Unique national research for England has demonstrated the "significant" impact the gynaecological condition endometriosis has had on women's ability to earn and work.
Researchers suggest that following diagnosis, women may be taking lower-paid jobs or working fewer hours.
The charity Endometriosis UK called on workplaces to provide "support, understanding and reasonable adjustments for endometriosis" in order to "retain talented employees".
A government spokesperson said they were "committed to delivering the healthcare women need, when they need it, so that everyone can lead healthy, productive lives".
