Sam Faiers left the Celebrity Big Brother 2014 house for hospital yesterday after failing ill again.
The TOWIE star has been sick almost since Day 1 of the series and previously had to get treatment in the Diary Room.
However Channel 5 denied that she had actually left the house.
A spokesperson said at the time: "She was treated over the weekend in the Diary Room for a medical issue of a personal nature. After treatment, she was free to leave the Diary Room and join the other housemates."
Now though it has been reported that Sam did eventually leave the house later on in the week in order to attend hospital.
A Big Brother insider told the Daily Star newspaper: “This is serious. Sam is really struggling.
"It’s why she hasn’t featured as much in the highlights as she would have if she was fully fit.”
The source went on to suggest that bosses hope Sam can remain in the house until the final next Wednesday.
"Going on Celebrity Big Brother was like a dream come true for her but the whole experience has been a nightmare because of illness," they told the tabloid. “There are still five days to go to the final. Questions are being asked over whether she should maybe leave on health grounds.”
Evicted CBB housemate Liz Jones said earlier this week that Sam's illness was one of the reasons she hadn't gathered as much air time as most of the others.
“I’d love to see her really explode and lose her rag – but she is very controlled,” the journalist commented. “Sam has been accused of being quiet and boring but there is a reason. She has been ill for two weeks.
“Some days she was so bad they let her stay in bed because she was really sick. She has a virus. It hasn’t helped her time in the house.
“I gather none of this has been shown and people don’t know.”
Celebrity Big Brother airs nightly on Channel 5.
