The National Institutes of Health (NIH) states that five out of every 100 Americans over the age of 12 have hypothyroidism. The prevalence of this disease increases with age.(1) This makes hypothyroidism the most common disease arising from a hormonal insufficiency.(2) Gender is an influencing factor, as women are three to seven times more likely to develop hypothyroidism than men.(1) Known risk factors that increase the likelihood of developing this disease include having a family history of hypothyroidism and pregnancy.(1) Recent research by the British Medical Journal (2021) suggests that taking birth control pills, or oral contraceptives (OCs), may also increase the odds of developing hypothyroidism.(3)
In this episode of Functional Medicine Research, I interview Sally Norton in a discussion about how oxalates affect your thyroid and your health. We covered what oxalates are and how they can damage the body. We also discussed how oxalates affect gut health, liver health, thyroid health as well as all the symptoms and associated conditions connected to oxalates.
If you’re really struggling to get well, but your diet appears to be healthy, oxalates may be the missing link.
We have known since the early 1970s that infections can trigger autoimmune diseases and now we have an interesting hypothesis on the potential triggering of Hashimoto’s disease by COVID-19 infection.
A recent case study out of Singapore published in the Singapore Medical Journal entitled, “COVID-19 complicated by Hashimoto’s thyroiditis” presents an individual who developed Hashimoto’s thyroiditis after contracting COVID-19.
COVID-19 can cause a hyperinflammatory state in the body which is a potential recipe for developing autoimmune disease. The authors begin by pointing out the most current literature on COVID-19 connections to the autoimmune diseases antiphospholipid syndrome, autoimmune thrombocytopenia, autoimmune hemolytic anemia, and Guillain-Barre syndrome.
There have never been any studies on leaky gut and Hashimoto’s disease but now we have a new study on this connection. Leaky gut was something rejected by conventional medicine despite the fact that papers on leaky gut date back to the 1970s. For many years functional medicine practitioners have been testing for it and treating it which has helped many patients overcome their chronic illnesses. There are currently over 500 published scientific papers on leaky gut so there is no doubt it exists.
The connection between iodine and Hashimoto’s disease has been one of the most requested topics that I cover, so I’d like to present the research on this topic, so we can set the record straight. Please be aware that none of this is my opinion but rather a detailed analysis of what the scientific literature currently presents.
Your body has about 15 to 20 mg of iodine and 70 to 80% of it resides in the thyroid gland. Iodine is transported into the thyroid gland through the sodium-iodine symporter or NIS. The thyroid peroxidase enzyme oxidizes iodine which is then integrated into thyroglobulin resulting in the production of thyroxine (T4) and triiodothyronine (T3). Thyroid stimulating hormone (TSH) regulates this process.
Your thyroid only needs 150 to 250 micrograms a day of iodine to function properly. Once iodine intake exceeds this range, hypothyroidism and autoimmune thyroid disease may occur in some individuals.
Your gut microbiota has an intimate connection with your thyroid including connections with hypothyroidism, Hashimoto’s disease and Graves’ disease. In this research review I’d like to cover a recent paper entitled, “Microbiota and Thyroid Interaction in Health and Disease” published in the journal Trends in Endocrinology and Metabolism by Eleonare Frohlich and Richard Wahl.
The authors begin by stating that the gut microbiota can act on thyroid function due to the region of where someones lives, their diet including iodine intake, obesity, age, sex hormones, and how autoimmunity can impact the microbiota. I was impressed to see them state that the gut microbiota is linked to autoimmune disease, estrogen, iodine, and obesity. Estrogen can be a key factor in Hashimoto’s disease and a healthy gut is required for optimal estrogen metabolism and excretion through the feces.
They also mention the connection between the gut and the liver in relation to thyroid hormone metabolism in both these organ systems. Your gut is key to properly absorbing and utilizing the thyroid medication that you’re taking and they mention this as well.
In this episode of The Dr. Hedberg Show, I interview Dr. Izabella Wentz about her new book, “Hashimoto’s Food Pharmacology.” We had a great talk about Hashimoto’s disease, Dr. Wentz’s Hashimoto’s healing journey, foods that can help heal Hashimoto’s disease, green smoothies, bone broth, and some recipes that can help heal Hashimoto’s disease.
I highly recommend all of Dr. Wentz’s books and her new book will help you make food easier and healthier so you can heal your Hashimoto’s disease.
In this post I’ll cover everything you need to know about ferritin and hypothyroidism. The ferritin test is a simple blood test and it is one of the most important tests you should have if you have Hashimoto’s disease, Graves’ disease, and hypothyroidism. Ferritin is a storage form of iron and the ferritin level test can tell you if your iron stores are low and need to be increased. The ferritin test is rarely ordered by conventional doctors so many patients are left with the signs and symptoms of hypothyroidism when it is actually their low ferritin levels that are causing their health problems. The first issue with iron is that iron deficiency may be quite severe but blood markers such as hemoglobin and the red blood cell count may be normal. This leaves many patients, especially women, misdiagnosed as not having anemia.
