How Your Gut Microbiota Affects Your Thyroid

How Your Gut Microbiota Affects Your Thyroid

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.

Ashwagandha, Hashimoto’s Disease, and Subclinical Hypothyroidism

Ashwagandha, Hashimoto's Disease, and Subclinical Hypothyroidism

Ashwagandha is one of my favorite supplements for Hashimoto’s disease and hypothyroidism and we have some excellent studies to support using it for these conditions.

The main study I’ll cover in this research review is entitled, “Efficacy and Safety of Ashwagandha Root Extract in Subclinical Hypothyroid Patients: A Double-Blind, Randomized Placebo-Controlled Trial” published in The Journal of Alternative and Complementary Medicine. We’re already off to a good start just by reading the title which indicates that it is a double-blind, randomized placebo-controlled study so we know it is of the highest standard.

The Hashimoto’s Disease and SIBO Connection

Hashimoto's Disease SIBO Connection

Is there a connection among Hashimoto’s disease, hypothyroidism, and small intestinal bacterial overgrowth also known as SIBO? Does Hashimoto’s disease cause SIBO or does SIBO cause Hashimoto’s? I’ll answer these questions in my latest research review below.

There isn’t a lot of research, only two papers actually, on the specific connection between Hashimoto’s disease and SIBO which I’ll cover in this article. There are more papers on the connection between hypothyroidism and SIBO without mention of Hashimoto’s and the basic conclusion of those papers is that hypothyroidism is connected to SIBO because gastric motility is decreased in hypothyroidism. Decreased gastric motility basically means the food you eat is moving through the bowels to slowly so bacteria can build-up in the small intestine.

Can Blastocystis Hominis Cause Hashimoto’s Disease?

Blastocystis Hominis Hashimoto's Disease

Our discussion today revolves around a microscopic parasite called Blastocystis hominis, a case of hives and Hashimoto’s disease!

The case report was published in 2015 in The Journal of Infection in Developing Countries.  The report was entitled, “Eradication of Blastocystis hominis prevents the development of symptomatic Hashimoto’s thyroiditis: a case report.  The case involved a singular subject who was suffering from chronic urticaria (hives), angioedema (skin swelling) and overly soft stools who also showed signs of Hashimoto’s disease.

But before we delve into more details, let me provide you with some basic background information.

Healing Hashimoto’s Disease with Andrea Nakayama

Andrea Nakayama Hashimoto's Disease
In this episode of The Dr. Hedberg Show, I interviewed Andrea Nakayama in a discussion about strategies for healing Hashimoto’s disease.  We talked about her “3 Tiers to Epigenetic Mastery” and how they relate to Hashimoto’s disease and thyroid health.  Within the 3 tiers we discussed stress, gut health, infections, micronutrient deficiencies, adverse childhood experiences, SIBO, reproductive hormones, goitrogens, iodine, and all the various diets that people are following these days.
Andrea is a clinician but also a Hashimoto’s patient so it was a real pleasure to get her insight and expertise on healing Hashimoto’s disease.

The Truth About Fluoride with Melissa Gallico

Melissa Gallico Fluoride
In this episode of The Dr. Hedberg Show, I interview Melissa Gallico about fluoride.  We talked about where fluoride comes from, why it was added to our water supply, how to know if your water is fluoridated, how to filter fluoride, other sources of fluoride, the fluoride-acne connection, the fluoride-thyroid connection, how to detoxify fluoride with iodine, and how to petition your local legislators to remove fluoride from your water supply.  I was not aware of the fluoride-acne connection so this was an enlightening podcast that everyone should listen to who has acne or a thyroid issue.

Hashimoto’s Food Pharmacology with Dr. Izabella Wentz

Hashimoto's Food Pharmacology Dr. Izabella Wentz

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.

Ferritin and Hypothyroidism

Ferritin and Hypothyroidism

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.

The Iodine Crisis with Lynne Farrow

Lynne Farrow Iodine Crisis

In this episode of The Dr. Hedberg Show, I interview Lynne Farrow the author of the book, “The Iodine Crisis:  What You Don’t Know About Iodine Can Wreck Your Life.”  We had an in-depth discussion about iodine and how important it is for your body.  We covered many topics including why iodine deficiency is so prevalent, bromide, fluoride, sources of iodine, the best iodine supplements, how to test for iodine deficiency, breast cancer, iodized salt, goiters, iron and ferritin, hypothyroidism, Hashimoto’s disease, seaweed, and conditions associated with iodine deficiency.

Genistein and Hashimoto’s Disease

Hashimoto's Disease

Can Genistein Help Heal Hashimoto’s Disease and Hypothyroidism?

In the fall of 2016, a study was conducted in China and published in the medical journal Immunobiology. The researchers looked at the compound genistein and Hashimoto’s disease to see if it affected thyroid function in patients with Hashimoto’s thyroiditis.  The research paper was entitled, “Genistein improves thyroid function in Hashimoto’s thyroiditis patients through regulating Th1 cytokines.”  To clarify, “Th1 cytokines” refer to a type of thyroid-helper cells that indicate how much inflammation there might be in the thyroid gland.  In other words, they are markers of inflammation.

The results of this study were very exciting so you might want to pay close attention.
