Leaky gut syndrome may be the hidden culprit behind a wide range of frustrating health issues—from digestive troubles and brain fog to skin conditions, mood swings, and even autoimmune diseases. In this blog, we’ll dive into what leaky gut is, what causes it, and the most common leaky gut symptoms to watch out for. You’ll also learn how to test for intestinal permeability, how symptoms of leaky gut can impact your overall health, and the steps you can take to begin the healing process naturally.

Amy Myers, MD
Before I became a physician, functional medicine expert, and 2x New York Times best selling author, I desperately struggled with gut issues, autoimmunity, and chronic symptoms that nearly destroyed my life. Thankfully, I took back control of my health. Conventional medicine failed me and it is my mission to not have it fail you too.

There’s a connection between gluten and thyroid health, particularly for individuals with autoimmune thyroid conditions such as Hashimoto’s and Graves’ disease. Research suggests that gluten can contribute to leaky gut, a condition that allows harmful substances to enter the bloodstream, triggering an immune response that may mistakenly attack the thyroid. This process, known as molecular mimicry, occurs because gluten proteins resemble thyroid tissue, leading the immune system to target both. Eliminating gluten from the diet can reduce inflammation, support gut repair, and improve thyroid function, making it a crucial step for those managing thyroid disease.

Struggling with persistent eczema? Conventional eczema treatment often focuses on symptom relief rather than addressing the root causes. Functional medicine takes a different approach, identifying gut health and inflammation as key factors in eczema flare-ups. You can reverse your eczema symptoms by healing your gut, reducing inflammatory triggers, and restoring your microbiome. A tailored eczema treatment plan, including dietary changes, probiotics, and gut-repairing supplements, can help soothe your skin from the inside out. Take control of your eczema today with the functional 4R approach that promotes lasting skin and gut health.

Brain fog can stem from various causes, including stress, poor sleep, hormonal imbalances, and dietary deficiencies. Factors such as high sugar intake, refined carbohydrates, and vitamin B12 deficiency can contribute to cognitive sluggishness. Additionally, conditions such as thyroid dysfunction, gut imbalances, and chronic inflammation may play a role. Identifying and addressing the root causes of brain fog—whether through improved nutrition, stress management, or better sleep—can help restore mental clarity and focus.

The causes of leaky gut stem from various factors, with diet playing a significant role. Inflammatory foods such as gluten, dairy, refined sugars, and nightshades can weaken the gut lining, while toxic substances like alcohol, artificial sweeteners, and processed foods exacerbate the issue. Chronic stress, environmental toxins, and gut infections like Candida overgrowth or SIBO further contribute to increased intestinal permeability. When the gut barrier is compromised, undigested food particles and toxins leak into the bloodstream, triggering immune responses that may lead to inflammation and autoimmune diseases. Identifying and eliminating these triggers is crucial for gut health restoration.

Thyroid hair loss can be a frustrating and disheartening symptom of thyroid dysfunction, often caused by hormonal imbalances, nutrient deficiencies, and chronic stress. By optimizing thyroid hormone levels, improving diet, and supporting adrenal health, you can address the root causes of thyroid hair loss and restore healthy, vibrant hair naturally. Implementing targeted lifestyle changes and incorporating essential nutrients such as iron, selenium, and iodine can help you regain not only your hair but also your overall well-being.

Gluten intolerance has become increasingly common, potentially due to modern farming practices that prioritize yield over nutritional quality. Unlike celiac disease, which is an autoimmune disorder, gluten intolerance does not cause intestinal damage but can still trigger symptoms like bloating, brain fog, joint pain, and fatigue. Some research suggests that gluten may contribute to inflammation and exacerbate autoimmune conditions. The best way to determine sensitivity is through an elimination diet, where gluten is completely removed and then reintroduced to observe any reactions. Managing gluten intolerance requires strict avoidance, label checking, and sometimes supplements to aid digestion and detoxification.

Ever wonder what causes cancer? While genetics play a small role (5-10%), modern lifestyle factors significantly contribute to cancer, supporting the view that it is a metabolic disease. Key causes include processed foods, gut health issues, chronic infections, toxins, radiation, stress, and metabolic disorders. Poor diet, environmental toxins, and sedentary lifestyles increase acidity, inflammation, and oxidative stress, creating an environment for cancer to thrive. Conventional treatments focus on surgery, chemotherapy, and radiation, but functional medicine emphasizes prevention through diet, detoxification, stress management, and lifestyle changes.

Ductal Carcinoma In Situ (DCIS) is a noninvasive breast cancer, classified as stage 0. It accounts for about 20-25% of breast cancer cases and remains localized without spreading to other tissues. While conventional medicine considers DCIS a form of cancer, it does not typically metastasize. Detection often occurs through mammograms, which identify calcifications. Alternative diagnostic options include QT Imaging, CTC blood tests, and thermography. Conventional treatments like surgery and radiation may not always be necessary, as many DCIS cases do not progress to invasive cancer. Managing inflammation, supporting gut health, and maintaining a balanced diet can help mitigate risks.

Drinking green juice made from organic greens is a powerful way to support gut health and overall well-being. Packed with essential vitamins, minerals, and antioxidants, green juice helps reduce inflammation, boost the immune system, and improve digestion by making nutrients more bioavailable. One of the key benefits of drinking green juice is its ability to promote a healthy gut lining, which is essential for those struggling with leaky gut symptoms such as bloating, brain fog, and fatigue. Choosing Organic Greens ensures that you’re getting all the benefits without exposure to harmful pesticides or additives. Whether you make fresh juice at home or opt for a high-quality greens powder, incorporating green juice into your diet can be a simple and delicious way to nourish your body.

Glutathione, the body’s master detoxifier, plays a crucial role in eliminating toxins, boosting immune function, and promoting overall health. However, modern stressors like pollution, heavy metals, and synthetic chemicals deplete its levels, increasing the risk of chronic illness. While certain foods support glutathione production, supplementation is often necessary, especially for those with autoimmune conditions or toxin exposure. Supporting your glutathione levels can enhance detox pathways, reduce oxidative stress, and improve energy and immunity—making it a key component of a healthy lifestyle.
