In 2025, the number 20 carries particular meaning for iconic singer Nick Jonas.

As the Jonas Brothers celebrate 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 a wild journey in both… regarding the band, 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.”

Parallel to the band’s experience over the last 20 years, he said he has had wonderful and challenging moments managing diabetes. The difficulties of controlling his disease have been the low points, while raising awareness and engaging others through his role and through his non-profit 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 wonderful people from all corners of the world who are navigating 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 show appreciation to supporters, on World Diabetes Day (November 14), he took to the stage during a Jonas Brothers concert and delighted his audience by sharing an inspiring message of hope, accompanied by a shout-out to his A1C.

“My A1C, which is a collection of numbers over a 90-day period, was the best it’s ever been, actually, most recently,” said Jonas.

The show was attended by members of a global community — a collective of over 30,000 people worldwide who discuss their experiences with diabetes to help promote a message of strength, determination, and positivity.

“It was really special for me to get to use the Jonas Brothers’ platform as a place to speak about something that’s clearly very important to me and on World Diabetes Day, I think it’s natural to get reflective and to explore kind of what life looks like for me as a now 33-year-old person managing this disease,” he said.

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

“It’s a really important 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 fan base,” he said.

While the song has taken on a new meaning 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 various moments. I think my perspective is perhaps a lot more positive now. It is feasible to live a full, active life while managing this disease and outlook and viewpoint and all that is an important piece to powering through.”

Progress in Type 1 Diabetes

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

“Insulin pumps superseded multiple daily insulin injections. With time, insulin pumps became lighter and smarter, and eventually learned to ‘communicate’ with the glucose monitors,” the doctor noted.

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

Jonas is impressed 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 amazing thing,” he said.

Alongside technology, new therapies aimed at controlling the condition and slowing or modifying the disease itself are in development.

“The first immunotherapy capable of postponing type 1’s start was approved, and research into protecting or even substituting the body’s insulin-producing cells acquired real momentum. In labs around the world, scientists are growing stem-cell–derived pancreatic beta cells and experimenting with ways to shield them from the body's defenses,” said the specialist.

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

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

However, while a family physician agrees that additional innovations will continue to appear, he points out that managing type 1 diabetes remains an intensive task — in terms of health, mentally, and psychologically.

“I truly hope that we’ll see more and more attention to talking about and helping with the burdens and the demands of having and managing T1D. We need much more of that, too,” he told.

Jonas Turns to Self-Care to Control His Diabetes

Beyond medication and technology, Jonas discussed some strategies he leans on to manage 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, recalibrate, and know that it’s going to be OK on the other side is really crucial,” he said.

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

Lately, 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 more stable. I don’t know exactly why, but I just find that hydrating has a lot of health advantages,” he noted. “I didn’t put as much focus on it when I was younger as I do now, and it’s been really helpful.”

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

“It really centers 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 indoors for hours at a venue or on a movie location 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 living with type 1 diabetes to take part in the diabetes community.

“There will be positive days, there will be challenging days, but you can scale this challenge, and there’s some incredible people out there whose experiences will really motivate anybody that’s going through difficult times,” he concluded.
