I. A Number, and Everything Beyond the Number
Eighty percent. This is the percentage of women among those suffering from autoimmune diseases. A number that has remained stable for decades, a statistic that has been repeatedly cited, a number that sounds alarming enough, yet fails to truly convey its meaning.
Because the real question isn’t “how many,” but “what does it mean.”
These diseases—rheumatoid arthritis, lupus, multiple sclerosis, Hashimoto’s thyroiditis, and over seventy other known diseases—are typically diagnosed during a woman’s most active age: from early adulthood to middle age. That’s when careers are taking shape, family responsibilities begin to accumulate, and social life is at its most intensive. It’s also a time when a person begins to define who they are and what they want.
And the disease intervenes at that moment, rewriting everything.
II. The Cost of Work
In 2026, the Autoimmune Association and WellTheory conducted a nationwide survey of working women with autoimmune diseases.
Seventy percent said their career potential was impaired as a result.
Sixty-eight percent of respondents reported significant negative career impacts. Of these, 28 percent were forced to take lower-demand roles, 14 percent had to change careers, and 13 percent turned down promotions. Thirty-nine percent reduced their working hours, and 11 percent left the workforce altogether.
The reasons are not complicated: pain (61%), fatigue (54%), and brain fog (26%). These symptoms won’t appear on resumes or be mentioned in meetings, yet they erode a person’s work ability day after day.
More notably, 61 percent of women did not disclose their diagnosis to their employers. They felt it was pointless (41%), feared judgment (31%), and worried about missing opportunities (28%). They chose silence not because their illness wasn’t serious, but because the system didn’t give them a voice.
III. Bills and Invisible Debts
Jay Bhattacharya, director of the National Institutes of Health, stated that autoimmune diseases cost the U.S. healthcare system over $100 billion annually in direct costs. This figure would be even higher if lost productivity and indirect impacts on families and society were included.
For individuals, additional medical and pharmacy costs range from $2,200 to $33,500 annually. This is despite women earning less than 15 percent of what men do.
But money is only one type of debt. More insidious is the debt of time—those afternoons spent in waiting rooms, those plans canceled due to sudden attacks, those promises made because of the uncertainty of tomorrow.
IV. Family and Social Life: The Unquantifiable Aspects
Research attempts to capture the impact of illness on family and social life. Results show increased caregiving burdens, greater relationship stress, and decreased social engagement. Driving these changes are fatigue, pain, and the uncertainty of attack cycles.
Up to half of patients with autoimmune diseases report a decline in quality of life. Women are not only more susceptible to illness but also more prone to depression.
Patient advocate Amy Kurtz, in her forthcoming book But You Look Fine, says that data only captures the tip of the iceberg. “If you have a latent disease, your entire life will be altered in countless ways. Your childhood dreams of your life—career, family, everything—could be thrown out the window. No matter the severity, your entire life plan begins to change.”
V. Why Them? Three Emerging Explanations
X Chromosome
In 2024, researchers at Stanford University School of Medicine published a finding in the journal Cell: the X chromosome plays an active role in the development of autoimmune diseases—or rather, a “not completely silenced” role.
Women carry two X chromosomes, one of which should be “turned off” to prevent overexpression of genes. However, research has found that this shutdown is not always complete. An incompletely silenced X chromosome can lead to an overactive immune system.
But this doesn’t explain everything. If the X chromosome were the only cause, men wouldn’t be affected. The fact is, they are.
Lifestyle and Environment
Integrative medicine physician Dana Cohen points out that while genetics clearly plays a role, most researchers now estimate that environmental factors account for 70% or more of the risk of autoimmune diseases. “The environment I’m referring to is broad—diet, gut microbiome health, chronic stress, sleep quality, toxic exposures such as endocrine disruptors, and physical activity. These aren’t just lifestyle factors; they’re signals telling your genes what to do.”
Chronic stress can damage the immune system and trigger inflammation. While both sexes experience psychological stress, research shows that stress affects the brain differently—testosterone may buffer the negative effects of stress on mental health. And some of the stressors women face in their daily lives are things men often don’t experience. Data from the American Psychological Association shows that women consistently report higher levels of daily stress than men, and the link between chronic stress, inflammation, and immune dysregulation has long been established.
Hormones
Estrogen, progesterone, and androgens all interact with the immune system. Estrogen, in particular, tends to enhance immune activity. This is often seen as an evolutionary advantage for women—studies show that women’s immune systems are more effective, especially during pregnancy and postpartum.
But this can also increase susceptibility to autoimmune diseases. Many autoimmune diseases, such as multiple sclerosis and lupus, are estrogen-driven.
VI. Diagnosis: Lost in the Gray Area
On average, it takes nearly five years to receive a diagnosis of an autoimmune disease. Five years without answers, five years being dismissed as “too much stress” or “overthinking,” five years wandering in the gray areas of a black-and-white medical system.
Kurtz says this can feel like being “lost in a no-man’s-land.” You’re constantly denied, brushed off, and told it might all be your imagination. Over time, you begin to doubt your feelings, your memories, and your reason.
The medical “gaslighting effect”—the systemic disregard for patient symptoms by the medical system—has been proven to lead to delayed diagnosis, ignored symptoms, patient self-doubt, and even questioning of one’s mental state.
Kurtz calls this “a breakdown of trust in the body.” When you no longer trust your body’s signals, you lose your most basic navigational tool.
VII. Becoming Your Own Advocate: A Forced Selfishness
“Women are taught to put others’ needs above their own. Selflessness is considered a virtue. But a health crisis requires you to put on an oxygen mask first—just to feel a little better,” Kurtz says.
In an ideal healthcare system, women would receive the care, respect, and support they need. But reality is different. For most women, navigating diagnosis and treatment is a solitary battle.
So, what should an “empowered patient” look like?
Document symptoms, carry a list of questions, establish direct communication channels for follow-up, and request copies of lab results and medical records. Seek a second opinion when you feel unwell. Build a care team that focuses not just on a single organ system, but on overall health.
“Being a patient in the healthcare system, especially as a woman, can be incredibly disheartening. And if you want to get better, it’s up to you,” Kurtz says. “Promise yourself: ‘I will do everything I can to only have people who respect me treat me.’ It’s entirely up to you.”
She cautions against subtle warning signs: feeling rushed, almost no eye contact, lack of empathy, defensiveness, or immediately jumping to an “anxious” diagnosis without sufficient consideration. These may be signs you haven’t found the right partners. “If someone treats you badly, don’t hesitate to leave and keep looking.”
VIII. What Needs to Change
Closing the Diagnostic Gap
Autoimmune diseases are already difficult to diagnose, and gender bias exacerbates the problem. Many women spend years seeking a diagnosis only to be told their symptoms are related to stress. Symptoms like fatigue and pain are more easily overlooked in women, delaying treatment.
Women-Centered Research
Historically, women have been underrepresented in clinical research. Groups like the Office of Women’s Health Research at the National Institutes of Health are working to change this, but the gap persists.
Making Integrative Medicine the Standard
Nutrition, stress management, sleep, and gut health are consistently linked to outcomes in autoimmune diseases. Yet, these are often seen as “complementary” rather than “fundamental.” This needs to change.
Environmental Policy
If environmental triggers are part of the equation, prevention must extend beyond the clinic. Regulation surrounding chemical exposure and pollutants is increasingly becoming part of the autoimmune disease discussion.
Autoimmune diseases are redefining women’s lives—their career paths, family structures, finances, and long-term well-being. Science is advancing, our understanding of biological drivers is deepening, from X chromosome activity to hormonal changes, and more advanced therapies are emerging on the horizon.
But for most women living with these diseases today, reality remains defined by delayed diagnosis, fragmented care, and the struggle to be believed. This is the real crisis.
Progress requires more than just medical breakthroughs. It requires earlier detection, more inclusive research, better models of care, and a system that takes women’s symptoms seriously the moment they first speak. It also needs to recognize that autoimmune diseases are not just a collection of illnesses—but a public health problem with far-reaching social and economic consequences.
Until then, women will continue to bear this burden. Often unseen.
