 [ Symptoms ] i was diagnosed with influenza a ten days ago i still feel nauseous and have loose bowel movements is this normal [ Disease ] this is a great question and i am so glad you asked many people associate gastrointestinal upset nausea diarrhea with the flu influenza but actually the true flu does not usually produce any of these symptoms sometimes people refer to the stomach flu  which is actually a condition called gastroenteritis  the nausea and diarrhea you are experiencing likely are caused by something other than influenza a have you by chance taken antibiotics recently if so that class of medications can cause gastrointestinal upset this condition usually gets better after you finish the course of antibiotics you also should consider eating yogurt or taking a probiotic to help with antibiotic associated diarrhea be sure to drink plenty of water whenever you have diarrhea    and wash your hands thoroughly in case you are carrying a bug that can be passed to others if the diarrhea does not clear up within 14 days or so another trip to the doctor is in order to try to figure out what is causing the problem wishing you well
