She basically died because she told the doctors she had taken miso. At this point she absolutely needed a D&C but because Georgia law said that's bAd, doctors risked losing their licenses to help her. And by the time they were going to, it was too late.
But hey, it was a woman who died, and she was black, so definitely not the kind of person they care about.
I did a quick Google search, and I'm guessing miso is the ulcer treatment misoprostol that you shouldn't take during pregnancy. A d and c is a dilation and cutterage, an invasive surgical procedure that removes something from the uterus. In this instance the something was a nonviable pregnancy that went awry from possibly the medication (or other factors).
Admittedly i was also confused about miso, and immediately thought soup? I was extremely incorrect
