I had my first gallbladder attack about 6 months after my surgery. It was while on vacation and I attributed it to indulging too much food during breakfast. It was the first time I had any problems with food and throwing up after 5 hours of extreme stomach and pain. It was the worst pain and I never ate sausage gravy again. I suffered from an attack about once a month from that point on (always thinking it was band related and food related even though I am the most strict rule follower in the band world) Until December where I had a 5 day attack that resulted in 5-7 hours cycles of extreme pain resulting in vomiting. We thought it was swelling from band, virus, etc...finally saw a surgeon who was filling in for my actual weight loss surgeon and his first questions were about right side pain, back pain, after eating, etc....he sent me for a Hida scan and sure enough my gall bladder was not "squirting" correctly (his term). I had my gall bladder out before Christmas and I have not had one single episode again. Unfortunately after doing some research prior to my gall bladder surgery it is very common for weight loss patients to have gall bladder issues as well. Don't suffer through the pain, go to the doctor! Good luck!
