Thyroid Issues in Reno

An estimated 12 percent of the U.S. population will develop a thyroid condition or problem during their lifetime. 60 percent of those patients are symptomatic but unaware of their condition. ⁽¹⁾

The thyroid gland, a butterfly shaped organ, is located in the laryngeal prominence, i.e. the Adam’s apple, in the neck.  It’s hormones, chemicals, that carry messages from their organ of origin to specific cells, regulates the function of every cell in the body. The thyroid is responsible for the smooth functioning of the heart, lungs, G.I. tract, blood sugar, cholesterol production and utilization, bone, blood, and brain.

The thyroid gland produces two major hormones, triiodothyronine (T3) and thyroxine (T4). T3 and T4 are major regulators of the growth and rate of function of other body systems. The thyroid also produces calcitonin, a hormone responsible for calcium balance and bone density.

The thyroid is a “Goldilocks” hormone. We need it to be just right, not too little, not too much. It produces itself only 20% of its’ necessary daily requirements (100 micrograms a day of T4, 30 micrograms a day of T3). The majority (80%) of the active thyroid molecule comes from a process known as deionization, naturally converting T4 to T3. Adequate conversion of T4 to T3 accounts for a smooth running system. Inadequate conversion of T4 to T3 contributes to the symptoms of low circulating thyroid which in turn causes many thyroid issues in Reno.

The thyroid is such a ubiquitous organ that over 200 different symptoms can be traced to it. Common symptoms include cold intolerance, unexplained weight gain, fatigue, thinning of the hair, the outer third of the eyebrow, the skin and the nails, increased body fat, energy loss, cognitive loss, memory loss, mood disorders, lowered body temperature (never greater than 97.6 F), fluid retention, and a poor sense of well-being are all attributable to poor thyroid function.

Although thyroid deficiency has traditionally been viewed as a decrease in hormone production from the aforementioned decreased conversion of T4 to T3, zinc and selenium deficiencies, adrenal insufficiency, thyroid receptor site resistance (normal blood levels, poor thyroid function), and pharmaceutical medications including amiodarone, beta blockers, dilantin, prednisone, synthetic progesterones, and lithium, a new understanding has arisen.

When the underlying cause of hypothyroidism is the immune system, not the thyroid per se., and it is not addressed, the treatment will not be effective. ⁽²⁾

25 percent of patients with Hashimoto’s thyroiditis develop polyglandular syndromes (such as pernicious anemia, diabetes, or adrenal insufficiency) or other autoimmune diseases (such as Sjogren’s syndrome). ⁽³⁾

Diagnosing thyroid deficiency is a hot topic. Battle lines were drawn several years ago when patients, obviously hypothyroid, were told they were “normal” because a single test, the TSH, was inside a “normal” 2 standard deviations or 95% of a cross section healthy adults range.

“The serum thyrotropin (TSH) is the single best screening test for primary thyroid dysfunction for the vast majority of outpatient clinical situations. The standard treatment is replacement with levothyroxine. The decision to treat sub clinical hypothyroidism when the serum thyrotropin is less than 10 mIU/L should be tailored to the individual patient.” ⁽⁴⁾

 o10!  Even the most generous standard lab has an upper reference range of 4.5 mIU/L.

This reference range, one size fits all, cookbook medicine approach, leaves millions of clearly hypothyroid patients, un and under diagnosed and un and under treated. Left alone, hypothyroidism can progress to enlarged hearts, heart failure, brain fog, infertility and miscarriage.

The risk of elevated blood pressure, Hashimoto’s Disease, and depression in relation to the thyroid can be seen with a TSH reading as low as 1.9. At 2.0, elevated markers for cardiac and carotid (c Reactive Protein and Homocysteine) disease are evident. When the TSH is 3.3 or greater severe forms of depression, increased body mass index, and blood sugar abnormalities are common. ⁽⁵⁾ These are all within the confines of a “normal” thyroid!

The sweet spot, the place where our patients function at their very best, are happiest, and have the best cognitive function, best lipid profiles, no cardiac irregularities, or bone loss is really 0.1 and 1.0 mIU/L. ⁽⁶⁾

Thyroid hormones once released, travel in the blood stream either bound to a protein or in free form. T3 is the functioning thyroid molecule. Only the free form is available to produce the desired hormonal effect. Knowing the amount of circulating thyroid hormone available, the free T3, and supporting it to an optimal state, further enables us to refine our patients’ health.

While nice to know, free T4 reflects the biologically active hormone that converts to T3 or reverse T3, an inert form of T3, that also masks hypothyroidism. It is the free T3 that we must pay attention too.

Free T3 is the active hormone that generates cellular energy. Optimizing free T3 within its’ optimal range (3.8-4.2), along with TSH (0.5-2.0) and the patient’s symptoms provide the basis for a treatment plan.

Reverse T3 (rT3) reflects the level of a second T3 molecule that is formed from T4 conversion. rT3 is an inert form of T3 that will mask an inactive, yet sometimes adequate free T3 level. It is as if the conversion was led astray, into a blind alley. It’s there, but unless you look for it, reverse T3 will be missed. We calculated a free T3/rT3 ratio looking for a value greater than or equal to 20, This free T3/rT3 ratio is the most useful marker for tissue hypothyroidism and as a marker of diminished cellular functioning. ⁽⁷⁾

Symptoms of an elevated reverse T3 include fatigue, difficulty losing fat, brain fog, and muscle aches.

Elevated reverse T3 results from chronic illnesses, yo-yo dieting, heavy metal exposure, infections, and mental and physical stress.

Autoimmune disruptions of the thyroid gland include Hashimoto’s Thyroiditis (hypothyroidism) and Grave’s Disease (hyperthyroidism).

In Hashimoto’s Thyroiditis, anti-thyroglobulin antibodies are elevated in 70% and thyroid peroxidase (TPO) antibodies are elevated in greater than 90 % of presenting cases. Hashimoto’s patients are profoundly hypothyroid and merely replacing the thyroid deficit is usually not adequate for optimal health.  In the presence of extremely high levels of thyroid peroxidase antibodies (>120), Hashimoto’s Thyroiditis can be present without overt hypothyroid symptomatology. Chronic fatigue, dry hair, chronic irritability and nervousness, a history of breast cancer and early miscarriage are its’ hallmarks (8)

At the other end of the spectrum, Graves Disease is the autoimmune equivalent of hyperthyroidism. Thyroid Stimulating Immunoglobulin (TSI) is the measure for a definitive diagnosis.

Remedies for thyroid disease are as controversial as the diagnosis. The American Association of Clinical Endocrinologists and the American Thyroid Association emphatically declared, in 2012, “the standard treatment is replacement with Levothyroxine.” ⁽⁹⁾

On the surface this seems to make sense. Nearly 80% of circulating thyroid is T4. T4 naturally converts to T3 so why bother with a more complicated compound? The problem is L-thyroxine, T4 only products, including Synthroid, levothyroxine, levoxyl to name a few, in many cases fail to convert its’ substrate to T3.

Failure to adequately convert T4 to T3 not only results in clinical hypothyroidism, but adrenal fatigue or “burnout” also. Low thyroid output creates a stressful internal environment requiring increasing levels of Cortisol. Chronically high Cortisol levels result in inflammation and accelerated cardiovascular and heart disease.

Other causes of T4 to T3 conversion failure include dieting, renal or hepatic disorders, cancer, trauma, insulin resistance, and growth hormone deficiency. Medications that interfere with conversion include glucocorticoids, amiodarone, beta blockers, synthetic progesterone (Provera), selenium and zinc deficiencies.

Adding T3 to the regimen in a ratio of approximately 4 parts T4 to 1 part T3 as this is how nature produces thyroid. T3 is needed for fat loss, protects against arrhythmias, decreases with stress or dieting, and is the active hormone actually performing the work of the thyroid.

We prefer to treat our patients with desiccated thyroid, T3/T4 in the exact ratio as is found in nature.

Non-pharmacologic remedies include ensuring patients have an adequate supply of selenium, iodine, zinc, Vitamin D, and glutathione.

There is a strong link between gluten sensitivity and intolerance and thyroid disease. ⁽¹⁰⁾ We strongly recommend all our autoimmune and non-autoimmune patients to be screened for gluten antibodies.

Gliadin, the protein portion of gluten is chemically similar to thyroid hormones. This protein, if it enters the bloodstream as it does in celiac disease, triggers an autoimmune response in the G.I. tract and in a case of mistaken identity, the thyroid.

We recommend our thyroid patients try a gluten free diet for at least 30 days. While this again is controversial, the New York Times, panned this approach in an article written on July 5, 2015, it has been quite a game changer for thousands of patients and best of all, it costs nothing!

Cruciferous vegetables, including broccoli, cabbage, Brussels sprouts, kale, and soy among others are goitrogens, that is they increase the need for iodine in small amounts.   In large amounts they can damage the thyroid. Steaming can reduce the danger by ⅓ and thoroughly cooking them and discarding the water in case of boiling decreases the harm by 90%.

Avoid very low carb or zero carb diets. They tend to inhibit conversion of T4 into T3. We recommend the GAPS Diet, ⁽¹¹⁾ the Metabolic Code Diet, (12) a gluten free diet, or our Thyroid Reset Diet.

General food considerations include sea vegetables, kelp flakes, wakame, arame, and hijiki. Fermentable fiber increases the production of gut bacteria that produce butyrate, an immune function stimulator. Fermentable fiber comes from sweet potatoes, yams, plantains, taro, potatoes, onions, Jerusalem artichokes, and garlic.

Administering T3 alone without T4 results in accelerated weight loss, improved lipid management, and adequate cardiovascular health. Neurodegenerative disease processes slow, moods stabilize, and cognition improves.
