In 2025, the number 20 holds special significance for iconic singer Nick Jonas.

As the Jonas Brothers celebrate their 20th year as a band, 2025 simultaneously signifies 20 years since their lead singer's type 1 diabetes discovery.

“It’s crazy how it lined up,” Jonas remarked. “It’s been a wild journey 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 world’s greatest fans.”

Parallel to the band’s experience over the last 20 years, he said he has had great and tough moments living with diabetes. The struggles of controlling his disease have been the low points, while raising awareness and connecting with others as a spokesperson and through his foundation have been a source of happiness.

“In summary, 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 experiencing their own diabetes path, and it’s a really significant feeling to feel like you’re a little less alone in it,” he added.

The Singer's A1C Announcement to His Audience

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

“My A1C, which is a average of numbers over a three-month period, was the best it’s ever been, actually, most recently,” said Jonas.

The show was attended by members of a worldwide group — a network of more than 30,000 people globally who share their experiences with diabetes to help spread a message of resilience, perseverance, and positivity.

“It was really special for me to get to use the Jonas Brothers’ stage as a place to speak about something that’s obviously very personal to me and on World Diabetes Day, I think it’s fitting to get reflective and to explore sort of what life looks like for me as a now 33-year-old person living with this condition,” 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 effect it still has to this day with the audience,” he said.

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

“Now I [have] this great, big 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 possible to live a full, active life while managing this disease and outlook and perspective and all that is an important piece to powering through.”

Advancements in Diabetes Management

In the past, life with type 1 diabetes meant more than five insulin injections a day and finger sticks 10 or more times daily. This was a constant cycle of needles, estimation, and care, according to a board certified endocrinologist.

“Insulin pumps replaced multiple daily insulin injections. With time, insulin pumps became less bulky and smarter, and eventually learned to ‘communicate’ with the glucose monitors,” the expert explained.

“Algorithms began adjusting insulin on their own, creating hybrid ‘automated delivery’ systems that alleviate some of the cognitive load people with type 1 carry every day.”

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

“The fact that I can receive instant data of my glucose straight to my phone or smart watch or it can be [shared with] my wife or other family members who I’m traveling away from is just an incredible thing,” he said.

In addition to technology, new treatments aimed at controlling the condition and delaying or altering the disease itself are being researched.

“The first immune-therapy capable of postponing type 1’s start was approved, and research into preserving or even substituting the body’s insulin-producing cells acquired real traction. In labs around the world, scientists are cultivating lab-grown pancreatic beta cells and testing ways to protect them from immune attack,” the doctor continued.

“Smart insulin” is also being engineered to become active only when blood sugar increase, promising a future where insulin works as naturally as the body once did.

“Further progress will absolutely continue to develop. We’re no longer just improving tools; we’re getting nearer to changing the disease itself,” the expert concluded.

However, while another medical professional concurs that further advancements will continue to develop, he points out that managing type 1 diabetes remains an demanding undertaking — physically, cognitively, and psychologically.

“I sincerely hope that we’ll see more and more focus to talking about and helping with the challenges and the demands of living with and controlling T1D. We need far more of that, too,” he told.

The Singer Employs Self-Care to Manage His Diabetes

In addition to medication and technology, Jonas shared some strategies he relies on to handle his diabetes.

To begin, he said he learned to take pressure off himself.

“You’re never going to have the ideal day while managing this disease and even if you’re super on top of your diabetes management, there are just things that are a little out of your control and being able to take a deep breath, reset, and know that it’s going to be OK on the other side is really crucial,” he said.

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

Lately, he has focused on 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 exactly why, but I just find that drinking water has a lot of health benefits,” 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 physical, cognitive, and psychological health.

“It really grounds me and even when it’s cold out, getting out in the open 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 self-work,” Jonas said.

Most of all, he urges everyone living with type 1 diabetes to take part in the diabetes community.

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