When you have diarrhea


Diarrhea is the passage of loose or watery stool. For some, diarrhea is mild and will go away within a few days. For others, it may last longer. It can make you lose too much fluid (dehydrated) and feel weak. It can also lead to unhealthy weight loss.

The stomach flu is a common cause of diarrhea. Medical treatments, such as antibiotics and some cancer treatments can also cause diarrhea.
