Nick Jonas, of the talented Jonas Brothers, has been very open about his long term struggles with Type 1 diabetes.
He was diagnosed at the age of 13. His blood sugar was over 700 at the time of diagnosis! He says he had lost a considerable amount of weight, could not quench his thirst, and was close to becoming comatose.
Today he manages his diabetes with an insulin pump and a healthy lifestyle. In addition to dancing, he works out 3-4 days a week. Nick is a big proponent of diabetes support organizations.
