We wouldn't want to go through it ourselves.

Now that I'm A Celeb is well underway, more and more info about the background of the show is being released. And while we wouldn't want to be in the jungle with them (we scream at the sight of a small spider), it seems like the contestants have to go through a very gruelling medical test before they even enter the show. Cosmo explains the tests that UK doctor, Daniel Fenton, would advise... and it's pretty in depth. The first thing Dr Daniel would check is the contestants weight, saying: "I’d be worried about allowing someone into the jungle if someone had a Body Mass Index of below 18.5 or well above 30.

"Whilst there's not necessarily a minimum or maximum weight limit, I'd want to make sure that the celebs were able to withstand weeks of eating much less than normal." Next on the list is testing their kidneys, with Daniel explaining: "To test this we would look at Urea and would be happiest if results were under 8 whilst results for Creatinine are desirable at less than 110. "For eGFR, we’d want a level of 60-90+ to make sure there is no suggestion of acute or chronic kidney disease." Right.... After testing the kidneys, Daniel would move onto their blood pressure. "Blood pressure would need to be in a nice healthy range as stress, unusual diet and lack of exercise and disturbed sleep may increase blood pressure.

"Even more importantly, it needs not too be too low, as dehydration and lack of food can also make blood pressure drop and make you more likely to faint. "For optimal blood pressure, I’d want 120/80 but for those on blood pressure medication, less than 140/90 would be sufficient." IBS is another major factor, since the celebs aren't used to eating tails and testicals (puke). "Making sure contestants don't have an irritable bowel or bowel condition is very important as worms and eyeballs [in trials] will surely definitely play havoc on the guts."

And last but certainly not least, Dr Daniel says that he would check them for mental health issues. "An overview of Mental Health to ensure there is no history of severe stress, anxiety or depression or other significant disorders such as psychosis, as starvation and the wilderness can really take its toll! "You would be surprised how much an effect being stranded with strangers can have on emotional wellbeing and it may contribute to anxiety and panic attacks." So there you have it... do you think you'd be able for it?
