Over the last few years, Matthew Perry has been very open about his health struggles, including his addiction to alcohol and Vicodin.

The Friends alum revealed that while he was making people laugh on camera, behind the scenes he was going through "a very lonely time" because he "was suffering from alcoholism."

"It was going on before Friends, but it's a progressive disease," he explained. "I was never high at work. I was painfully hungover. Then eventually things got so bad I couldn't hide it and everybody knew."

His addiction got so bad that he doesn't even remember three years of filming the hit NBC sitcom.

Perry has been sober for years now, and has been using his experience to help other addicts recover.

"I've had a lot of ups and downs in my life. I've learned a lot from my failures, but the best thing about me is if an alcoholic comes up to me and says: "˜Can you help me stop drinking?' I can say, "˜Yes,' " he said.

In 2013, he opened up his own sober-living facility called Perry House after realizing that "getting sober is really hard thing to do" and having support is a big part of the journey.

While Perry has made great strides in recovery, he continues to deal with other health issues.

The 48-year-old actor had to recently undergo surgery to repair a gastrointestinal perforation (GP). Perry's rep confirmed that the procedure was successful and he is on the road to recovery.

"Matthew Perry recently underwent surgery in a Los Angeles hospital to repair a gastrointestinal perforation," the rep told People. "He is grateful for the concern and asks for continued privacy as he heals."

According to Healthline.com, a gastrointestinal perforation is a "life-threatening condition" that "occurs when a hole forms all the way through the stomach, large bowel, or small intestine. It can be due to a number of different diseases, including appendicitis and diverticulitis. It can also be the result of trauma, such as a knife wound or gunshot wound."

While it's unclear what caused Perry's illness, excessive consumption of alcohol and smoking can increase the risk of developing digestive conditions like GP.

We're wishing Perry a speedy recovery!
