29-year-old Rob Kardashian is opening up about his health. Last year he was hospitalized due to complications from diabetes. He said it was a "big-time scare." Kardashian had type 2 diabetes and had stopped taking his insulin. He reached about 300 pounds and felt so insecure about his weight gain that he missed his sister Kim's wedding to rapper Kanye West. Now he says he's diabetes-free and is working to bring his weight down.
