Congenital Hypothyroidism

From: altaelpl91 - 2 years 44 weeks ago


I am a female in my mid twenties diagnosed with congenital hypothyroidism. I have been on Synthroid since I was two weeks old. Ultrasounds have shown that have a small amount of thyroid tissue but that no actual thyroid gland was ever present. I check my labs annually and sometimes need minor dosage adjustments. I am extremely into living a healthy lifestyle and that includes eating a variety of foods. Over the past few years I have taken more interest into my thyroid disorder, however my search research only finds information about Hashimoto disorder. I am aware of the effects of too much fiber, soy, cruciferous vegetables, etc. What I am confused about is whether or not this applies to the functioning of the thyroid or just the absorption of the Synthroid. I take my medicine first thing in the morning with a glass of 8 oz water. I typically have eggs for breakfast 30-45 minutes later. Then an hour or two later I have oatmeal or cereal. I love to eat cruciferous vegetables during the day or for dinner. Over the past few years I have been avoiding some of these foods because of what I have read. I recently moved to another country that incorporates rye into nearly every meal. I began to indulge in lots of yummy and so healthy for you rye bread everyday! If I continue to take my medicine early and hours prior to any consumption of these foods will my thyroid levels remain stable? Do these foods apply to my Congenital Hypothyroidism? Additionally, I would like to start taking Rainbow Light Organic Women's Multivitamin but they contain kale, spinach, and some other thyroid no no's. I need some clarification!

Thank you!

Is this good advice?

The dietary changes recommended for thyroid conditions applies to the functioning of the thyroid. If you are taking your Synthroid away from food as you described, you should be fine. HOWEVER, and this is a big however, Synthroid contains only the T4 hormone. T4 converts to T3 in the body, but this conversion does not happen well or at all in many people. Much of this conversion takes place in the liver, which means your liver should be clean and functioning optimally (detox it with the change of each season, etc.) to help the conversion along. This explains why SO many women on Synthroid only feel a LITTLE better. It's because they are still lacking the active T3 hormone. Going gluten free is excellent for thyroid health. So much could be said on this topic, but I hope this is helpful. If you are looking for health consulting, feel free to reach out to me at

Also, cruciferous veggies are not all bad for the thyroid. Studies have shown that in moderation they have not affected thyroid function. So I would say your vitamin is fine. You do, however, want to avoid things that cause antibodies to the thyroid. These would include stress, toxins, gluten, chemical exposure, and often dairy. Sometimes childbirth in itself can throw the body into postpartum thyroiditis. I would approach this with the same things mentioned above.
