Reports revealed that Lisa Marie Presley was dealing with a steady decline in health according to recent reports.
For months before her death, she had been suffering from fevers and bouts of vomiting, as reported by People magazine.
On the day of her death, it is known that Lisa Marie had complained of abdominal pains before being discovered unresponsive at her home.
Despite Elvis' only daughter having complained of abdominal pain for a few months before her death, no medical attention was sought.
Consequently, when her condition worsened rapidly and required urgent care, it was too late.
According to a recent report, Lisa Marie's condition during her time at the ICU after her cardiac arrest was extremely challenging for her physical body.
The troubled star reportedly experienced dangerous heart rhythms and required a temporary pacemaker to be implanted, resulting in admission into an intensive care unit for further medical management.
Unfortunately, the results of her scan showed that she had suffered from anoxic brain injury; and at 4:48 PM, things took an unfortunate turn when Lisa Marie went into cardiac arrest. Sadly, 20 minutes later she was declared dead.
After examination by the Los Angeles County Coroner, they concluded that Lisa Marie Presley's cause of death was due to small bowel obstruction brought on by complications from bariatric surgery.
According to TMZ, the coroner's report indicated that the obstruction in her small bowel was an outcome of bariatric surgery, one which had been carried out several years ago.
The report stated, "The obstruction was in the form of a strangulated small bowel caused by adhesions that developed after bariatric surgery years ago."
When diet and exercise have not been successful in helping to reduce obesity, bariatric surgery may be suggested.
This type of procedure can include a gastric band, sleeve gastrectomy, or a gastric bypass.
The Mayo Clinic states that this treatment option should only be used as a last resort after other forms of weight loss have been unsuccessful.
Additionally, the autopsy of Lisa Marie revealed the presence of opioids and other medications at the time of her death.
The toxicology report showed levels of Oxycodone and Buprenorphine that were considered "therapeutic" in her blood.
When Lisa Marie was taken to the hospital, a toxicology report revealed that in her system there were two types of medication - buprenorphine for pain relief and Quetiapine as an antipsychotic. The coroner also reported that upon arriving at her home, no narcotics were found.
