I had RNY June 23,2017....my experience is: gained 5 to 7 pounds day of surgery....then lost 15 pounds 1st week after surgery, then nothing since....so far. I figure most is surgery fluid and some weight loss from less than normal eating. Waiting patiently and following guidelines ..except need more water, working in that.
