Hello, Thanks for your query. Bile — a fat-digesting yellow-green fluid that s secreted by the liver and stored in the gallbladder — can also cause green poop. As bile pigments travel through your gastrointestinal tract, they are chemically altered by enzymes, changing the pigments from green to brown, Your poop may be green if you eat a lot of green vegetables, such as spinach and broccoli, because these foods contain large amounts of the green pigment chlorophyll. green poop is an indication of a health issue I do hope that you have found something helpful and I will be glad to answer any further query. Take care
