Rob Kardashian's weight gain is seriously endangering his life as doctors warned momager Kris Jenner's son to change his lifestyle or he could face death.

In the episode of "Keeping Up with the Kardashians" Sunday night, a doctor advised momager Kris Jenner's only son that he could develop diabetes and possibly organ failure if Rob Kardashian continues his weight gain trajectory.

That's when momager Kris Jenner became angry as she pointedly told her son: "Your liver is shutting down. This is life-threatening at this point. You can only sustain this level of being unhealthy for so long."

The sock designer reportedly tipped the scales at 260Ibs. after gaining 70Ibs following his breakup with actress Rita Ola, who cheated on her with other men.

Rob Kardashian then acknowledged that he has to reverse his situation and his personal trainer even praised his hard work.

Mirror reported that Rob Kardashian was fully aware of his situation and it has made him depressed.

"I've never felt so down depressed in my life," he told Khloe Kardashian weeks ago. "I'm trying to be in the fashion industry and I'm not going to be taken seriously when I'm fifty pounds overweight. It's embarrassing to the family."

Rob Kardashian's weight gain has become a problem to the extent that he is already considering of getting major stomach surgery to take off the excess pounds, the National Enquirer said.

The publication said that Rob Kardashian really hates the gym, which explains why his weight loss is not progressing.

"But he's under strict orders from Kris to lose 70lbs before Kim's wedding to Kanye West this summer," the source told Enquirer, adding that the only way for the reality star to lose that much weight in so short a period of time is "getting his stomach stapled."

"This procedure is a major operation. But being the ugly duckling in the family has affected Rob deeply. Everyone's worried about him," the source added.
