Nick Jonas is opening up about his struggles with Type 1 Diabetes.
On Instagram, Jonas posed a side by side photo of himself-- one, when he was first diagnosed with the illness thirteen years ago, and the other, a current snap.
The caption gets personal, reading in part, "Barely 100 pounds 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. On the right is me now. Happy and healthy. Prioritizing my physical health, working out and eating healthy and keeping my blood sugar in check."
The CDC describes type 1 diabetes as an autoimmune disease, where the body attacks its own cells that produce insulin.
If left unchecked, it can lead to high blood sugar and cause many complications. Type 1 diabetes is most commonly found in children and young adults.
Jonas says he now has full control of his daily activities and will not let the disease stop him from living life to the fullest. He encourages his fans to do the same, and thanks those who have supported him.
The pair is expected to wed in a multi-day ceremony, stretching from Nov. 30-Dec. 2 in Mumbai, India.
