Doctors Now Have Different Opinions of What Endometriosis Really Is


Traditionally, it’s been believed that endometriosis is a disease where uterine tissue grows outside the uterus and attaches to nearby tissue and organs, creating painful lesions and inflammation.

However, according to a recent article on, some medical professionals believe that the tissue isn’t actually uterine tissue but cells that are similar to uterine cells. These copycat cells are able to produce estrogen and should be shed the same way as uterine cells, i.e., during monthly menstruation.

While doctors may disagree on the type of cells causing the issue for women living with the condition, they do agree that it’s the cells not leaving the body each month that causes the problem.

Another issue dividing researchers is whether endometriosis is caused by retrograde menstruation — where instead of the blood and unwanted tissue leaving the body, it flows back into the fallopian tubes and into the pelvic area.

Some experts believe that many women suffer from retrograde menstruation (up to 90 percent), so why would only 10 percent of women have endometriosis? This school of thought believes women are born with the disease and will only begin showing symptoms once they begin their periods, as these women’s immune systems are not as well equipped to deal with clearing up debris from retrograde menstruation.

    What good is it for women to discuss Endometriosis if providers are not willing to consider Endometriosis as the underlying problem to begin with. Even if the diagnosis has been confirmed, most individuals are told that they are suffering from Depression or Fibromyalgia and that Endometriosis is just secondary to any symptoms that they may be experiencing.The constant abuse that a woman’s body must endure from having endometriosis actually causes the body to slowly break down over time. The immune system is in a constant state of hypervigilance there by causing chronic inflammation that causes chronic pain. Eventually, a woman will discover that they have an autoimmune disease because the immune system was never able to rest. Our bodies will react the same to foreign substances in the same manner. That’s what Endometriosis is, a foreign substance!
