Hi, Dyspepsia or indigestion is the condition that gives the symptoms of the fullness of stomach after taking some food, sometimes it can be associated with infection, one more condition is there and that is hyperacidity and it can be with dyspepsia and infection. First thing is, taking care in diet, avoid heavy meal, avoid oily food, fat-containing diet, have vegetable diet, avoid spicy food. Just for safe side or on tentative basis Metronidazole and omeprazole can be tried. Hope I have answered your query. Let me know if I can assist you further.
