Is Endometriosis An Autoimmune Disorder?


Endometriosis is a condition characterized by the growth of endometrial-like tissue outside the uterus, causing pain, inflammation, and other distressing symptoms.

While traditionally considered a gynecological disorder, emerging evidence suggests that endometriosis may also involve autoimmune mechanisms.


Here, we will explore the intriguing link between endometriosis and autoimmunity, shedding light on the potential autoimmune aspects of this condition.



  • Understanding Autoimmunity: Autoimmune disorders occur when the immune system mistakenly attacks the body's own tissues, perceiving them as foreign invaders. This immune dysregulation leads to chronic inflammation and tissue damage. Common autoimmune disorders include rheumatoid arthritis, lupus, and multiple sclerosis.

  • Immune Dysfunction in Endometriosis: Studies have revealed immune system abnormalities in individuals with endometriosis, suggesting an autoimmune component. Dysregulated immune responses, such as altered levels of certain immune cells, increased inflammatory markers, and abnormal immune function, have been observed in endometriosis patients. These immune system disturbances contribute to the chronic inflammation and tissue damage characteristic of the condition.

  • Autoantibodies and Endometriosis: Autoantibodies are immune molecules that mistakenly target the body's own tissues. In endometriosis, researchers have identified the presence of autoantibodies that target specific endometrial proteins. These autoantibodies may further contribute to the immune response and tissue inflammation seen in the condition.

  • Genetic Factors: Both autoimmune disorders and endometriosis have genetic components. Several genes associated with autoimmune diseases have been found to be involved in endometriosis development as well. This suggests a shared genetic predisposition or overlapping molecular pathways between autoimmunity and endometriosis.

  • Impact of Inflammation: Inflammation plays a significant role in both autoimmune disorders and endometriosis. In endometriosis, inflammatory responses are triggered by the presence of ectopic endometrial tissue, resulting in pain, tissue scarring, and infertility. The persistent inflammation in endometriosis may contribute to the immune dysregulation observed in autoimmune conditions.

  • Shared Symptoms and Comorbidities: Endometriosis and autoimmune disorders often share symptoms and comorbidities. Fatigue, chronic pain, and hormonal imbalances are common in both conditions. Additionally, individuals with endometriosis have a higher prevalence of autoimmune diseases, indicating a potential underlying connection.


While further research is needed to fully understand the complex relationship between endometriosis and autoimmunity, growing evidence suggests an autoimmune component in the development and progression of endometriosis.


The immune system dysfunction, presence of autoantibodies, genetic factors, and shared symptoms provide intriguing insights into the potential autoimmune aspects of this condition.


Recognising the potential autoimmune nature of endometriosis can help inform treatment approaches. A comprehensive approach that addresses immune dysregulation, inflammation, and hormonal imbalances may be beneficial for managing the symptoms and improving the quality of life for individuals with endometriosis.


It is important for individuals with endometriosis to work closely with healthcare professionals who understand the complexity of the condition and its potential autoimmune aspects. By advancing our knowledge and exploring the intersection of endometriosis and autoimmunity, we can uncover new avenues for effective management and support those affected by this challenging condition.
