Explaining Endometriosis (5:26)

When women experience abdominal or pelvic pain, they often write it off as menstrual cramps. While cramps are certainly common, another lingering and often more painful condition called endometriosis that palgues millions of women can also be the culprit.

 

What is Endometriosis?

Endometriosis is a disease where cells normally found in a woman's uterus end up in other areas of the body, where they can cause inflammation, damage to and scarring in tissues in the surrounding area. That inflammation and damage can then lead to the symptoms like pain, infertility, bowel or bladder issues.

 

What Causes Endometriosis?

The uterus is made up of different layers, including several layers of muscle and an inner layer of cells called the endometrium. The endometrium is the part of the uterus that is full of blood vessels and that nourishes a growing fetus when a woman becomes pregnant. It's also the layer that gets replaced every month during a woman's period. The bleeding a woman experiences each month is the unused endometrium leaving the uterus.

For reasons that still aren't clear, sometimes cells from this endometrium layer end up in places outside of the uterus. While the cells aren't in the right place anymore, they still act in the same way they would in the uterus. That means that monthly hormone signals from the body still cause them to grow over the course of the month and then die and bleed at the end of the month. But unlike in the uterus, there's nowhere for the blood and dead cells to go. Instead, the gather at the center of this ball of endometrial cells, which can swell, become inflamed and irritate surrounding tissues causing pain, scarring and other problems.
