Lena Dunham is in the hospital and set for surgery after suffering complications from endometriosis, reports People. "This morning, she suffered from an ovarian cyst rupture and has been taken to the hospital," a rep says in a statement, adding that the Girls star "will be undergoing surgery at an undisclosed hospital." Dunham announced last month that she would be taking a break due to the "chronic condition," which USA Today notes is "a disorder in which tissue normally found in the uterus grows outside that organ," and causes cramping, irregular periods, and infertility. "I am currently going through a rough patch with the illness and my body (along with my amazing doctors) let me know, in no uncertain terms, that it's time to rest," Dunham said in her post last month.
