Nick Jonas has quietly been dealing with Type 1 diabetes for the last 14 years. The star took to social media to remember his diagnosis and to bring awareness to the "invisible illness" because November is Diabetes Awareness Month. "14 years ago this month I was diagnosed with Type 1 diabetes," Jonas wrote in the caption of the selfie he shared on Instagram. "This experience has shaped how I approach my health - working out, eating well, and always thinking about my blood sugar and insulin needs." Jonas continued, "You can't always see what goes into managing an invisible illness, and Type 1 diabetes can feel lonely and isolating. That's why I co-founded @BeyondType1 in 2015, to make sure no one feels alone with this diagnosis and to share how you can thrive with Type 1 diabetes."
