Is your period pain unbearable? You could suffer from endometriosis, an incurable disease which remains largely unknown
- As many as one in 10 women worldwide suffer from endometriosis, a chronic disease associated with their periods
- In recent years, celebrities including model Chrissy Teigen and actress Lena Dunham have used social media to share their own diagnoses

Lorena Garcia was in her 20s when she was suddenly struck with crippling pain associated with her menstrual cycles.
It was four years before she was diagnosed with endometriosis, a chronic, incurable disease that affects as many as one in 10 women worldwide.
Before the diagnosis, she recalls feeling fearful and powerless as she sought help from over a dozen doctors, most of whom would tell her the pain was normal.
“It was hell,” the Barcelona resident, now in her 30s, said. “The doctors who look down on you, who call you crazy or even say that you’re hysterical … I felt very alone.”

Endometriosis occurs when the cells that normally line the inside of the uterus migrate and grow in other parts of the body, mostly the pelvic organs – including the vagina, cervix and uterus – but also the bowel and bladder.
