Re: 5days post op
This doesn't sound normal at all! You should call your doctor. I developed diarrhea after my hysterectomy too but I don't recall it being that quickly post-op - don't remember. I also had some nausea (no vomiting though) but I think that was from the loss of hormones from the removal of my ovaries. The diarrhea continued for FAR TOO LONG. My surgeon (who'd been my gynecologist for 20 years) refused to see me when I called his office. The diarrhea gradually improved but at 10 months or so still had not totally resolved. I finally saw a gastroenterologist and still never got a diagnosis.
You could very well have a hospital acquired infection. They're pretty common. Let us know what you find out.
