Imagine seeing four doctors in three years and leaving every appointment with the same answer: your labs look “fine,” you’re probably just stressed, get more sleep. It wasn’t until she collapsed at work that anyone ordered the right test. She was 44. Her heart disease had been progressing for years, hiding in plain sight because her symptoms didn’t match the textbook. While this story is fictional, the pattern is not. It reflects the documented experiences of thousands of women across the United States and around the world whose symptoms are overlooked, dismissed, or misdiagnosed. Boston University’s newly published Women and Health study captures the scale of that pattern in a single, striking statistic: women in the U.S. live an average of five years longer than men, yet spend 25% more of their lives in poor health. Women are living longer than ever. But more years mean little if too many of them are spent in poor health. Longevity is not the finish line. A health system that stops at survival has not finished its job. Women deserve to thrive, not just endure.For decades, American medicine was built on a foundational assumption: that women’s bodies functioned essentially as men’s, with a few reproductive exceptions. Clinical trials typically excluded women. Drug dosages were calibrated to male physiology. Diagnostic criteria were drawn from data on male patients. This wasn’t born of malice but of incomplete science. Those research gaps shaped the treatments, protocols, and medical education that followed. Today we know better. Our responsibility is to practice medicine accordingly.
