Endometriosis
A brain-based perspective
Chronic inflammation
Endometriosis is a chronic inflammatory condition where tissue similar to the uterine lining grows outside the uterus - usually in the pelvis, but sometimes beyond. These growths can cause pain, fatigue, and fertility challenges. It's now understood endometriosis affects not only the body, but also how the brain processes pain.
Highly prevalent
Endometriosis affects an estimated 1 in 10 women and people with periods -yet many go undiagnosed for years. Symptoms often begin in adolescence but are frequently dismissed or misunderstood, leading to an average delay of 7-10 years before diagnosis.
Range of treatment options
Diagnosis often involves pelvic exams, imaging, or laparoscopic surgery - though non-invasive methods are improving. Treatment options include hormonal therapies, pain management, and surgery. More recently, brain-based approaches that target the nervous system’s role in chronic pain are also being used.
