S1E22 The Menopause Gut Connection: Why Hormones Alone Aren't Enough with Cynthia Thurlow

In this episode of 40s Forward, Dr. Betsy Greenleaf sits down with Cynthia Thurlow, nurse practitioner, two-time TEDx speaker, bestselling author, and internationally recognized expert in perimenopause, menopause, and women's metabolic health.

While hormones play a critical role in helping women navigate midlife, Cynthia explains why hormone replacement therapy is only part of the solution. Drawing from both personal experience and decades of clinical practice, she shares why the gut microbiome may be one of the most overlooked factors affecting energy, weight, mood, inflammation, immunity, and overall health during perimenopause and menopause.

Her new book, The Menopause Gut Balance, explores how changes in estrogen, progesterone, and testosterone impact the gut and why supporting the microbiome is essential for thriving in midlife and beyond.
