More details are emerging about the tragic death of Elvis Presley's only child six months after her passing. 

Lisa Marie Presley died at age 54 on Jan. 12 following a medical emergency that required hospitalization, her mother Priscilla Presley previously shared. 

Now, her cause of death has been revealed as complications resulting from small bowel obstruction, according to records from the County of Los Angeles Medical-Examiner reviewed by E! News. 

Small bowel obstructions are blockages in the small intestine that can be caused by numerous factors including hernias, inflammatory disease or tumors, per the Cleveland Clinic.

In Lisa Marie's case, she suffered from "a strangulated small bowel" that was caused by "adhesions" that developed after she had bariatric surgery—a type of weight loss surgery that changes the digestive system—that was done years ago, according to an autopsy report obtained by NBC News on July 13. It stated that the medical issue is a known complication of the surgery.

Lisa Marie's cause of death has been ruled as natural.

On Jan. 12, Priscilla, 77, released a statement saying her daughter had been hospitalized and, hours later, shared news of Lisa Marie's death.
