Autoimmune conditions that coexist with endometriosis: when to test?

Some autoimmune conditions are reported more often alongside endometriosis, including autoimmune thyroid disease, celiac disease, rheumatoid arthritis, psoriasis, lupus, and Sjögren’s. This doesn’t mean endometriosis causes these conditions, but overlapping immune-driven inflammation can make symptoms blur together and delay clear answers.

Symptoms that commonly warrant a closer look include persistent fatigue out of proportion to sleep, heat or cold intolerance, hair thinning or loss, ongoing digestive symptoms (especially chronic diarrhea), joint pain with swelling or morning stiffness, rashes that worsen with sun exposure, dry eyes or dry mouth, and unexplained weight change. If these are part of your picture, our team can help you decide which labs are most appropriate—often starting with thyroid testing (TSH with thyroid antibodies), celiac screening (tTG-IgA with total IgA), and targeted inflammatory or antibody testing based on your symptoms—and coordinate next steps as part of a comprehensive evaluation.
