The 22-year-old actress is believed to have suffered from the condition for while, with one attack on the set of Corrie proving so severe that filming was halted until she recovered.
As a result, Helen has asked for immunity from any challenges which may trigger such an episode, according to The Mirror.
Her request apparently hasn't gone down well with fellow campers. One nameless contestant is quoted as saying: "It wouldn’t be fair on everyone else as producers wouldn’t want to take any chances.
"You have to question how many tasks she could miss."
An insider retaliated: "People need to give her a break. A number of celebs in the past – such as Gillian McKeith – have been allowed to be exempt."
However, a show spokesperson insisted: "Helen is not excluded from taking part in any activities in the jungle."
Producers have been known to occasionally hand out byes to contestants, while several stars such as Sinitta and Katie Price have freaked out and even quit during the more claustrophobic tasks.
Colin Baker, David Haye and Linda Robson are among the other famous faces joining Helen in the new series, which begins on Sunday at 9.00pm.
