If my stomach doesn't hurt, it's diarrhea. What's going on?

It may be due to indigestion, because the food eaten has not been properly digested and then excreted, it will show diarrhea. Or it may be due to the dysfunction of the gastrointestinal tract itself, and then the secretion of intestinal secretions is excessive, it will also show diarrhea. It is best to check stool routine, see if there is no intestinal infection, if there is a virus or bacterial infection, you can symptomatic use some antibiotics, or antiviral treatment, and then pay attention to whether it is because of eating food that is not easy to digest, this situation should pay attention to adjusting diet.
