Keeping Up with the Kardashians star Rob Kardashian was hospitalized and later diagnosed with diabetes during a recent hospital visit, according to a TMZ report.

Reports say Rob was taken to the hospital over the weekend when he wasn’t feeling well. TMZ reported that the 28-year-old reality star was unaware of the condition that doctors had diagnosed him of.

A source told E! News on Tuesday that Rob had returned home from the hospital and is “fine now.”

“It was a wake up call,” the source said, adding that doctors told Rob that he needs to lose weight, exercise and dramatically change his diet, or his condition will get worse.

“He’s OK. He’s just working on himself a little bit and trying to be a better Rob, so I just have to trust that he’s good,” Kris Jenner recently told E! News’ Maria Menounos. “We’re all here to support him for whatever he needs, but he’s doing OK.”

Rob Kardashian dated actress Adrienne Bailon from 2007 until 2009. Their relationship was documented on the family reality show Keeping Up with the Kardashians. After months of speculation in October 2012, Kardashian confirmed through his Twitter account that he and Rita Ora were dating. In December 2012, it was revealed that their relationship had ended.

He graduated from the University of Southern California’s Marshall School of Business in 2009.
