Why do people with endometriosis often have other conditions?

It’s common for endometriosis to show up alongside other diagnoses because endometriosis isn’t a single, uniform disease—it's a complex, multifactorial condition with different subtypes and drivers. In many patients, the same underlying biology (genetics/epigenetics, inflammatory signaling, and immune-system dysfunction) that allows endometriosis to implant and persist may also make the body more prone to other inflammation-related or immune-associated conditions. On top of that, endometriosis can involve multiple organs (bladder, bowel, pelvic nerves, and beyond), so symptoms may reflect more than one process happening at the same time.

There’s also a practical reason this overlap gets missed at first: many gynecologic conditions share symptoms. Endometriosis and adenomyosis can both cause pelvic pain, painful periods, pain with sex, bloating, and bowel/bladder symptoms, while conditions like fibroids or polyps can add heavy bleeding, clots, anemia, or pressure—so a single label may not explain the whole picture. In our practice, we intentionally evaluate for coexisting conditions because identifying the “full stack” of what’s driving your symptoms often changes the treatment plan and helps us tailor surgery and whole-person care more effectively. If your symptoms feel broader than endometriosis alone—or they haven’t improved the way you expected—reach out to our team to discuss a comprehensive evaluation.
