AceShowbiz - Nick Jonas was a day shy of falling into a coma when he was first diagnosed with diabetes as a teenager.
The "Jealous" singer's parents took him to the hospital when they noticed he was losing weight and craving soda, and medics discovered his blood sugar had spiked to dangerous levels because he had type 1 diabetes.
Jonas, who was 13 at the time, tells Cigar Aficionado magazine, "I was very close to a coma. Like, a day away, if I hadn’t gone to the hospital."
"I kept asking my parents, 'Am I going to be OK?' I was just so concerned that it was going to limit my ability to do all the things I wanted to do. I was very scared."
He adds, "I found out very quickly it's a very manageable disease - as long as you're really diligent."
