Diatrrhea after TIF

Hi. I had the TIF procedure two weeks ago and had only had one bowel movement since the surgery and then I got a really bad case of diarrhea yesterday. I constantly feel nauseous, especially after I eat or drink anything, which hasn't been much at all since my surgery. As I am still pretty much on a liquid diet with some soft foods, I have been drinking ginger drinks to help with nauseousness. Before the surgery I was nauseous often, so I took ginger candy but since I can't really have solids right now, I have been trying the ginger drinks...it works immediately, but unless you are continuously drinking it, its effects fade.
