• Worldwide, iodine deficiency remains the most common cause of hypothyroidism, whereas in industrially developed parts of the world autoimmune hypothyroidism (Hashimoto’s disease) is the most common thyroid disease.
  • There is considerable controversy over diagnosing hypothyroidism. The goals of treatment should involve both objective measures (e.g.,TSH) and symptoms.
  • Correcting deficiencies of iodine, selenium, Vitamin A, iron, and zinc can improve or resolve concurrent hypothyroidism and enhance conversion of T4 to T3.
  • Excessive intake of iodine can also cause hypothyroidism.
  • Reduction of excessive dietary goitrogens such as brassica vegetables, soy, cassava and millet should be considered for hypothyroid patients. Cooking may minimize the goitrogenic effects of brassica and soy.
  • Combined T4 and T3 (such as porcine thyroid or co-administered liothyronine plus levothyroxine in a 1:4 ratio) may have benefit over synthetic T4 alone in select patients, but widespread use is unlikely to provide additional benefit.
  • Ground porcine thyroid is a safe alternative for patients wanting a more “natural” treatment. 1 grain (60 mg) of Armour Thyroid is equivalent to 100 mcg of levothyroxine, and TSH may be used as usual to monitor therapy.
  • In the hands of competent practitioners, yoga and hydrotherapy are two relatively safe but speculative ways of improving hypothyroidism.
