Viewers were concerned when the usually bubbly and outgoing star appeared quite subdued during her time in the CBB house and it was not until she left that it was revealed she had been battling the illness throughout the programme.
Sam told This Morning's Phillip and Holly: "I cannot explain how gutted I was - I was so excited to be in the Big Brother house. When I got in there I was fine, I didn't feel stressed or nervous I was just really excited.
"Obviously I do reality, so for me it was just like a whole new door opening for reality and for three to four days I was absolutely fine, I was just getting to know people.
"It was five days in when the symptoms hit really hard.
"It was really, really bad stomach cramps - I would be doubled over with tears to my eyes.
"I couldn't hold food down so every time I was eating or drinking something, within minutes it was either sickness or diarrhoea."
The symptoms Sam was suffering caused her to drop around a stone and a half in weight, and matters where made worse when the doctors seemed unsure as to what was actually wrong.
"I saw the doctor a couple of times while I was in there and they said it could be IBS (Irritable Bowel Syndrome)," Sam explained.
"Then they were thinking it could be a really bad virus or a tummy bug because the pains were bad.
"And as the days were going on I could see myself losing more and more weight...and that's when I thought "this can't just be a tummy bug".
"There were a couple of days in the house when I couldn't even get myself out of bed, my whole body was aching, now that I have done some research I know these are signs of a flare up of Crohn's disease."
After weeks of tests Sam was finally given a clear diagnosis on Friday and while there is no cure for Crohn's Disease, it is a treatable condition.
The TOWIE star admitted she was glad to finally know what she was dealing with and was adamant she would remain positive about managing her condition.
