Women’s health has been neglected because modern medicine was largely built on male bodies, male symptoms, and male research subjects. For decades, women were actively excluded from clinical trials, medical textbooks treated male anatomy as the default, and conditions that disproportionately affect women received less funding and attention. The consequences are measurable: longer diagnostic delays, higher misdiagnosis rates, and worse outcomes for conditions ranging from heart disease to chronic pain.
Women Were Excluded From Clinical Trials for Decades
In 1977, the FDA recommended excluding women of childbearing potential from early-phase drug trials. The policy was a reaction to the thalidomide tragedy, in which thousands of women across Europe and Canada who took the sedative during pregnancy gave birth to babies with severe limb deformities. Researchers adopted what they considered a cautious approach, but the effect was sweeping: for the next 16 years, drugs were developed and tested primarily on men, then prescribed to women with little understanding of how female biology might alter their effects.
It wasn’t until 1993 that Congress passed the NIH Revitalization Act, which wrote the inclusion of women and minorities into federal law for NIH-funded clinical research. That means an entire generation of medical knowledge, from drug dosing to disease progression models, was built on data that systematically excluded half the population. Many medications still in use today were approved based on those earlier, male-dominated trials.
Medical Education Treats Male as Default
The problem goes deeper than clinical trials. Medical schools have historically taught female biology almost exclusively through the lens of reproduction, while treating everything else (cardiology, neurology, pain response) as though sex differences don’t exist. A survey of U.S. medical schools found that only 14% had implemented a women’s health curriculum, and just 10% had a program responsible for integrating sex-specific information across the curriculum. By 2004, only 30% of medical schools listed sex- or gender-specific topics in their curricula.
This means most physicians trained in the last few decades learned to recognize diseases based on how they present in men. When women show up with different symptoms, those symptoms are more likely to be dismissed, misread, or attributed to psychological causes.
Heart Disease: The Clearest Example of Misdiagnosis
Heart disease is the leading killer of women in the United States, yet women are 50% more likely than men to be misdiagnosed when having a heart attack. The reason is straightforward: the “classic” heart attack presentation, crushing chest pain radiating down the left arm, is the classic male presentation. Women more often experience nausea, back and neck pain, shortness of breath, fatigue, indigestion, and palpitations. Some women have no chest discomfort at all.
Because these symptoms don’t match the textbook picture doctors were trained on, they’re frequently misdiagnosed as gastrointestinal problems or anxiety. This isn’t a fringe finding. Multiple systematic reviews have documented physicians attributing women’s cardiac symptoms to mental health conditions, leading to delayed treatment during a window when minutes matter.
Women’s Pain Is Taken Less Seriously
Women experience chronic pain conditions at higher rates than men, including migraines, fibromyalgia, and autoimmune-related pain. Despite this higher prevalence, research consistently shows that women’s pain is taken less seriously, faces greater diagnostic delay, and is more likely to be undertreated compared to men reporting similar symptoms. Even for pain that signals serious conditions like heart disease, missed or delayed diagnoses are more common in women.
This pattern has roots in a long medical tradition of attributing women’s physical complaints to emotional or psychological causes. The word “hysteria” itself derives from the Greek word for uterus. While the diagnosis is no longer used, the underlying bias persists in subtler forms: women reporting pain are more likely to receive referrals for psychiatric evaluation, while men with the same complaints are more likely to receive diagnostic workups for physical causes.
Conditions Affecting Women Face Long Diagnostic Delays
Endometriosis affects roughly 10% of women of reproductive age worldwide, yet the average time from first symptoms to diagnosis is between 4 and 12 years, according to the World Health Organization. That’s up to a decade of debilitating pain, heavy bleeding, and fatigue before a woman receives a name for what’s happening to her, let alone treatment.
Autoimmune diseases tell a similar story. Four out of every five people diagnosed with an autoimmune condition are female. Despite this overwhelming skew, these diseases are notoriously difficult to diagnose, often requiring visits to multiple specialists over several years. The early symptoms, fatigue, joint pain, brain fog, tend to be vague enough that they’re easy to dismiss, and many women report being told their symptoms are stress-related before eventually receiving a diagnosis.
Maternal Health Gaps in the United States
The U.S. has the highest maternal mortality rate among wealthy nations, and the numbers reveal stark racial disparities. Provisional CDC data for the 12-month period ending September 2025 puts the overall maternal mortality rate at 16.7 deaths per 100,000 live births. For white, non-Hispanic women, the rate is 13.8. For Black, non-Hispanic women, it’s 43.3, more than three times higher.
These deaths are not inevitable. The CDC has estimated that roughly 80% of pregnancy-related deaths are preventable. The gap reflects systemic failures: inadequate postpartum follow-up, dismissal of Black women’s reported symptoms, lack of access to quality maternal care in many communities, and chronic conditions that go unmanaged before and during pregnancy. Maternal health is perhaps the most direct expression of what neglect looks like when it becomes a body count.
The Economic Cost of the Gap
Neglecting women’s health isn’t just a medical failure. It’s an economic one. A joint report from the World Economic Forum and McKinsey Health Institute estimated that closing the women’s health gap could add $1 trillion to the global economy annually by 2040. That figure reflects the productivity lost when women spend years managing undiagnosed or undertreated conditions, miss work due to symptoms that could have been addressed earlier, or leave the workforce entirely because the healthcare system failed to keep them healthy.
The investment needed to close this gap is a fraction of that return. Better diagnostic tools for female-pattern heart disease, faster pathways to endometriosis diagnosis, inclusion of sex-specific data in drug development, and training physicians to recognize how diseases present differently in women are all achievable steps. The barriers are not scientific. They are institutional, rooted in decades of treating women’s bodies as variations on a male norm rather than as distinct biological systems that deserve equal rigor.
