Acute diarrhea is a type of diarrhea that comes on suddenly and may last for a few days. It's often caused by dietary indiscretions, infections, or stress.

Chronic diarrhea persists for an extended period, typically more than 2-3 weeks. It may indicate an underlying medical condition or a long-term dietary issue.

Small bowel diarrhea is characterized by loose, watery stools and may be accompanied by gas and abdominal discomfort.

Large bowel diarrhea is associated with frequent, urgent bowel movements and may contain mucus or blood. It's commonly linked to conditions such as colitis or cancer.

Hemorrhagic diarrhea contains fresh blood, which can be a sign of a serious underlying condition, such as parvovirus infection or a foreign body obstruction.
