Background on this girl: 17yo, life long sufferer of constipation, eats oily food, avoids water and will only eat fruit given by her grandmother. She's on Movicol x4 a day, Concerta, and a few others I forget now..
Being a 17yo is borderline adult, old enough to be responsible, but still young enough to be impressionable. I tell it straight. She is eating shit food. It's no wonder she's got diarrhoea and tummy pain.
