Rob Kardashian, the youngest of the Kardashians, has been diagnosed with diabetes, TMZ has reportedly learned. 

TMZ reports Rob was taken to an L.A. hospital over the weekend after feeling ill and only getting worse. It was there that doctors ran tests and broke the news to Rob that he had diabetes. Rob was reportedly stabilized but remains hospitalized. Sources told TMZ the diagnosis has jolted Rob into taking the reins on his health starting the new year off for 2016.

Rob has been keeping out of the public eye while battling weight issues and depression stemming from that, both documented in episodes of Keeping Up With the Kardashians. He has notably missed Caitlyn Jenner being honored at the ESPYs this year and his sister Kim's wedding. In the past his sisters have tried to help him work out his issues. Khloé talked about Rob in a recent People interview saying, "It's sad, because he's only wasting his life more and more. But he has to figure it out for himself. And he has so many people who want to help him." 

She recently posted this throwback photo of the two on her Instagram: 

 

If only you could see yourself through my eyes! I'll forever be obsessed with you! My one and only! #MyAce
