Gut health impacts thyroid function and hormone balance

Gut health may be linked to persistent thyroid symptoms like fatigue and weight gain, even with normal thyroid tests. The gut microbiome influences thyroid hormone conversion and absorption. Imbalances can lead to insufficient active thyroid hormone reaching tissues, causing symptoms despite adequate T4 levels. Chronic stress, inflammation, and nutrient absorption issues also impact thyroid function. Supporting gut health is considered part of a holistic approach to thyroid wellbeing.
