According to , the doll was designed to accurately reflect the medical equipment that those with type 1 diabetes might use.

Barbie's outfit is also intentionally designed, featuring a blue polka dot top and matching skirt, as a nod to the symbols that represent diabetes awareness — a circle and the colour blue.

The doll also comes with an insulin pump and a continuous glucose monitor (CGM), which has heart-shaped medical tape in Barbie pink to keep the latter in place.

Additionally, Barbie's phone displays a CGM app that helps track blood sugar levels throughout the day.

"Visibility matters for everyone facing type 1 diabetes," said Breakthrough T1D director of marketing strategy, Emily Mazreku.
