Jamie Sangouthai's death was caused by more than just drugs.

Lamar Odom's Friend Jamie, A 'KUWTK' Guest Star, Has Died

According to the recently released autopsy, the 37-year-old Keeping Up With The Kardashians guest star was suffering from a flesh-eating disease, when he tragically passed away earlier this month.

“There are two causes: A.) Necrotizing Fasciitis. This is a skin disease and flesh eating disease. And B.) Chronic Intravenous Narcotism. This is associated with dirty needles, injections and drug use,” Lt. Fred Corral of the Los Angeles County Department Of Medical Examiner revealed to Hollywood Life on Wednesday.

Added Craig Harvey, Los Angeles County Coroner Spokesperson, “He went to hospital complaining about swelling and pain in his left arm after using intravenous drugs several times a day for several years."

Following the news of Sangouthai's passing, both Khloe Kardashian and Malika Haqq released statements to fans online.

Lamar Odom, who knew Sangouthai since they were young, is understandably shaken up by his friend's sudden death.

"It's very scary when someone you know so well dies suddenly," an insider close to Odom told E! News. "It's been a wake-up call for Lamar as he realizes that he could personally be in a very different place if he was still as close to Jamie."
