Grace Victory, 30, first developed mild symptoms two weeks ago but went into intensive care on Christmas Day after her breathing deteriorated. The previous day doctors had made the decision to induce the birth of her son, who was not due to be born until February.
In a family statement posted on Ms Victory’s Instagram profile her condition was described as “stable”.
It read: "Grace was admitted into intensive care on Christmas Day due to issues with her breathing & therefore they [doctors] had to make the decision of placing her into an induced coma, to give her body the rest it needs, in order to recover.
"We love her so, so much and we know she'll come out of this stronger than ever.
"She has dedicated her whole career to healing people, we now ask that you pray, to heal her."
The baby boy is “currently doing so well”, the family said, adding: “We love him so much.”
Ms Victory, from High Wycombe, shot to social media stardom with her series of candid videos addressing topics such as eating disorders and mental health.
Also known as “The Internet’s Big Sister”, she has more 221,000 YouTube subscribers. Replying to the family statement, Little Mix star Leigh-Anne Pinnock wrote: “Sending you so much love to you all.”
Model and campaigner Katie Piper said: "Keeping you in my thoughts and prayers Grace."
