Symptoms Originally Attributed to Thyroid Dysfunction Were Instead Caused by Suboptimal Gastrointestinal Health: A Case Series and Literature Review.

The integrative and functional medicine field has drifted towards a thyroid-centric approach of care (fine-tune thyroid medication, support thyroid hormone conversion, and improve thyroid levels). However, many patients still do not improve symptomatically. Here, we show how a gut-focused clinical care model can improve thyroid function, reduce thyroid medication dose, and improve symptoms originally thought to be from thyroid dysfunction. We present a literature review on the gutthyroid axis and then document clinical application of this evidence through six case reports of how patients improved thyroid function and thyroid-related symptoms by improving their gastrointestinal health. Clinicians will likely experience better patient outcomes by integrating the contents of this paper into their practice.
