Labs read "normal" but you're gaining midsection weight, foggy and running at 70%? Your thyroid - not just perimenopause - may be the missing variable. Dr. Amie Hornaman explains why TSH alone misses the picture, how elevated reverse T3 "pools" and blocks T3 at the cell even when free T3 looks optimal, and why roughly 98% of women don't thrive on T4-only. She links falling progesterone, rising thyroid-binding globulin, low ferritin and the "thyropause" hitting 80-90% of women over 40. WHAT YOU'LL LEARN Why a "normal" TSH can completely miss a thyroid problem - and the five markers that actually reveal what's happening What reverse T3 "pooling" is, and how it blocks active thyroid hormone at the cell even when your free T3 looks optimal Why roughly 98% of women stop thriving on T4-only medication once they're past 40 How falling progesterone drives estrogen dominance, raises thyroid binding globulin, and quietly strands thyroid hormone before it reaches the cell What "thyropause" is, why it hits 80-90% of women over 40, and how it overlaps with the perimenopause symptoms you're blaming instead Why testosterone acts as armor against autoimmunity - and what its decline switches on…
