Reality star Rob Kardashian has been off the radar for a while, and now there's a report that he's had a health scare.

It was reported that the 28-year-old was diagnosed with diabetes after falling ill over the holiday and being taken to the hospital.

Kardashian dropped out of sight more than a year ago after being an integral part of his family's reality show "Keeping Up With the Kardashians" and his sister's now-canceled series "Khloe and Lamar."

There was talk that he had gained weight, and that increased in June after the Daily Mail published photos said to be of him making a late night fast food run.
