In 1977, Elvis Presley's death was announced following a cardiac arrhythmia. The star had a drug addiction problem at the time and his diet was deplorable for his health. The weakening of his heart was thus explained by his disproportionate lifestyle, which had been endangering his life for several years.However, the doctor and long-time friend of the rocker, George ‘Nick’ Nichopoulos, first questioned the causes of Elvis' death. The version that was given is in fact far from the truth.The shocking truth about the rocker's imageWhen asked by Foxnews.com, George Nichopoulos said, ‘After Elvis Presley's death, we weren't sure what exactly caused it, so I did some research and some of my colleagues called me from different cities and medical schools that were doing research on constipation and its consequences.’This revelation is amazing and the doctor who spent 12 years with the star added: ‘We didn't realise until the autopsy that his constipation was so serious.’ He then went on to say, ‘We just assumed that constipation was a side effect of the medications he was taking for his arthritis pain and insomnia.’The King Getty ImagesA preventable death Upset by the idea that they could damage his image, Elvis Presley had always hidden his constipation problems. According to Nichopoulos, the subject was extremely delicate to discuss with the star. According to the doctor, this is why the rocker had weight problems and he could still have been alive if he had agreed to do a colostomy. Elvis apparently refused the operation because his problems were so difficult to accept and hurtful to his ego.
