Bella Brave's health has taken a difficult turn. 

The TrendPulseTikToker—whose real name is Bella Thomson—has been intubated in the ICU and is now in a medically induced coma, her mom Kyla shared on social media. 

"They’ve told us they don’t know if she’ll survive this," Kyla wrote in a July 9 Instagram post. "I know she will. I know she has an army praying for her."

Just days before the update, Bella—who rose to fame by documenting her health struggles with Hirschsprung’s disease, a condition which impacts the bowel, and severe combined immunodeficiency—was battling a lung infection, which her mom shared had possibly developed into Bronchiolitis Obliterans, an "irreversible and chronic condition” also known as “popcorn lung,” according to the American Lung Association. 

At first, Kyla thought Bella was overcoming the illness, explaining, "She mesmerized the doctors by sitting up, chatty, but requiring 100 percent o2 on bipap & a bunch of other remarkable things that in this situation typically, the average kid would already be sedated and intubated." 

But shortly after, the 10-year-old's health took a turn for the worse. 

"We started the lung steroids but then her ability to keep her own energy up enough to expand her lungs to breathe was getting harder," Kyla explained. "She lost 4lbs in 1 day putting all her energy into breathing. Her co2 increased and she started to doze off & have delirium."

As a result, Bella's medical team decided that "they needed to sedated her and intubate before she crashed." 

"It gutted me to see her so alert asking for something to drink but having to tell her they need to give her ‘sleepy medicine’ first to fix her lungs," Kyla continued. "I then reassured her that after her nap we will have lots to drink. After that I couldn’t breathe or see from crying so much."

Noting that Bella's lungs "look perfect inside," Kyla went on to explain that the issue appears to be due to the organs "being stiff and difficult to expand and they need to figure out why."

She added, "They will figure out why & they will fix it, I refuse to believe anything less."

Amid Bella's health battle, fans of the influencer offered their support and well-wishes. 

"I don’t have words," one user commented under Kyla's post. "Just know that so many are thinking, praying, sending healing energy and holding your family close to our hearts." 

Another wrote, "I am on vacation and yesterday I purposely drove to a beautiful chapel to pray for Bella."
