What is diarhhia?

Answer 1

Diarrhea is the term for fecal matter which contains more liquid than that of most fecal matter. The most common reason for one to have diarrhea is that the digestive system is not absorbing enough moisture from the stool, causing it to leave the body in a very runny form. Often this happens when one is ill, or if the body has consumed an unfamiliar food or medicine.

If you mean diarrhea, it is also called loose motion of the bowel. Water level is more than normal. Body secretes more water into the digestive tract to expel the unwanted excretory materials. This happens when there is bacterial infection in the gastrointestinal tract. Diarrhea always follows indigestion or constipation.
