Diarrhea
If you are susceptible to digestive complaints, then you may develop diarrhea after getting the flu. However, diarrhea is not a well-known symptom of the flu. Diarrhea can make you feel weak and tired, so it is important to keep you hydrated. Diarrhea induced by flu often clears up in a few days time. Keeping yourself hydrated and taking plenty of rest is the key to treat flu-induced diarrhea.
