Maybe you’ve noticed you don’t feel like yourself anymore. The brain fog, mood swings, weight gain and exhaustion creep in slowly, and most women never realize these symptoms can start as early as their late 30s. Too often, they’re dismissed as stress, depression, or just part of getting older. But they’re not, they’re signs of perimenopause.
Dr. Mary Claire Haver, leading OB/GYN, bestselling author of The New Menopause and the upcoming book The New Perimenopause, joins me to explain what’s really happening in this overlooked stage of life and why it matters for every woman’s long-term health.
They talk about:
- Why so many women miss the early signs of perimenopause
- The science behind hormonal chaos and how it impacts your brain, heart, bones, and metabolism
- The real cost of being told to “tough it out,” from osteoporosis to dementia
- Which symptoms to watch for (beyond hot flashes) and why blood tests often don’t give answers
- The tools and mindset shifts that help you feel like yourself again
If you’ve ever felt “off” and wondered if it’s you, stress, or something deeper, this conversation will give you answers, validation, and a way forward.
