It landed Travis Barker in hospital – here's everything you need to know about pancreatitis

When he was rushed to hospital with a "mysterious disease" fans feared the worst. Then came the news Travis Barker had pancreatitis and there seemed to be some relief that it was nothing more serious. 

But it can indeed be serious and Travis' daughter, Alabama, asked people to pray for her father when he was in serious pain. The pancreatitis is believed to have been because of a recent colonoscopy procedure. 

The musician is still in hospital with wife Kourtney Kardashian at his side. "Travis was suffering from extreme stomach pain and could barely walk," a source told People magazine.
