OK, it had to happen sometime... Crunch time came and I finally managed to pluck up the courage I required to express my conscerns to my mother. Seems that I'd been making a fuss about nothing. Apparently the doctor said she has an acute e-coli infection. I was on the right track so I'm slightly pleased with myself about that, don't worry though, I'm not running for a doctorate just yet :P
Probably more so than anything, I was pleased to find out that she was thrilled that I'd been trying to get help from people like yourselves which put me much more at ease for the rest fo the conversation.
So there ya have it, e-Coli, I hope that helps.
