Women battling endometriosis are losing the equivalent of a full month’s pay every year, according to new research out of Hungary.
Story Snapshot
- A 2026 Hungarian study found affected women lose about €1,757 a year in income, close to one month’s average salary there.
- Britain’s Office for National Statistics found monthly earnings drop significantly for years after diagnosis.
- A U.S. cohort study found lower annual salaries and slower salary growth in women with endometriosis compared to peers.
- Global research shows the condition eats up more than 10 hours of weekly work time through reduced effectiveness on the job.
A Chronic Illness With A Real Price Tag
Endometriosis is a painful condition where tissue similar to the uterine lining grows outside the uterus. It affects roughly one in ten women of reproductive age worldwide. For decades, doctors have documented the physical toll. Now researchers are putting a dollar figure, or in this case a euro figure, on the financial damage it does to a woman’s paycheck.
The Hungarian study is the sharpest data point yet. Researchers tracked work hours among women with the condition and found they missed nearly twice as many hours over a four-week stretch compared to unaffected peers. That gap translated into an estimated €1,757 in lost income per year, a number researchers say lines up closely with one month’s average salary in Hungary.
That single number captured headlines, but it is not an isolated finding. It fits a pattern researchers have been building for years across multiple countries, using different methods, yet arriving at the same basic conclusion: endometriosis quietly drains money out of women’s bank accounts long after the diagnosis is made.
Britain’s Payroll Data Tells The Same Story
England’s Office for National Statistics linked actual diagnosis records to payroll data covering 2016 through 2022. The results showed a statistically significant drop in monthly earnings among women ages 25 to 54 after diagnosis. Four to five years out, average monthly pay fell by £130 across all women studied, and by £56 among those still working.
The British data also revealed something the Hungarian euro figure cannot capture alone. Women with endometriosis became less likely to hold paid employment at all after diagnosis. That means the wage-loss numbers likely understate the real damage, since women who leave the workforce entirely simply disappear from paycheck calculations.
Across the Atlantic, a separate longitudinal study matched American women with endometriosis against similar women without it. Every single year for five years after diagnosis, the endometriosis group earned significantly less. Their salaries also grew more slowly, and they faced higher odds of losing work altogether, whether through reduced hours, job changes, or leaving the labor force.
Lost Hours Add Up Even When Women Show Up
Not every dollar lost comes from missed shifts. Much of it comes from what researchers call presenteeism, showing up to work while too sick or in too much pain to function at full capacity. One study found women with endometriosis lost 5.3 hours a week to presenteeism, compared to just 1.1 hours to outright absenteeism.
A broader multicountry analysis found the toll runs even deeper globally. Affected women lost an average of 10.8 hours of work per week, mostly from reduced effectiveness rather than missed days. Monetized losses varied sharply by country, from a few dollars a week in Nigeria to hundreds of dollars a week in Italy, reflecting how local wages shape the true financial hit.
Why The Numbers Won’t Match Everywhere
No single figure applies worldwide, and researchers are upfront about that. Hungary’s €1,757 estimate depends on Hungarian wages. Britain’s £130 monthly drop reflects British pay scales and benefit systems. A woman’s actual loss depends on her country’s average salary, her job’s flexibility, and how generous her sick leave protections are.
What stays consistent across every study, regardless of country or method, is the direction of the effect. Endometriosis costs working women money, whether measured in missed hours, slower raises, reduced employment odds, or straight-up smaller paychecks. That consistency across independent datasets in Hungary, England, and the United States is what makes the pattern hard to dismiss as a fluke of one study or one country’s economy.
What Comes Next For Employers And Policymakers
Researchers are calling for better workplace accommodations, faster diagnosis, and more flexible sick leave for women managing chronic pain conditions. Some have proposed linking national payroll records to diagnosis dates in more countries, following the British model, to see whether the earnings decline holds up outside Europe and North America.
Until then, the burden falls on individual women navigating pain, missed promotions, and shrinking paychecks largely on their own. The data now makes clear this isn’t just a health issue tucked away in a doctor’s office. It’s a financial issue playing out in bank accounts and paychecks across multiple continents.
For millions of working women, that means the cost of a chronic illness isn’t measured only in pain scales and hospital visits. It shows up on a pay stub, year after year.
