UFC middleweight champion Georges St-Pierre followed up comments made by UFC president Dana White that he is currently undergoing a battle with a medical condition.

St-Pierre, who returned to the Octagon and captured the belt last month with a submission win over Michael Bisping, posted a message this past weekend on his official Facebook account indicating that he has been diagnosed with ulcerative colitis.

“I now understand the health issues that I had during my last training camp,” he wrote. “I hoped my condition would improve after the fight but unfortunately it got worse and I had to go straight to the hospital for a colonoscopy when I came back from vacation last Wednesday.

“The diagnosis is ulcerative colitis and I am now taking medication that will hopefully appease the symptoms. My health is my (No. 1) priority right now, I’m still a very happy man, thanks for your support.”

The UFC was looking to book St-Pierre with interim champion Robert Whittaker in early 2018, but that appears to be off the table for now.

GSP stepped away from the sport and vacated the welterweight belt following a successful title defense vs. Johny Hendricks. He announced plans to return earlier this year, but his scheduled bout with Bisping was postponed until November.

St-Pierre joined Conor McGregor, Randy Couture and BJ Penn as the only fighters in UFC history to capture gold in multiple weight divisions.
