Randy Jackson Raising Awareness About Diabetes What's up dawg? Did you know that "American Idol" judge Randy Jackson was diagnosed with type 2 diabetes about five years ago? He has it under control now, since he lost 110 lbs through gastric bypass surgery, improved his diet, exercises, and sees his doctor regularly. Back then, though, he had no idea. He was feeling really rundown and had a high fever, almost like he had a cold, and when he finally saw a doctor, he found out the surprising news.
