Sam Faiers has reportedly been diagnosed with Crohn's Disease.
The Only Way Is Essex star fell ill when she was in the Celebrity Big Brother House last month, ending up on a drip and apparently losing more than a stone and a half in weight.
It was known that she was having tests in hospital and her spokesman has now told the Daily Mirror: "I can confirm Sam has very recently been diagnosed with Crohn's Disease."
A source said Sam, 23, is now on a carefully controlled diet and is working with a gastroenterologist to help her cope with the inflammatory bowel condition.
"Sam won't let things hold her back, she's dealing with it in the best way she can. She knows she can't change anything, but she can educate herself about the disease," said the insider.
