Nick Jonas Opens Up About Living With Diabetes

Nick Jonas has written about being diagnosed with type 1 diabetes over a decade ago.

The singer posted a photo on Instagram of himself as a 13-year-old -- which was right around the time the Jonas Brothers recorded their first song.

"13 years ago today I was diagnosed with type 1 diabetes," the now 26-year-old explained.

"The picture on the left is me a few weeks after my diagnosis. Barely 100 pounds (just over 45 kilos) after having lost so much weight from my blood sugar being so high before going to the doctor where I would find out I was diabetic," he wrote.

Jonas went on to celebrate how much progress he's made in the last 13 years, and how putting his health first has paid off.

"On the right is me now," he said of his current-day selfie. "Happy and healthy".

"Prioritising my physical health, working out and eating healthy and keeping my blood sugar in check. I have full control of my day to day life with this disease, and I’m so grateful to my family and loved ones who have helped me every step of the way," Jonas said.

"Never let anything hold you back from living your best life. Thank you to all my fans for your kind words and support. Means more than you know. Love you all."

Jonas first went public with his diabetes diagnosis in 2007, saying he wanted "people to know I am not going to let this slow me down.”

He's among celebrities including Tom Hanks, Halle Berry, Billie Jean King and Bret Michaels -- who have also spoken publicly about living with diabetes.

According to Diabetes Australia, around 1.7 million people in the country have diabetes -- and that includes diagnosed and undiagnosed cases. Type 1 accounts for 10 percent of all diabetes while Type 2 accounts for 85 per cent of diabetes.
