What can i do if i'm super bloated and have sulfur-burps for a couple days now? this happened after two weeks of hospital food so mainly bread and rice if that could've played a role?

Multiple reasons: If you were hospitalized for 2 weeks, it could have led to a stressed stomach causing some inflammation. Also decreased mobility in a hospital environment can contribute to that. Increasing exercise as much as you can, eating healthy food and doing an antacid for a week like famotidine or omeprazole otc can also help. Adding probiotics can also help.
