Thyroid Truths, GLP-1s, and Why Women Are Still Being Gaslit with McCall McPherson

In this episode of The Healthspan Collective, host Nicole Doran sits down with integrative thyroid expert McCall McPherson, founder of Modern Thyroid Clinic, for a conversation on thyroid dysfunction, women’s health, and why so many women are still being told their labs are “normal” while continuing to feel unwell.
McCall shares her own experience struggling with debilitating hypothyroid symptoms despite being prescribed standard thyroid medication, and how that journey ultimately led her to specialize in thyroid care. Together, Nicole and McCall unpack the limitations of conventional thyroid testing, including why relying on TSH alone can leave many women undiagnosed or improperly treated.
The conversation explores the importance of full thyroid panels, the role of T3-containing medications, and the symptoms that are often overlooked or dismissed, from low libido and dry skin to puffiness, fatigue, thinning eyebrows, and inability to sweat. They also discuss Hashimoto’s disease, thyroid autoimmunity, and the growing links between COVID, long COVID, and thyroid dysfunction.
Nicole and McCall also get into fertility, miscarriage prevention, postpartum thyroid shifts, menopause, hormone replacement therapy, and the nuanced conversation around GLP-1s. McCall explains her approach to microdosing GLP-1 medications for inflammation, metabolic dysfunction, and weight management, while emphasizing patient safety and individualized care.
This episode is a deeper look at the intersection of thyroid health, hormones, metabolism, and advocacy, especially for women who know something feels off despite being told everything looks “fine.”
