As my ever-creative title suggests, March is Endometriosis Awareness Month. I have endometriosis (“endo” for short), and I like this month because I know plenty of people in my life who could definitely use some more awareness as to what endometriosis is and how it impacts the lives of those who have it.

So what is endometriosis, anyway?

Endometriosis is a condition where the endometrium, the lining of the uterus, grows outside the uterus — often on the ovaries, bladder, bowel, and/or lining of the pelvic area. This can be a problem for two reasons. One is that during menstruation, there’s nowhere for this “rogue endometrium” (not a technical term) to go, not having a way to the cervix and vagina and all. This can cause pain — most often pain during menstruation — as well as a buildup of tissue that remains throughout subsequent cycles, where even more “rogue endometrium” is added to it. The other is that the endometrial lesions can contribute to infertility, particularly if the endo obstructs the ovaries or fallopian tubes.

That doesn’t sound like fun. Is endometriosis rare?

Surprisingly, no. Exact numbers are hard to come by because a lot of cases are thought to go undiagnosed (which is part of the reason for this whole “awareness month” thing). But the estimate is that endo affects just over 10 percent of people with ovaries during their reproductive years — and about 30 to 50 percent of such people who have problems with infertility or pelvic pain. Odds are pretty good that you personally know someone with endometriosis, even if you don’t (or they don’t!) know they have it. Continue reading →
