No Dr. did not tell me what caused it. I did take antifungal w/ band in. I couldn't eat initially and after one round I couldn't even hold down water. Dr. said it could be unbuckled or it could be taken out. I had been in the week before for an EGD due to pain which is when the yeast infection was found.and was put on the antifungal. The antifungal hadn't worked and when I asked why, Dr. response was, "I'm not a GI specialist, I don't know." and said I could have until the morning to decide, but direct admitted me so I wouldn't dehydrate. I was not getting informed care and knew it wasn't going to get any better as I had been at this process for a year and a half. I opted to have it out and ended up having to take 2 more rounds of antifungal and have fluid removed from my incision site. I had so many unanswered questions and couldn't get physician to even see me in the hospital. Finally a bariatric nurse came in as I kept insisting that I talk to someone and the nurse pretty much told me my body was rejecting the band and after our talk and seeing that this nurse had had experience in bariatrics for approx. 7 years I made the decision to have it out. I haven't been back to operating physician. But did have to have a ct scan on belly due to enormous protrusion on belly at incision site. Thankfully a new bariatric surgeon had moved into my community that I went to to have the fluid removed from my incision site. I've looked online to try and find information on yeast infections in the esophagus and I haven't found anything yet that relates it to lap band surgery. Emotionally/mentally I've had a difficult time and am still trying to lose weight, but not considering surgery at this point.
