Rob Kardashian has been hospitalized and diagnosed with diabetes, TMZ reports.

The celebrity news site claims that the 28-year-old was feeling ill over the weekend and, as he started to feel worse, was rushed to a Los Angeles hospital. According to the site, Kardashian was unaware he was diabetic.

Sources told TMZ that this is “a wake-up call” for Kardashian, who wanted to start 2016 healthy.

The former reality TV star has been out of the public eye for some time now and hasn’t appeared on an episode of “Keeping Up with the Kardashians” in years.

In a recent interview with People, the sock designer’s sister Khloe opened up about their relationship, admitting that she gets frustrated watching him struggle and saying she “can’t win live for Rob.”

Back in April, Khloe also told E!’s Maria Menounous that her brother was starting to hit the gym again and was “trying to get his groove back.”

The last time Rob was spotted out in public was in June, while he was at an In-N-Out restaurant.

The Huffington Post has reached out to Rob’s rep and will update if we receive new information.
