Your thyroid is a small, butterfly-shaped gland located in the lower front part of your neck. Its job is to secrete hormones that control growth/development during childhood, regulate your metabolism and body temperature, and drive the production of many neurotransmitters in your brain. Specifically, the ones that help you feel good and enough have motivation to accomplish your goals: serotonin, dopamine, adrenaline, and noradrenaline.
It’s estimated that tens of millions of people worldwide have thyroid problems—anywhere from 5-25% of the world’s population. In the book, Thyroid Mind Power, it’s reported that, “the last 40 years have witnessed a massive increase in the amount of hormone-disrupting synthetic chemicals, finding their way into our air, food and water…The most sensitive and highly susceptible of human tissues turned out to be the thyroid gland.”
Important Thyroid Facts
Factors that Inhibit Healthy Thyroid Function and impair conversion of inactive T4 to Active T3:
Thyroid problems are increasing in the population and especially among women, often surfacing after pregnancy and during middle age. It’s estimated that 1 out of 4 postmenopausal women has thyroid imbalances, and according to Ridha Arem, M.D., editor of the journal, Thyroid, nearly 45% of people over 50 have some degree of thyroid gland inflammation, which is an early sign that thyroid imbalance is likely to occur.
Thyroid imbalance is a major cause of depression, anxiety, mental fog, and memory issues:
The two most common thyroid imbalance issues are hypothyroidism and hyperthyroidism:
Suspect Thyroid Imbalance?
It’s difficult to know if your thyroid is truly balanced without a simple blood test, which is something that your primary care physician should be willing to provide. The main thyroid hormones—TSH, T3, and T4—all have to be in the right balance for you to feel your best.
Blood Test Checklist
When your doctor checks your thyroid, don’t settle for a TSH test alone—it only measures your thyroid stimulating hormone. TSH levels can be normal, even while you have an undiagnosed thyroid problem. Instead, if you have any symptoms, insist your doctor order the following tests:
Balancing Your Thyroid
Thyroid issues can be effectively treated with a number of thyroid medications, but your doctor needs to test your levels regularly to assure that you are not taking too much or too little.
There are also a number of natural dietary supplements that support thyroid function, including the herb rosemary, Magnesium, Manganese, zinc, chromium, potassium, iodine, l-tyrosine, vitamins A, B2, B3, B6, B12, C, D, Vitamin E, CoQ10, selenium, seaweed, and ashwagandha. Also, make sure to have healthy testosterone, insulin, and melatonin levels.
While these thyroid tests can be helpful, in the final analysis your doctor should treat YOU, not the blood test. We have seen many women with hypothyroidism not treated by their physicians because their thyroid numbers were low but “within normal limits.” It’s a little like saying a vitamin D level of 21 is normal (normal range is 20-80).
How you feel and how you function (e.g., energy, constipation, dry hair, dry skin, cognition, body temperature) is more important in assessing thyroid function than just using arbitrary blood test normal ranges.
