The post-mortem results released by Los Angeles County Medical Examiner-Coroner on Thursday ruled her death as being from natural causes due to effects of a small bowel obstruction.
It said the complication was the result of bariatric surgery - a weight loss procedure - from several years ago.
"The obstruction was in the form of a strangulated small bowel caused by adhesions that developed after bariatric surgery years ago," the examiner said in a report.
"This is a known long-term complication of this type of surgery."
The examiner said she also had a history of overmedicating in which, forgetful about her prescription medication, she would repeat her doses.
The toxicology report showed she had “therapeutic levels” of oxycodone and other medicine in her blood that were not considered contributing factors.
Ms Presley - who was last seen in public at the Golden Globes two days before her death - had complained of stomach pain earlier in the day, according to the report.
In the clip, Lisa Marie - who died after she suffered a cardiac arrest at her Calabasas, California home - turned to her friend Jerry Schilling, 80, and said 'I'm gonna grab your arm' as she was asked questions ahead of the event by Extra host Billy Bush.
She appeared to talk slowly and slurred her words while talking about the film's star Austin Butler and the storms and flooding in Southern California.
Lisa Marie Presley haunted by Graceland's 'damn back lawn' and what it containsElvis daughter Lisa Marie used treats Graceland like "home" but once confessed she struggles with the "mother***ing back lawn."
Lisa Marie still visited her childhood home every Christmas and was one of very few people to have access to the upper floor which houses ust her bedroom and that of her father. She still entertains friends there, using the kitchen and dining room.But one part of the grounds has been particularly troubling to the rock 'n roll heiress – and understandably so.
She went on the explain why she feels that way about Graceland's back garden, and why it haunts her years later.
Lisa Marie said: "The back lawn of Graceland is a graveyard, basically.
"How many people have a family grave in the backyard? How many people are reminded of their fate, their mortality, every ****ing day?"
She went on to talk about whether she would also be buried there – something which became even more heartbreakingly likely after the tragic events of 2020. 'I wish my son had lived to see this'
Elvis' only grandson Benjamin Keough, who is buried by The King at Graceland, has received a rare new touching tribute from his mother Lisa Marie Presley. The music icon's daughter also shared how "it breaks my heart" that her son isn't alive to see Baz Luhrmann's Elvis movie, saying he would have "absolutely loved it" as much as she did."
But then Lisa Marie's son, Benjamin Keough, died of self-inflicted gunshot wounds in a horrific accident on July 12, 2020. He, too, is now also buried at Graceland with his family.
Recently Lisa Marie Presley's half brother Navarone Garibaldi has recently married, shares his mother Priscilla Presley, who also posted photos confirming a touching connection to Elvis.
Elvis only married once to Priscilla Presley and together they had The King’s only child, Lisa Marie Presley. The celebrity couple’s daughter was born exactly nine months to the day from their wedding night on February 1, 1968. Her parents later divorced in 1973 and from 1984-2006, Priscilla’s partner was screenwriter turned computer programmer Marco Garibaldi, with whom she had a son. (Express)
