I wish that I read this thread prior to my surgery about the BMs. Today, I had my first one since Sunday night (6/28). It was painful and to top it off there was blood. I ended up having another one and thankfully there was no blood. I had called the on call Doctor after the first one and was told that it could be from the surgery and to watch and see if it continued or not. Thank goodness it was just in the first one. I had the RNY and had exhibited zero pain and didn't have to take any pain meds while in the hospital.
