Lisa Marie Presley autopsy reveals she had a "small bowel obstruction" that developed "after a previous bariatric surgery years ago." Bariatric surgery includes gastric bypass and other weight-loss procedures. The 54-year old made her last public appearance at this year's Golden Globes, two days before she died. The morning she passed away, Presley was complaining of "severe abdominal pain." She was later found "unresponsive" by a housekeeper.
