A definitive and thorough handbook from the fun and personable Dr. Amie Hornaman (a.k.a. “The Thyroid Fixer”) that brings functional medicine and self-advocacy to the underdiagnosed epidemic of thyroid issues, particularly in women.

It’s not you; it’s your thyroid.

If you feel like there’s something wrong but you can’t get a doctor to listen, don’t have a diagnosis yet, or have a diagnosis and your treatment isn’t working, this book is for you. People—especially women—are consistently being dismissed and encouraged to accept symptoms that are anything but normal: weight gain that won’t budge, exhaustion that never lifts, hair loss, anxiety, brain fog, and mood swings.

Dr. Amie Hornaman is here to change that. The Thyroid Fix addresses what most doctors overlook: the real reason women feel fat, foggy, and fatigued isn’t laziness, aging, or a lack of willpower—it’s their thyroid. This book is a wake-up call—and a solution—for millions of women who are sick of feeling dismissed and misdiagnosed. It’s direct, real, and filled with strategies that actually work.

In this book, Dr. Hornaman teaches you what your lab results really mean, why “normal” ranges are often meaningless, and how to get treatment that actually works for your body. With authority and empathy, she invites you to bust myths, understand your labs, and finally get real answers. Readers will walk away with a self-assessment, facts, and questions to approach their doctors with, and solutions that range from conventional and functional medicine to prescriptions, supplements, and lifestyle shifts.

The Thyroid Fix is the straightforward, clinically-backed thyroid health guide you didn’t know you needed, but that might just change your life.
