We love Lena Dunham because she's never been shy about her body. She deliberately flaunts her not-exactly-size-2 body onscreen. This confidence, paired with the fact that she speaks so candidly about her body image issues, is what's made her such a prominent leader of the body-positive movement for years now.
But her refreshing candor extends far beyond tweeting about her "issues with underpants," as she put it. She is also very open about her struggle with endometriosis, an often painful chronic condition in which tissue that normally lines the inside of your uterus grows outside your uterus.
Dunham posted on Instagram that her endometriosis has caused her to take a break from promoting the up-and-coming fifth season of Girls.
