What is the term for the frequent passage of liquid stools?

Diarrhea is characterized by the frequent passage of liquid or loose stools. This condition can occur due to various factors, such as infections, dietary changes, or underlying health issues, and may lead to dehydration if not managed appropriately. The key aspect of diarrhea is the consistency and frequency of the stool, which distinguishes it from other gastrointestinal issues.

In contrast, constipation refers to infrequent or difficult bowel movements, fecal impaction involves a severe form of constipation where stool becomes hard and lodged in the colon, and colitis is an inflammation of the inner lining of the colon, which can sometimes lead to diarrhea but is not defined by it. Understanding these distinctions helps clarify why diarrhea is the correct term for the condition described in the question.
