He died at the tragically young age of 42. In the last years of his life, he suffered from obesity, drug addiction, depression, chronic insomnia, glaucoma, high blood pressure, liver damage, rheumatoid arthritis, chronic constipation and an enlarged colon
The coroner recorded the cause of death as cardiac arrhythmia, a condition that can be determined only in someone who is still alive. This has caused claims of a cover-up. What was not recorded was Elvis's addiction to the drugs codeine, Valium, morphine, and Demerol, just to name a few. While Presley's main physician, Dr. George Nichopoulos, was exonerated of criminal liability for the singer's death, the facts were startling. The Tennessee Medical Board, which investigated the case, found that Nichopoulos had prescribed Presley more than 10,000 doses of narcotics, amphetamines, and sedatives, and that was just in the first 8 months of 1977. The medical board suspended Nichopoulos for 3 months, and in 1995, his license was permanently revoked.
In 1994, coroner Dr. Joseph Davis reopened the Presley autopsy and stated "There is nothing in any of the data that supports a death from drugs. In fact, everything points to a sudden, violent heart attack." Polypharmacy undoubtedly contributed to Elvis's premature death, even if it was not the final cause.
Forensic historian and pathologist Michael Baden views the situation as more complex: "Elvis had had an enlarged heart for a long time. That, together with his drug habit, caused his death. But he was difficult to diagnose; it was a judgment call." Nichopoulos, who acted as Elvis's personal physician for the last 12 years of his life, claims chronic constipation killed Elvis in his bookThe King and Dr. Nick.
In a 2010 Fox News interview, he stated, "We didn't realize until the autopsy that his constipation was as bad-we knew it was because it was hard for us to treat, but we didn't realize what it had done."
According his autopsy, the diameter of Elvis's colon was 5 to 6 inches, which is about double the size of the typical person's, and instead of being 4 to 5 feet long, his colon was 8 to 9 feet in length.
"We found stool in his colon which had been there for four or five months because of the poor motility of the bowel." Nichopoulos noted that Elvis had inherited a condition called bowel paralysis, which made defecating difficult.
"He would get embarrassed," he said. "He'd have accidents onstage. He'd have to change clothes and come back because of the way we were trying to treat his constipation."
Treating the problem correctly in the early 1970s would have necessitated performing a colostomy. Elvis didn't want to have anything to do with it. "If they had done the colostomy then, he'd probably still be here," Nichopoulos said.
