Thyroid hormone replacement has been used for more than a century to treat hypothyroidism. Natural thyroid preparations (thyroid extract, desiccated thyroid, or thyroglobulin), which contain both thyroxine (T4) and triiodothyronine (T3), were the first pharmacologic treatments available and dominated the market for the better part of the 20th century. Dosages were adjusted to resolve symptoms and to normalize the basal metabolic rate and/or serum protein-bound iodine level, but thyrotoxic adverse effects were not uncommon. Two major developments in the 1970s led to a transition in clinical practice: 1) The development of the serum thyroid-stimulating hormone (TSH) radioimmunoassay led to the discovery that many patients were overtreated, resulting in a dramatic reduction in thyroid hormone replacement dosage, and 2) the identification of peripheral deiodinase-mediated T4-to-T3 conversion provided a physiologic means to justify l-thyroxine monotherapy, obviating concerns about inconsistencies with desiccated thyroid. Thereafter, l-thyroxine mono-therapy at doses to normalize the serum TSH became the standard of care. Since then, a subgroup of thyroid hormone–treated patients with residual symptoms of hypothyroidism despite normalization of the serum TSH has been identified. This has brought into question the inability of l-thyroxine monotherapy to universally normalize serum T3 levels. New research suggests mechanisms for the inadequacies of l-thyroxine monotherapy and highlights the possible role for personalized medicine based on deiodinase polymorphisms. Understanding the historical events that affected clinical practice trends provides invaluable insight into formulation of an approach to help all patients achieve clinical and biochemical euthyroidism.
Exercise: Many patients with hypothyroidism have reported benefits from practicing a yoga pose called the Shoulder Stand, or sarvangasana, which increases circulation to the thyroid. Lie on your back with your arms (palms up) along your sides. Raise your legs at a right angle to the floor. Then raise your hips so your chin rests on your chest, supporting yourself with your elbows and upper arms on the floor and your hands on your hips. Keep your neck and shoulders flat on the floor, and stretch your torso and legs as straight as possible. Hold as long as comfortable, slowly working up to 5 minutes a day. Don’t do this pose if you are pregnant or menstruating, nor should you try it if you have glaucoma, sinus problems or high blood pressure. The Shoulder Stand may be more effective if you use visualization practices, imagining the thyroid gland waking up from a long period of inactivity and producing more thyroid hormone.
Try this: Cut apples crosswise (don’t peel them—the skin is the richest source of pectin!), dredge in brown sugar, then pan-fry in coconut oil until tender; top with shredded basil and crumbled blue cheese. Spiralize a whole apple with skin, lightly steam in apple juice until tender, and serve with yogurt, hemp seeds, and blueberries as a breakfast noodle bowl. Simmer chopped apples, parsnips, shallots, and sprigs of thyme in broth until tender; remove thyme sprigs and purée until smooth; top with additional thyme and a dollop of crème fraîche.
“The effects of fluoride on various aspects of endocrine function should be examined, particularly with respect to a possible role in the development of several diseases or mental states in the United States. Major areas of investigation include . . . thyroid disease (especially in light of decreasing iodine intake by the U.S. population).” (National Research Council, 2006)
Megan Casper, RDN, a dietitian based in New York City and the founder of Nourished Bite, points out that iodine deficiency is the leading cause of hypothyroidism worldwide. This mineral can’t be made by the body, so dietary sources like iodized salt, dairy products, seafood, seaweed, and fortified cereals are important. “Iodine is an essential nutrient in the body, and thyroid hormones are composed of iodine,” explains Rizzo. “Those lacking thyroid hormones may also be lacking iodine.”
