EAGLES founding member Glenn Frey died after battling arthritis for 15 years, his manager has revealed.
Irving Azoff also claimed the drugs he was taking for the condition caused the complications, which led to his death.
Frey, 67, had been admitted to a New York hospital in November and placed in an induced coma. But he failed to respond to treatment and died on Monday.
Mr Azoff said the drugs caused acute ulcerative colitis - a bowel disease that causes ulcers in the colon - and pneumonia.
He said: "The colitis and pneumonia were side effects from all the meds."
Mr Azoff said rheumatoid arthritis affected Frey's health on a daily basis, adding: "One day his knees would hurt, his hands hurtit moves from joint to joint".
The guitarist, who co-wrote the band's biggest hit Hotel California with Don Henley and Don Felder, began having intestine trouble in the 1970s due to his chronic cocaine addiction.
He suffered stomach ulcers and had his nose rebuilt twice, with Teflon replacing the membrane the second time.
Frey's habit reached its peak during the eight-month recording session for the Hotel California album in 1976. He used to arrange lines of cocaine in an "aerodynamic" crescent and snort an eighth of a gram at a time.
Frey formed Eagles in Los Angeles in 1971 with Henley, Bernie Leadon, and Randy Meisner. They became one of the biggest bands of all time, selling more than 150 million albums around the world.
They split acrimoniously in 1980 after a string of hits including Take It Easy, Lyin' Eyes and One of These Nights.
In 1986, Frey missed a reunion concert with Henley because of an intestinal disorder.
An attempt to reform the band in 1990 was put off, in part, because of surgery to remove part of Frey's intestine. In 1994, their reunion tour was interrupted by more health problems.
After Frey's death, Henley described him as a brother and added: "It will be very strange going forward in a world without him in it. But, I will be grateful, every day, that he was in my life."
Rocker Huey Lewis called Frey "a brilliant songwriter and a really good guy. Talented, funny, cynical and sweet".
Frey married his second wife Cindy Millican in 1990. They had a daughter, Taylor, and sons Deacon and Otis.
