true "traveler's diarrhea" is a bacterial infection often due to enteric e. coli but parasites and viruses can cause diarrhea too (heard about those cruise ships? ). i don't think this had anything to do with your nexium. the advice that you can "eat anything" was not intended to say that nexium prevents food-borne pathogen infections.
can simply eating fresh lobster while on nexium cause traveler's diarrhea? . i have been on nexium for several years now. the doctor said i could eat anything i wanted. i recently tried a fresh lobster for the first time. the next day i had explosive diarrhea. it has not stopped for four days now. i do typically drink nothing but caffeine (coffee and tea) and today (day 4) i became feverish. luckily i have experienced dehydration before and recognized the symptom as it related to diarrhea. the fever subsided with high intake of gatorade.
