### Human:\nhow quickly can one get diarrhea after eating? . my spouse says that if i have diarrhea i should try to recall what i ate the day before. i think one can get diarrhea the same day within hours or even minutes after eating something that doesn't agree with me. thank you!\n\n### Assistant: hi and yes its all done to what we eat and the way it affects our stomach if what you eat was a very hot chilli or curry this could go straight through you if your stomach cant stand it why other things may take longer. good luck
