Dysfunctional thyroid disorders are one of the most commonly undiagnosed conditions in young to middle-aged adults and can have an enormous impact on health and well being. Many people complain of “thyroid symptoms” even though their doctor tells them that their lab values are normal. We find that thyroid function is much more involved than one or two blood tests. And when additional thyroid markers are evaluated a subtle trend or pattern emerges. In addition, there are a number of mechanisms independent of the thyroid that interfere with thyroid function, conversion of thyroid hormone in the body and receptor site interaction and hormone sensitivity. Some of the more common overlooked mechanisms that interfere with thyroid function include hidden food sensitivities, poor nutrition, consuming inflammatory foods on a regular basis and environmental toxicity. When these functional mechanisms are addressed we observe patients report fewer thyroid symptoms even if their lab values remained relatively unchanged.
