The Thyroid - Toxin - Gut Connection

So many women I work with come to me with digestive concerns. But, along the way we also uncover thyroid, hormone and blood sugar imbalances. So, I want to take a moment to address the thyroid-toxin-gut connection.

I consider thyroid dysfunction to be a “canary in coal mine” when it comes to toxic burden on the body and it usually is a trigger of thyroid issues — along with nutrient deficiencies and often a stressful life event.  

A functional medicine approach:

Functional medicine nutrition recognizes the important connection between thyroid health, gut health, and toxins in the body. The thyroid gland, located in the neck, produces hormones that regulate metabolism and energy production in the body.   When the thyroid is not functioning optimally, it can lead to a range of health problems, including weight gain, fatigue, depression, anxiety and digestive issues (usually constipation if the thyroid is sluggish or diarrhea if it’s overactive). 

The gut and thyroid are closely connected through a complex network of hormones and enzymes. Poor gut health, like leaky gut, can disrupt this connection and lead to thyroid problems and probably other digestive and autoimmune symptoms as well.   In addition, toxins in the body, including heavy metals, mold mycotoxins, pesticides, and chemicals coming from our food, air, water, home and personal care products, can interfere with thyroid function and contribute to autoimmune thyroid disorders like Hashimoto's. 

A Functional medicine nutrition approach to thyroid, gut, and toxin-related health problems is holistic and personalized. It identifies the root causes through lab testing and a thorough clinical intake. Treatment typically involves a combination of diet and lifestyle modifications, supplements, and detoxification protocols to support optimal thyroid function and improve gut health. 

What you can do:

  • An anti-inflammatory diet rich in colorful, nutrient-dense foods like vegetables, fruits, herbs and spices, healthy fats, and protein is a great place to start. 

  • Supplements such as probiotics, digestive enzymes, minerals and nutrients like selenium and zinc are also a great starting point for a lot of people.

  • Detoxification strategies such as sauna, sweating, castor oil packs and making sure you’re pooping regularly may also be recommended to remove toxins from the body and reduce the burden on the thyroid gland along with binders and liver supporting herbs.
