For a month or so my wife has been experiencing severe bloating, flatulence and diarrhoea. We thought we had it pinned down to chocolate and/or fruit juice, only now everything seems to be triggering it and she has just had a really bad bout of constipation. Everything she has eaten in the last week has set off the bloating and she is now feeling weak and nauseous, though the constipation seems to have lessened slightly and she is passing the occasional ribbon shaped stool.Does this ring true for being IBS? Is it normal for it to ramp up and seem to just be triggered by everything despite us constantly cutting out more and more foods? Is her feeling progressively worse the longer the 'bad patch' continues also to be expected if it is IBS?
