Rob Kardashian's doctors warn of deteriorating health of entrepreneur and ex-reality TV star

Doctors treating Rob Kardashian have warned his family that the former reality TV star has serious kidney and pancreas problems. The 28-year-old was rushed to hospital on 29 December after falling ill.

He was diagnosed with diabetes as doctors told him that he needs to lose weight, exercise and dramatically change his diet. According to MSN a family insider reportedly told Radar that the 28-year-old's health is deteriorating. "His pancreas is basically not functioning. He also has kidney problems. He's very, very sick," said the source.

"Of course Rob is scared right now and he should be. His health is the worst it has ever been and, diabetes aside, he has to overcome the mental health issues that seem to be at the center of all of this," the source added. "Everyone is urging him to go to rehab, whether it be a physical rehabilitation rehab or a drug program. The kid needs help and if he does not get the help he will not be around to see 2017."

Rob has kept out of the public eye in recent years after it was reported he was battling with depression following his weight gain. He missed his sister Kim's wedding to Kanye West and was absent from the family's recent Christmas festivities. He has withdrawn largely from public life and also unfollowed half his family from Twitter.

The sock entrepreneur rarely speaks out in publicly, but he did show support for his stepfather Bruce Jenner via Twitter, following the Olympian's interview with Diane Sawyer in which he revealed he was transitioning into a woman.

He has reportedly refused to see anyone in his family except his sister Khloe who he lives with. A source added: "Rob does not want to see anyone and he has made that very clear to the whole family. He is not answering calls or returning anyone's text messages."

Rob's mother Kris Jenner was on holiday with her daughter Kendall and the model's rumoured boyfriend Harry Styles, when he was taken into hospital, but is said to have rushed home to support her son.

While Rob has apparently taken the latest diagnosis as something of a "wake up call", it is thought he remains unconvinced about entering a rehabilitation facility.
