The term "green poop" refers to feces that are colored green. This can happen due to various reasons, such as the consumption of certain foods (like spinach or food coloring), bile not being properly broken down, or digestive issues. While it may sound concerning, green poop is often a normal variation of stool color that can result from dietary choices.
The word "poop" is derived from the Middle English "poupen," which means to break wind or expel waste. The word "green" comes from the Old English "grēne," which is related to growth and freshness, as it describes the color typically associated with nature.
