Lisa Marie Presley died from complications of a small bowel obstruction that was ultimately ruled a natural cause of death.

What the autopsy found

  • The Los Angeles County Medical Examiner determined her cause of death was a small bowel obstruction, meaning her small intestine was blocked and could not function properly.
  • The obstruction was described as a “strangulated” section of small bowel, which can cut off blood supply and quickly become life-threatening if not treated in time.

Link to prior surgery

  • The medical examiner reported that the blockage was caused by adhesions (internal scar tissue) that developed after bariatric weight‑loss surgery she had undergone years earlier.
  • These adhesions are a known potential long‑term complication of bariatric procedures and can, in some cases, lead to small bowel obstruction.

Cardiac arrest vs. underlying cause

  • Lisa Marie Presley was found unresponsive at home and suffered cardiac arrest, but the autopsy clarified that the underlying medical cause was the intestinal obstruction rather than a primary heart condition.
  • The manner of death was classified as natural, with no evidence of foul play.

Toxicology and medications

  • Toxicology testing showed “therapeutic” levels of certain medications, including oxycodone and other prescribed drugs, but the report noted they did not contribute to or cause her death.
  • Investigators therefore focused on the mechanical bowel obstruction and postsurgical adhesions as the key medical factors, rather than any overdose or substance‑abuse event.
