Bella passed away on July 11, a few days after her mother Kyla who had been put into a medically induced coma due to complications stemming from a viral infection in her lungs. Her mom shared a video of Bella's lively personality while she battled multiple life-threatening illnesses, including severe combined immunodeficiency (SCID) and the rare bowel illness Hirschsprung's disease, went viral on social media.

In a heartbreaking social media post, Kyla revealed the news that her daughter had died on Sunday afternoon. 'Our brave girl left her legacy here on earth to dance on streets of gold,' Kyla said. 'Bella passed peacefully in our arms.'

She shared a video of herself and her mom dancing to Big Boss Vette's "Pretty Girls Walk" in March of 2023. Bella Brave is an alternate name for her. The rare bowel disease Hirschsprung disease, which she was born with, completely destroyed her colon.

She was able to wean herself off total parenteral nutrition after being the first pediatric patient in Alberta and Saskatchewan to take the medication Revestive.

She became famous after posting videos of herself dancing in the hospital, documenting her health struggles and triumphs through fashion, beauty by Bella, and comedy. Severe combined immunodeficiency is another name for it. On top of that, she's dwarfish and has cartilage hair hypoplasia.

What disease does Bella Brave have?

After falling into a coma from a virus, Bella may have developed Bronchiolitis Obliterans, an inflammation-related condition that blocks the smallest airways in the lungs. She still looks like a one-year-old because of her bone growth disorder, which also makes her hair grow sparsely and her skin light in color.

Her severe combined immunodeficiency (SCID) and Hirschprung's disease (a condition that causes problems passing stool) were among three genetic conditions that were identified soon after she was born. The quick decline in Bella's lung function, according to the doctors, may have been an immune response.

As Kyla mentioned before, Bella's critical medical requirements were identified at the three-day mark. A common cold could be fatal for Bella, who was diagnosed with SCID at 11 months of age, according to her parents. She had a bone marrow transplant at the age of fifteen months, following two months of hospital isolation due to the risk of infection—once again, the product of a genetic mutation.

At about the same time, her third hereditary disorder, cartilage hair hypoplasia, a type of dwarfism, was also identified.
