Episode Details

What if the most dangerous metabolic inflection point in a woman's entire life is the one we've been taught to simply endure?

In this episode of Health Longevity Secrets, Robert Lufkin MD sits down with Dr. Mayoni Gooneratne — a London-trained former NHS colorectal and pelvic floor surgeon, now the founder of Human Health and vice-chair of the British College of Functional Medicine. Dr. Mayoni walks us through why she walked away from the operating theater and how perimenopause — not menopause — is the real window where metabolic disease, cognitive decline, and cardiovascular risk are either quietly programmed in or actively reversed.
