Mattel introduced its first-ever Barbie doll with type 1 diabetes in an effort to improve representation and produce dolls that truly mirror real life. Created in partnership with Breakthrough T1D, a nonprofit focused on type 1 diabetes research and advocacy, the new Barbie aims to normalize life with the condition and inspire empathy, understanding, and pride.

According to the Centers for Disease Control and Prevention, 304,000 children and teens in the U.S. were living with type 1 diabetes in 2021. For many, the new doll marks a much-needed shift in visibility. “It’s an honor to work with a brand that shares our commitment to showing children that a life with type 1 diabetes can be full, vibrant, and empowering,” said Aaron J. Kowalski, CEO of Breakthrough T1D. “This partnership is deeply personal—it means the world to be part of bringing greater visibility to a condition that affects so many families.”

Designed with accuracy and heart

The new doll is a cheerful, fashion-forward addition to Barbie’s Fashionistas lineup, which now includes more than 175 dolls with diverse skin tones, body types, disabilities, and styles. To reflect real-world experiences with type 1 diabetes, this Barbie comes with:

• A Continuous Glucose Monitor (CGM) on her arm, secured with heart-shaped medical tape
• A small insulin pump attached to her waist
• A smartphone app that tracks her glucose levels
• A polka dot outfit inspired by the international blue circle symbol for diabetes awareness
• A purse to carry snacks and medical supplies

Mattel worked closely with Breakthrough T1D to ensure the design reflected real tools used in diabetes management.

An empowering message

For kids who use insulin pumps or wear CGMs themselves, seeing these devices on a doll can offer powerful affirmation. It’s also a valuable opportunity for children without the condition to learn through play. The goal, according to Mattel, is not only to reflect the lives of kids with type 1 diabetes but to help foster empathy and reduce stigma.

A moment of celebration and advocacy

To launch the new doll, Mattel donated the first batch to young attendees of the Breakthrough T1D 2025 Children’s Congress. These kids, ages 4 to 17, traveled to Washington D.C. to speak with lawmakers about the need to fund diabetes research and support families affected by the disease.

The doll is now available to the general public and can be purchased online through Mattel as well as major retailers.

Representation matters

This addition to the Barbie universe is part of a broader mission to reflect real lives and support kids in all their beautiful complexity. From vitiligo and hearing aids to prosthetic limbs and wheelchairs, Barbie has steadily evolved to better reflect the world kids live in.

As Barbie’s universe continues to grow, so does its power to help kids feel seen, supported, and empowered.
