Dr. Colbert explains why hypothyroidism (low thyroid function) is so common, especially among women, and how autoimmune issues like Hashimoto’s thyroiditis are linked to genetics and hormone fluctuations. You’ll also learn how environmental factors—including endocrine-disrupting chemicals (parabens, phthalates, PFAs)—and certain medications can interfere with thyroid health. Discover the early warning signs of low thyroid, from cold hands and chronic fatigue to eyebrow thinning, weight gain, hair changes, and swelling around the eyes. Dr. Colbert highlights the importance of testing the free T3 hormone (not just TSH and T4) to truly understand thyroid function and optimize energy, mood, and metabolism.
