the thyroid | a balancing act


Sometimes you just feel ‘off’. You’re slightly off-balance and can’t explain it. It may be a feeling of fatigue that just won’t go away, even after a full night’s sleep. Or maybe you’re feeling depressed or anxious without a rational cause. And even though you’ve been consistent with your diet and exercise, the pounds have somehow piled on pounds that just won’t budge. All of these symptoms can possibly point to a thyroid disorder. 

To learn more about this delicate gland and its functions we share with you an excerpt from an in-depth article that Dr Faryal our in-house Naturopthic Doctor put together: 

Countless individuals suffer from symptoms of low or dysfunctional thyroid and countless more are misdiagnosed or undiagnosed.  Doctors either interpret lab values incorrectly or determine that these patients are “fine” because they do not fit into the conventional reference ranges on standard panels. Thyroid problems in women occur up to 7 times more often than in men, and globally, a staggering 200 million people are living with related disorders. 

The thyroid is a butterfly-shaped gland which sits just below the voice-box in the neck and is responsible for producing hormones which regulate growth and energy production in the body, making it the master gland of metabolism. But that’s not all; the thyroid influences and interacts with other hormones in the body and is essential for proper functioning of all organs including the heart, musculoskeletal system, and brain. 

High or Low? 

Hypothyroidism and Hyperthyroidism are at opposite ends of the spectrum of thyroid disease. A healthy thyroid gland is initially governed by the pituitary gland in the brain, which senses low thyroid hormone in the blood and sends a messenger to instruct the thyroid to make more hormone.  This messenger is TSH or thyroid stimulating hormone.  An underproduction of these hormones will slow down metabolism resulting in Hypothyroidism which creates symptoms such as weight gain, feeling cold, fatigue, irregular menstruation, brain fog, depression, increased blood pressure and cholesterol, dry skin, hair loss and constipation.  On the other hand, overproduction leads to Hyperthyroidism which speeds up the body’s metabolism.  Classic features include weight loss, nervousness, anxiety, intolerance to heat, excessive sweating, palpitations and insomnia. 

Get the correct Tests 

Most physicians believe that the patient is fine if TSH values are within the “normal” range, however the TSH value is grossly unreliable at determining low thyroid function.  Often patients are given prescription medication for low thyroid or dismissed entirely because their TSH and T4 levels are “normal” according to the conventional understanding. 

The upper limit for TSH accepted conventionally is between 4 and 5 mU/L.  However, from a naturopathic perspective, the acceptable upper limit is 2.5 mU/L, with most patients feeling best at 1.5-2 mU/L.  This discrepancy of opinion is one of the main factors resulting in underdiagnoses which affects health and quality of life. 

Measuring free T3 and free T4 levels is essential.  Fluctuating levels along with TSH measurements can distinguish between cellular resistance to active T3 or conversion problems from T4 to T3. 

Thyroid antibodies must also be tested to ascertain any autoimmune issues and is the best way to diagnose Hashimoto’s.  The common antibodies tested are Anti-TPO (thyroid peroxidase) and Anti-TGA (thyroglobulin). 

Finally, reverse T3 testing is crucial as it is the third most abundant form of thyroid hormone. Active T3 can sometimes be diverted back into an inactive “reserve” form which happens during times of illness or stress. This is worth checking when fT3 is low but fT4 and TSH are normal.          

Treat the Cause 

The physiology of this gland is complex and is interconnected with other endocrine glands, immune system, the gut, and various cellular signals A multitude of factors influence thyroid function, which if overlooked, may worsen the condition. Some of these factors are: 

Stress an inescapable part of modern day life and a major contributor toward thyroid issues.  Chronic or high stress elevates cortisol which when prolonged, fatigues the pituitary and adrenal glands and interferes with TSH.  Many overweight individuals attribute weight gain to low thyroid function, not realizing the connection to high stress and cortisol levels which further inhibit weight loss.   

Conversion of T4 into T3– Most thyroid patients receive a medication called Thyroxin which is mostly T4; this is not effective if conversion into T3 is problematic. T4 comprises 90% of thyroid hormone, however up to 60% of conversion into the active T3 form takes place in the liver. A sluggish liver despite normal liver enzymes on lab tests, will impede conversion.  Toxins from the environment and food need to be detoxified effectively by the liver, so naturopathic support for the liver may be needed. Another twenty percent of the conversion into T3 takes place in the gut so healthy digestive function is vital as well.   

Mineral and vitamin deficiencies these are common since iodine (present in T3 and T4), selenium, iron and even Vitamin D are all necessary for proper thyroid function and are involved in converting T4 into T3.  Tyrosine, zinc and methylfolate are also major players, which if deficient, can lower T3.   

Hormonal imbalances in particular excess estrogens from birth control pills, xenoestrogens from plastics and toxins in the environment, hormone-injected meats – all lower thyroid hormone. Hormones interact with each other and excess estrogens interfere by increasing the protein that binds to thyroid hormone (TBG) making it inactive. 

Naturopathic management always aims to treat the root cause. Diet is the foundation, and specific nutrients and natural medicines are used to regulate and restore thyroid function as well as to clear dysbiosis and improve gut function.
