There’s a scene towards the end of the new “Elvis” movie when you know the end is coming soon. Presley, as depicted by actor Austin Butler, collapses in a hallway minutes before being scheduled to take the stage at the International Hotel in Las Vegas.

Instead of rushing an unconscious Elvis to a hospital, manager Tom Parker --- played by a surprisingly villainous Tom Hanks -- declares that the show must go on and summons “Dr. Nick” to make it right. After a quick injection of stimulant drugs, Elvis recovers just enough to sing, dance and entertain an adoring crowd in a packed showroom.   

That one scene sums up how the real Elvis Presley spent his final years before dying of an apparent heart attack in 1977 at the young age of 42. Popping pills. Slurring his words. Deeply depressed. And driven to continue performing by “Colonel” Parker and others.

“They really tried to push Elvis beyond his capacity in the last few years of his life. He was disabled,” says Dr. Forest Tennant, a retired physician and pain management expert who is one of the last people alive to be intimately familiar with Elvis’ drug use and medical problems.

In 1981, Tennant was hired by an attorney for Dr. George Nichopoulos (Dr. Nick), who faced criminal charges in Presley’s death. Tennant reviewed the autopsy report, medical records and a confidential 161-page private investigation, and testified as a defense witness for Nichopoulos, who would be acquitted of charges of overprescribing drugs.

After the trial, Tennant remained curious about Elvis’ medical problems and continued his research while treating people with intractable pain. The knowledge and experience Tennant gained in the last 50 years led to his recent book, appropriately titled “The Strange Medical Saga of Elvis Presley.”  

Elvis did indeed suffer from heart problems aggravated by an excessive use of drugs, but Tennant believes the ultimate cause of his death was a connective tissue disorder called Ehlers-Danlos syndrome (EDS), a major cause of intractable pain and other chronic health problems.

A diagnostic screening tool for EDS didn’t exist when Elvis was alive and few physicians were even aware of the condition. But Tennant thinks Presley had all the symptoms of EDS, including an unusual degree of flexibility and double jointness that allowed him to swing his hips and gyrate wildly. Those sexy dance moves helped make Elvis famous, but they also foretold what lay in store for him.

“EDS is a genetic connective tissue collagen disorder, and what that means is that you are genetically predetermined to have your collagen in certain tissues either disappear or deteriorate or become defective, and to put it bluntly, you can have a rectal problem and an eye problem at the same time due to the same cause because your collagen is deteriorating in these tissues,” Tennant told my colleague Donna Gregory Burch in a 2021 interview. “If you get a severe case like Elvis Presley, your life is going to be very miserable, and you're going to die young unless you get vigorous treatments.”      

The day before he died, a dentist gave Presley codeine for an aching tooth, not realizing how sick he was or that codeine could cause his heart to stop. Elvis collapsed in the bathroom 24 hours later. His sudden death led to rumors that he died from an overdose or even a horrible case of constipation. The truth is more complex.

“Nothing happened to Elvis Presley that we don't have a good logical, scientific explanation for now. But certainly back in those days we didn't,” Tennant explained. “Elvis Presley had multiple diseases. He was terribly ill, and he died accidentally in some ways with a dentist giving him codeine for his bad tooth, and his bad teeth were also part of the same disease that gave him a bad colon and a bad eye and a bad liver. They were all connected.

“He had all these metabolic defects due to his genetics, and so the codeine built up in his system. He had this terrible heart, so he died suddenly, within seconds, as he was trying to sit on the commode.”

Fortunately, the “Elvis” movie spares us any final scenes like that – ending instead with actual clips from one of Presley’s last concerts. They show a tired and very sick man, aged beyond his years and sweating profusely. But he still sang like “The King.”
