3. Cause of death
Decades after The King died, his former friend and personal physician, Dr. George Nichopoulous came forth with a weird theory stating that the King hadn’t died of cardiac arrhythmia. Instead, he claims that the cause of death was chronic constipation, leaving everyone rather baffled. It’s not that long until 2027 and we’ll know for sure when the autopsy files are released. Until then, this is one of the 6 Elvis Presley conspiracy theories.
