This year, the number 20 holds special significance for iconic singer Nick Jonas.

While the band commemorates their 20th year as a band, 2025 also marks 20 years since their frontman's type 1 diabetes diagnosis.

“It’s crazy how it lined up,” the singer stated. “It's been an incredible ride in both… in the Brothers sense, it’s been the adventure of a lifetime, and we’ve been so fortunate to be able to do this for 20 years now and to have the support of the most amazing fans.”

Alongside the band’s experience over the last two decades, he said he has had great and tough moments managing diabetes. The struggles of managing his condition have been the low points, while raising awareness and connecting with others through his role and through his non-profit have brought him joy.

“Overall, I’m really grateful to have been able to be open about [type 1] and to connect with all these amazing people from all regions of the world who are navigating their own diabetes journey, and it’s a really significant feeling to feel like you’re a little less isolated in it,” said Jonas.

Nick Jonas’ A1C Shoutout to Fans

To thank his fans, on World Diabetes Day (November 14), he stepped onto the platform during a Jonas Brothers concert and surprised his audience by sharing an uplifting message of hope, accompanied by a shout-out to his A1C.

“My A1C, which is a average of numbers over a 90-day period, was the most favorable it’s ever been, in fact, most recently,” he revealed.

The show was attended by members of a worldwide group — a collective of more than 30,000 people worldwide who discuss their experiences with diabetes to help promote a message of strength, perseverance, and optimism.

“It was really meaningful for me to get to use the Jonas Brothers’ stage as a place to speak about something that’s clearly very personal to me and on World Diabetes Day, I think it’s fitting to get reflective and to tap into kind of what life looks like for me as a now 33-year-old person living with this disease,” he said.

Jonas dedicated the song “A Little Bit Longer” — a tune he wrote early in his career and diabetes journey, to those living with the disease.

“It’s a really significant time for me to get to speak on stage like that and play a song that I wrote about these experiences when I was 14 and to see the impact it still has to this day with the audience,” he said.

While the song has assumed a new meaning for him as an adult, he said it is still pertinent.

“Now I [have] this vast, supportive community that I am part of that has supported me in so many different moments. I think my outlook is possibly a lot more optimistic now. It is feasible to live a full, active life while living with this disease and outlook and viewpoint and all that is an important piece to persevering.”

Progress in Type 1 Diabetes

Not long ago, life with type 1 diabetes involved more than five insulin injections a day and glucose checks 10 or more times daily. This was a constant cycle of injections, estimation, and vigilance, according to a licensed endocrinologist.

“Insulin pumps replaced multiple daily insulin injections. With time, insulin pumps became lighter and more advanced, and eventually learned to ‘talk’ with the sensors,” the doctor noted.

“Algorithms began adjusting insulin automatically, creating hybrid ‘automated delivery’ systems that lift some of the mental burden people with type 1 bear every day.”

Jonas is amazed with how far technology has advanced since he was first diagnosed.

“The fact that I can receive real time readings of my glucose straight to my phone or smart watch or it can be [shared with] my wife or other family members when I am apart from is just an incredible thing,” he said.

Alongside technology, new therapies aimed at managing diabetes and slowing or modifying the disease itself are being researched.

“The first immunotherapy capable of postponing type 1’s onset was authorized, and research into preserving or even replacing the body’s insulin-producing cells gained real traction. In labs around the world, scientists are cultivating lab-grown pancreatic beta cells and experimenting with ways to protect them from immune attack,” the doctor continued.

“Responsive insulin” is also being developed to activate only when glucose levels rises, promising a future where insulin works as naturally as the body once did.

“More advancements will definitely continue to develop. We’re no longer just improving tools; we’re getting nearer to changing the disease itself,” the physician stated.

However, while another medical professional agrees that additional innovations will continue to develop, he notes that managing type 1 diabetes remains an intensive undertaking — physically, cognitively, and emotionally.

“I sincerely hope that we’ll see more and more focus to talking about and addressing the challenges and the demands of having and managing T1D. We need much more of that, too,” he told.

The Singer Employs Personal Wellness to Control His Diabetes

Beyond medication and technology, Jonas discussed some strategies he leans on to manage his diabetes.

First, he said he learned to take pressure off himself.

“You’re never going to have the perfect day living with this disease and even if you’re very diligent with your diabetes management, there are just things that are a little out of your control and being able to take a deep breath, recalibrate, and know that it’s going to be OK on the other side is really important,” he said.

While this is difficult to do at times, he said he learned to apply this soon after his diagnosis.

Recently, he has prioritized taking vitamins, caring for his skin, and staying well-hydrated.

“It’s a basic thing, but the more water I drink, my glucose levels are better. I don’t know precisely why, but I just find that hydrating has a lot of health advantages,” he noted. “I didn’t put as much focus on it earlier in my life as I do now, and it’s been really helpful.”

He also walks daily for 30 minutes or longer for his bodily, mental, and psychological health.

“It really centers me and even when it’s cold out, getting out in the fresh air is really important when a lot of my day, too, is spent inside for hours at a concert hall or on a film set or something,” he said.

He relies on his therapist regularly, too.

“I think it’s really vital to do that personal development,” Jonas said.

Most of all, he urges everyone managing type 1 diabetes to engage with the diabetes community.

“There will be positive days, there will be challenging days, but you can climb this mountain, and there’s some incredible people out there whose stories will really inspire anybody that’s going through tough moments,” said Jonas.
