One of the most dangerous things a woman can do in much of the world is become pregnant, and the risks caught up with a Kenyan named Alice Wanjiru a decade ago.

Then 20 years old and pregnant for the first time, she suffered a childbirth injury called an obstetric fistula, caused by prolonged labor without access to a C-section to end it. This left her with a hole in the tissue between her rectum and her vagina, and for 10 years she endured the humiliation of continually leaking stool through her genital tract.

“I could never get fully clean, for there was always some stool left,” she told me. “The other women would say, ‘She is the woman who stinks.’ I would ask God, ‘Why me? Why can’t I be like other women?’”

Wanjiru bathed herself several times a day, fasted from morning until evening so there wouldn’t be much in her digestive tract during the day, and always wore a sanitary pad. Doctors misdiagnosed her, sex was a nightmare and her husband abandoned her after harshly accusing her of having poor hygiene.

Shamed by the continuous odor, she withdrew from friends and stayed home from church and other gatherings. She endured her shame in solitude, year after year.

Perhaps one million or two million women worldwide are enduring fistulas and leak stool or, more commonly, urine through their vaginas. These are typically impoverished women in poor countries where home births are the norm, who couldn’t get to a doctor in time for a needed C-section.
