In this episode of the Vibrant Wellness Podcast, Dr. Philip Oubre sits down with McCall McPherson, PA-C, founder of Modern Thyroid Clinic, to explore why thyroid conditions are so often misdiagnosed or dismissed. McPherson shares her personal journey from being a symptomatic patient told her labs were “normal” to becoming a leading thyroid specialist. The conversation highlights how many patients fall through the cracks when care relies too heavily on limited testing and outdated guidelines.
During the conversation, McPherson breaks down the key symptoms of thyroid dysfunction and why so many are overlooked or attributed to stress, aging, or unrelated conditions. She explains why TSH-only testing misses critical issues and outlines the full panel patients should request, including free T3, free T4, reverse T3, and thyroid antibodies. She also discusses how lifestyle factors like stress, under-eating, and inflammation can disrupt thyroid hormone conversion, leaving patients symptomatic even when labs appear “normal.”
The discussion also covers treatment approaches, including the differences between T3 and T4 medications, common myths that make clinicians hesitant to use certain therapies, and the importance of proper lab timing for accurate results. McPherson also addresses Hashimoto’s and autoimmune thyroid disease, emphasizing that antibodies can often be improved through targeted lifestyle and clinical interventions. This week's episode reinforces that with comprehensive testing and personalized care, patients can move beyond symptom management and regain their energy, metabolism, and overall quality of life.
