How Lisa Marie Presley's weight-loss surgery contributed to her death

A severe complication from weight-loss surgery done years ago is the reason for Lisa Marie Presley's death in January at age 54. The autopsy report shows she had a small bowel obstruction caused by scar tissue that formed in her intestine. It's a known but rare risk of bariatric surgeries. About 263,000 bariatric surgeries were done in 2021. Major complications can occur in about 4% of cases, and deaths are more rare. Experts say the operations are generally safe.
