The Basics of An Epidemic
What do chronic pain, diabetes, heart disease, menstrual difficulties, and sleep apnea have in common? As physician Mark Starr points out in his extensively researched book, Hypothyroidism Type 2: The Epidemic, there’s an excellent chance that this apparently disparate collection of disorders—among literally dozens, if not hundreds—indicate abnormally low thyroid function.
The thyroid is a butterfly-shaped endocrine gland located at the throat that produces numerous related hormones: thyroxin (also known as T4), liothyronine (also known as T3), T2, and T1. T4, the most well known of all the thyroid hormones, heats the body and speeds metabolism (of fats, proteins and carbohydrates) and heart rate. T3, the most active form of thyroid hormone, also heats the body and speeds metabolism and heart rate. At best, T4 is only about one-quarter as potent as T3, and in any case most is converted into the more active T3 by the liver, kidneys, and other body cells. T2 stimulates metabolism, while one animal study showed that T1 cools the body and slows the heart. Together, all four of these related hormones probably act synergistically in ways that are not yet fully understood.
Thyroid underactivity, commonly called hypothyroidism, was first reported in London in 1875. According to many reliable sources, including doctors Broda Barnes, David Derry, Jacques Hertoghe, and James Howenstine, at least one-third to one-half of the US population suffers from slight to severe hypothyroidism.
In his book, Starr explains the differences between Types 1 and 2.
Laboratory tests showing inadequate bloodstream levels of thyroid hormone make it easy to diagnose Type 1 hypothyroidism. However, lab tests fail to detect Type 2 hypothyroidism, because despite adequate bloodstream hormone levels, the cells are unable to accept and utilize that hormone (for a variety of reasons, which I'll address in a moment). Since the main problem lies with the cells that are actually utilizing the hormone, a different approach needs to be taken when testing for (and to a certain extent, when treating) Type 2 hypothyroidism.
Since many more people suffer from Type 2 than Type 1 hypothyroidism, and because Type 2 is widely misunderstood and misdiagnosed, this article will focus on Type 2: its manifestations, the best way to diagnose it (it's not with lab tests), and its treatment. For this article, I have drawn heavily from Mark Starr's book, Hypothyroidism Type 2: The Epidemic.
Dr. Starr became interested in the subject for both personal and professional reasons. More than a dozen years ago, he embarked on a quest to heal his own chronic pain, fatigue and allergies after receiving no relief from the majority of physicians with whom he consulted. Professionally, while treating thousands of people who suffered chronic pain alongside a wide range of disorders, he discovered a pattern. The underlying cause or contributing factor to their pain was low thyroid function. Dr. Starr's book is the result of over a decade's worth of intensive research and writing about the history, problems, politics, personnel, literature, case studies, and treatment related to hypothyroidism. I had the opportunity to visit Starr's new clinic, which is near my home, so at the end of this article I will also give a brief description of his practice.
