Feces, or stool, is excreted as semi-solid waste by the gastrointestinal (GI) tract after all necessary fluid and nutrients are absorbed from the food we eat. The appearance and texture of adult stool varies and can be impacted by diet, medications, and the functioning of the digestive tract. In particular, the color of stool can at times serve as a gauge of digestive health. Although changes in color may be commonplace and generally insignificant, persistent color change may be indicative of an underlying health issue.
