A physician's guide to the hormones that shape your life.

The Book of Hormones by Shweta Patel MD — book cover

Finally, a Hormone Guide That Respects Your Intelligence

You've Googled your symptoms at 2 a.m. You've scrolled through conflicting Instagram advice. You've been told by a doctor that what you're feeling is "just stress" or "just aging."

The Book of Hormones is the resource I wish I could hand every patient on day one. It's a clear, medically accurate, and genuinely readable guide to how hormones shape your energy, mood, weight, sleep, libido, and aging — from your first period through menopause and the decades beyond.

No jargon. No fear-mongering. No oversimplified TikTok takes. Just the truth about your biology, written by a board-certified OB/GYN who's spent her career listening to women and helping them take control.
