The severe gas you are experiencing, medically referred to as dyspepsia, is a classical symptom of gallbladder stones (cholelithiasis).
Next Steps
There is no definitive medical cure for gallbladder stones; surgical removal is the only treatment option. Surgery can be performed by open, laparoscopic, or robotic technique. Postponing surgery may lead to serious complications such as gallbladder perforation, which can be life-threatening, or, in the long term, increase the risk of gallbladder cancer.
