Rob Kardashian will have to make some serious changes in his lifestyle after being hospitalized in Los Angeles over the weekend. The former star of E!'s "Keeping Up With the Kardashians" was reportedly diagnosed with diabetes, which may or may not have been caused by his weight gain. Sources say Rob, 28, is using the incident to better himself and get on the right track.

According to E! Online, the Arthur George sock designer has been released from the hospital and is feeling much better. He was taken to the medical center after falling ill during the holiday weekend. Doctors found that his blood sugar levels were extremely high and quickly pinpointed diabetes as the issue. Sources say his hospitalization has served as a sort of "wake-up call." Treating physicians are said to have advised him to slim down, work out and make changes in his diet if he wants to feel better. 

As was previously reported, Rob was unaware he had been living with the condition. The youngest of the Kardashian children has spent much of the last few years hiding from the public eye to avoid scrutiny over his weight gain. According to various reports, he has put on over 100 pounds in recent years. TMZ reports he is making his health a priority in 2016.

Rob was last seen in October, driving his older sister Khloé Kardashian's Range Rover in Los Angeles. The sighting occurred shortly after it was reported that Lamar Odom, Khloé's estranged husband, had been hospitalized following an incident inside a Nevada brothel. It remains unclear where Rob was driving. He resurfaced on social media around the same time, sharing a hopeful message for Lamar, 36.
