Five Theories on Endometriosis: What Causes This Common Women's Health Issue?

Millions of women worldwide suffer from endometriosis, a condition where tissue similar to the uterine lining grows outside the uterus. Recent research suggests multiple factors might contribute to its development. Dr. Sooj, MBBS BSc MRCGP, a board-certified family medicine physician, highlights five key theories. He explains retrograde menstruation, where menstrual blood flows back through the fallopian tubes, as a potential cause. He also notes a genetic predisposition, although no specific gene has been identified. Environmental toxins, specifically dioxins, have also been linked to endometriosis in animal studies. Stem cells, which can develop into endometrial-like cells, are another factor. Finally, Dr. Sooj clarifies that the combined contraceptive pill doesn't necessarily make endometriosis worse due to the progesterone balance. "The relationship between estrogen and endometriosis is complex," explains Dr. Sooj. "The absence of estrogen doesn't guarantee the absence of endometriosis." This informative overview helps increase awareness and understanding of this prevalent condition.
