident), infection, hormone fluctuations in pregnancy and menopause (and sometimes puberty), certain medications, toxic environments, chronic mold exposure, and pituitary gland dysfunction.

    A variety of infections can contribute to hypothyroidism, including Epstein-Barr virus (EBV), Lyme disease, or small intestinal bacterial overgrowth (SIBO).

While nothing can be done to address the genetic vulnerability, you can lessen the impact of the triggers and treat the underlying causes of the autoimmune disorder.

Doctors trained in Functional Medicine (like those here at BioDesign Wellness) often take a systematic approach to diagnosing and treating patients with suspected thyroid disorders.

We test first to identify underlying causes and then work on targeting those causes in treatment. In our practice, we take the following steps prior to recommending any treatment:

  1. Conduct a physical examination and carefully review the patient’s history. Thyroid dysfunction can be caused by physical trauma, certain medications a patient is taking or has taken in the past, exposure to environmental toxins, poor stress management, and so on. A physical exam and patient history often provide clues to what we need to test for.
  2. Order tests for the underlying cause(s) of thyroid dysfunctions, such as SIBO, EBV, Lyme disease, chronic mold exposure, and hormonal changes. These tests will vary considerably based on the initial evaluation.
  3. Order baseline testing on all thyroid markers, including antibodies. This testing reveals any dysfunction that may be causing the immune system to attack the thyroid.
  4. Perform a sonogram of the thyroid. A sonogram can help to identify whether the thyroid is inflamed, nodular, or has shrunk. We often diagnose Hashimoto’s thyroiditis through a combination of lab testing and sonogram on patients who had been living with hypothyroid for years and were unaware of it.
  5. Test for nutrient deficiencies that may be contributing to fatigue and low energy.

Depending on the patient and on the patient’s test results, treatment may include the following:

  • Review and adjust the diet to reduce inflammation in the gut, heal infections, reduce mold or yeast load, and balance blood sugar specific to the patient’s labs and clinical findings.
  • Restore a healthy balance of gut microbes and repair leaky gut / intestinal permeability.
  • Provide nutrient supplements to support proper thyroid function.
  • Use immune modulation supplements to calm the attack on the thyroid while monitoring thyroid antibodies and conducting sonogram studies.
  • Follow up with bi-weekly or monthly visits to ensure treatment is working and make any necessary adjustments as healthy thyroid function is restored.
  • Support with appropriate thyroid hormones. Some patients need T3 but are only taking T4. Many others need to adjust their dose of T4. Treating the underlying cause(s) may result in a need for less (or no) medication, so T3 and T4 supplementation must be carefully monitored and adjusted accordingly.

Starting with the Right Diagnosis

Proper treatment of hypothyroidism requires more than merely supplementing T4 and T3 when levels are low. An accurate diagnosis is necessary to determine why the thyroid is not producing/releasing sufficient thyroid hormones.

Then the treatment must address the underlying cause(s), whether it is Hashimoto’s thyroiditis, physical trauma, medications, pituitary dysfunction, or chronic inflammation.

Whether you see a conventional or functional medical doctor, keep in mind that diagnosis is the key to proper treatment. Make sure your doctor tests for thyroid antibodies to determine whether the cause of your hypothyroidism is an autoimmune disorder or something else. Until you know the cause, you are merely treating the symptoms.

The people we treat with symptoms of hypothyroidism see a vast improvement in their quality of life, including weight loss, increased energy, more restful sleep, less pain, and clearer thinking.
