Rob Kardashian  has been struggling with his weight lately, and it has been documented on his family’s reality show, “Keeping up with the Kardashians.” Now, it has been revealed that he has checked into rehab to deal with addiction problems.  

The 26-year-old has reportedly checked himself into rehab at The Meadows trauma and addiction treatment center in Arizona. According to reports, Kardashian has gained weight due to smoking marijuana, drinking alcohol and prescription cough syrup. “Rob has been checked into The Meadows for about a month for substance-abuse issues,” a source tells Star magazine.

On the mid-season finale of "Keeping Up With The Kardashians," last month, fans saw Rob break down after opening up about his battle with the bulge. The episode revealed that Rob’s health has been declining since gaining a significant amount of weight.

“If he doesn’t change his lifestyle right away, he’s going to end up diabetic and his organs are going to shut down,” Kris told daughter Kim, in response to his blood tests results.

Kris later sat down with her son, and told him the news. “I don’t wanna see something horrible happen to you [sic]. Your liver is supposed to be between 0 and 44. It’s 217. Your liver is shutting down.”

Later in the episode, Rob expresses his insecurities, telling Kim, “I don’t really wanna film with my shirt off. … I'm sad. I don’t’ even wanna sit down because of how fat I am [sic]. I don’t know I just don’t know what to do.”
