If you’ve been researching how to manage your thyroid and hormones, chances are you’re heard of leaky gut. Leaky gut is what it sounds like — the lining of the intestines have become “leaky,” allowing undigested foods, bacteria, and other undesirables into the sterile bloodstream.
This causes system-wide inflammation that becomes chronic health issues: autoimmune diseases such as Hashimoto’s hypothyroidism, chronic pain, brain fog, food allergies and sensitivities, depression, eczema, asthma, and myriad other complaints.
It makes sense, then, that people need to heal leaky gut in order to manage thyroid symptoms.
However, it’s best to know why you have leaky gut first. That way you’re not chasing down the wrong remedies.
Ten causes of leaky gut that worsen your thyroid and hormone symptoms
Although we understand the role of leaky gut in chronic health disorders, the underlying causes of leaky gut itself can be harder to pin down.
Here are the causes we know about:
Many inflammatory foods damage the intestinal walls, leading to leaky gut. Gluten in particular is associated with leaky gut. Dairy, processed foods, excess sugar, and fast foods are other culprits.
Excess alcohol is another common cause of leaky gut.
Prescriptions and OTC Medicines
Some medications cause leaky gut, including corticosteroids, antibiotics, antacids, and some medications for arthritis It’s important to note some drugs have inflammatory fillers such as gluten.
Certain infections, such H. pylori overgrowth (the bacteria that causes ulcers) or small intestinal bacterial overgrowth (SIBO) can cause leaky gut. Yeast, parasites, and viruses are other possibilities.
Chronic stress raises stress hormones, which damages the gut lining over time.
Hormone imbalances can cause leaky gut as the intestines depend on proper hormone levels for good function. Imbalances in estrogen, progesterone, testosterone, thyroid hormones, and stress hormones all contribute to leaky gut.
We often think in terms of leaky gut causing autoimmune diseases such as Hashimoto’s hypothyroidism, rheumatoid arthritis, or psoriasis. However, sometimes it’s the other way around. The constant inflammation of autoimmune disease can make the gut leaky. Or autoimmunity in the digestive tract can sabotage gut health. In these cases, managing autoimmunity is a strategy to improve leaky gut.
Food processing changes the natural structure of foods in a way that makes them inflammatory to the gut. Examples include deamidating wheat to make it water soluble and the high-heat processing (glycation) of sugars. Additives such as gums (xanthan gum, carrageenan, etc.), food colorings, and artificial flavors are inflammatory for some people, too.
Our environment surrounds us with toxins, some of which have been shown to degrade the gut lining. Regularly taking glutathione, the body’s primary antioxidant, helps protect the body from toxins.
Vitamin D Deficiency
Sufficient vitamin D is vital to protecting the gut lining and a vitamin D deficiency can make the intestinal lining more vulnerable to damage.
These are some of the factors known to contribute to leaky gut and flare or exacerbate Hashimoto’s hypothyroidism. By understanding the cause of your leaky gut and Hashimoto’s hypothyroidism, you will have more success restoring health to your gut and managing your autoimmune thyroid condition.
