I have had a Nissen Fundoplication, twice. The last one was about two years ago. I know this can cause problems with gas bloat but this is really painful. My stomach gets hard distended and I have to lay down on my left side in the fetal position to get the gas to pass. Sometimes the gas affects my lower back and I am in so much pain I can barely stand. I am so tired of laying on bathroom floors. I have been tested for celiac, I've had breath test for small intestine bacterial overgrowth which was positive for intestinal Methogen Overgrowth but the treatment did not work. The antibiotics just made me feel awful. I do not drink carbonated beverages. I've tried the IB Guard, I've changed my diet multiple times. I eat healthy. I have an active lifestyle. Nothing is working! My doctor seems convinced a diet change will help but I've tried. My doctor ignores me having to lay on my side to pass the gas. There has to be something else going on. My gallbladder was removed 8 years ago. I am a 29 year old female, 3 years post hysterectomy, I only have my right ovary. This painful boating is affecting my job, my social life, and my mental health. Any advice would be helpful.
