Hi, I ve been having stomach problems for quite some time now. Lately, the problem is I have hardly felt hungry, and when I do eat I get this terrible gas and I also feel very nauseous. I haven t thrown up, but that s mostly because I hold it in or because I ve hardly eaten. I don t know what the problem is, but I also know I have a sharp pain on right side of my abdomen. Also, I sometimes feel better after I burp. If it helps your evaluation, I am a vegetarian. Help!
