personally i wudnt worry, as theres no real cure for it.. stressing with agrivate and smasm the bowel, i suffer with it loads… u may have the shits after ur op, i was dreadful after my c-section… depends on how badly u suffer with it, but it wont effect ur operation at all babe and ur not on meds for it. its one of those things thats mainly brought on by stress thats all. ive been literally doubled over in pain with it!! or if someone upsets me i will literally have the shits within the next 10 mins, its horrible hahahh xxx urs will be because ur worrying about ur BA… if uve got no bleeding when u poo, no water infection, fever, vomiting etc then its defo irritable bowel syndrome. relax, eat healthy and stop worrying and it will massivley improve xxxxx
