The Medical Examiner’s report on Lisa Presley, who was 54 at her time of her death, ruled that she died from small bowel obstruction a complication of weight loss surgery.
The Los Angeles County Department of Medical Examiner confirmed the news Thursday and added that the manner of Presley’s death was natural causes.
A toxicology report showed “therapeutic levels of oxycodone” in Presley’s blood as well as traces of buprenorphine (an opioid that can be prescribed for pain relief) and quetiapine (an antipsychotic medication). The drugs were deemed “not contributory to death,” and “no evidence of injury or foul play” was found.
The autopsy report said she had been complaining of stomach pain earlier in the day.
For months, she complained of abdominal pain, fevers, vomiting and nausea but did not seek medical attention, according to the report.
Juan M. Carrillo, a deputy medical examiner in Los Angeles County, described Ms. Presley’s health problems after the bariatric surgery as a “known long-term complication of this type of surgery.”
