Endometriosis and MS: What the Link Means for You Today
Key Takeaway
A review found that endometriosis and MS occur together more often than expected, but it does not show that either condition causes the other.
What They Found
Researchers reviewed 55 studies of endometriosis, a condition in which tissue similar to the lining of the uterus grows outside it. Five of those studies looked at its link with multiple sclerosis (MS). In studies that compared groups of women, MS was more common among those with endometriosis. Endometriosis was also linked with several other conditions, including long-lasting pain, severe tiredness, asthma, and bowel problems. The studies did not show a clear link with the thyroid problems they examined.
Who Should Care and Why
This review may be useful for people with MS who also have endometriosis or symptoms such as pelvic pain. Pain and tiredness can have more than one cause, so you do not have to assume every symptom comes from MS. Tell your care team about new or changing symptoms, including when they happen and how they affect your day. A symptom diary can help you describe patterns, much like a calendar helps you spot repeated events. Caregivers and healthcare providers can use that information to discuss whether a separate check for pelvic pain or other symptoms is needed.
Important Considerations
Most of the evidence was rated low or very low in quality, so the strength of the MS link is uncertain. These studies looked for patterns; they cannot show that endometriosis causes MS or that treating one condition will improve the other. Having endometriosis does not mean you will develop MS, and this review does not call for routine MS testing.

Whether you’ve recently been diagnosed with Multiple Sclerosis (MS) or are seeking to broaden your understanding of this complex, neurodegenerative disease, navigating the latest research can feel overwhelming. Studies published in respected medical journals like Autoimmunity reviews often range from early-stage, exploratory work to advanced clinical trials. These evidence-based findings help shape new disease-modifying therapies, guide symptom management techniques, and deepen our knowledge of MS progression.
However, not all research is created equal. Some clinical research studies may have smaller sample sizes, evolving methodologies, or limitations that warrant careful interpretation. For a more comprehensive, accurate understanding, we recommend reviewing the original source material—accessible via the More Details section above—and consulting with healthcare professionals who specialize in MS care.
By presenting a wide range of MS-focused studies—spanning cutting-edge treatments, emerging therapies, and established best practices—we aim to empower patients, caregivers, and clinicians to stay informed and make well-informed decisions when managing Multiple Sclerosis.
