Myth: Thyroid medicine will damage the thyroid gland if the thyroid tests are normal

If a person is given thyroid medicine when the thyroid blood tests are normal, or when the thyroid gland is normal, it will damage the thyroid gland.

FALSE. Whereas thyroid medicine can rest a person’s thyroid system for a time no studies have ever shown that it can damage a previously healthy gland, preventing it from functioning normally again after the medicine is discontinued. Actually, resting the thyroid system in the right way can often reset it, much like birth control pills can suppress a woman’s own female hormone system for a time to restore a normal menstrual cycle. For example, the thyroid gland function of patients who come in with their thyroid glands suppressed with thyroid medicine for the past 20 years routinely have their own thyroid gland function come back up again when they’re weaned off.

About the Author:

Denis Wilson, MD developed the concept of Wilson 's Temperature Syndrome in 1988 after observing people with symptoms of low thyroid and low body temperature, yet who had normal blood tests. He found that by normalizing their temperatures with T3 (without T4) their symptoms often remained improved even after the treatment was discontinued.

    Hi Dr Wilson,
    I have an extreme case of eczema and itching for four years. I am 50 years old and have dry skin, bad nails, thinning hair, low body temps and chronic constipation. I am slender but it takes a lot to stay that way. I live an very healthy lifestyle and have just below normal thyroid levels. Do you have patients that have eczema? If so, have they been helped with thyroid medications or support?
    Thank you for your input!

      I have not seen eczema in many patients with low temperatures.
      But I have seen patients with various skin disorders.
      Eczema has been observed in patients mostly with thyroid function that is too high.
      However, low thyroid and high thyroid problems can have thyroid antibodies which are found in many autoimmune diseases.
      So I think it’s possible it could respond but I haven’t seen it a lot.
      Best :)
      Dr. Wilson
