For the past year, I have had unrelenting gas. At first, it was associated with horrible, almost constant, nausea, where I lost so much weight that I was borderline anorexic. Then, the nausea subsided, and I was finally able to eat. My stool seems normal. Basic tests did not show anything. However, the unusual amount of gas throughout the day has remained the same. It does not seem related to the time of the day or to a particular food group. Any thoughts about what I might try for testing or to remedy this?
