Green stool can have various causes, including the consumption of certain foods, such as leafy greens, or the use of food coloring. It can also be caused by a rapid transit time, meaning food moves too quickly through the digestive system and doesn't have time to be broken down and fully absorbed. In some cases, green stool can be a sign of an underlying medical condition, such as an infection or a digestive disorder, so it's important to talk to your doctor if you're experiencing green stool regularly or if you have other symptoms along with it.
