Green stool w/grass
The color of stool varies with foods, speed of emptying of the GI tract, medications & supplements
ingested, gut flora (unique for each individual), additives (like blood), subtractions (like absent bile
), infection, inflammation
, & other factors.
Consider what you ate in the last few days, but if the green color is unusual for you & persists or is accompanied by other symptoms, see your doctor.
