I had a gastric bypass (RNY) six years ago and had done wonderfully. About a month ago, I started having stomach pains and began throwing up any dense foods. This has continued for several weeks and now my belly is extremely swollen, I have uncomfortable gripy, pin prickly sensations in my upper bowels, and despite throwing up, I have gained ten pounds during this time. I originally lost 215 pounds and have successfully kept the weight off until this episode.
