Renee Williams
Renee Williams was an American woman believed to be the largest woman in the world at the time of her death in 2007 from complications following her surgery for morbid obesity. Williams was also one of the heaviest people to ever live and one of the heaviest ever to undergo gastric bypass. By the age of 12, Williams was already in the category of super-morbid obesity, which refers to a body mass index over 50. After a car crash in 2003 she became unable to walk, which further contributed to her weight gain.
