what does it mean if my poop is green

Green poop can mean several things, most commonly related to diet or how quickly food moves through the digestive system. Eating large amounts of green leafy vegetables like spinach, kale, or broccoli, or foods with green or blue food coloring, can turn stool green due to chlorophyll or dyes. Medications such as iron supplements, some antibiotics, or antacids can also cause green stool. Another reason for green poop is bile, a greenish-yellow fluid that helps digest fats. If bile moves through the intestines too quickly (as in diarrhea), it can make poop appear green because it hasn't had time to change to the usual brown color. Green poop can sometimes indicate bacterial (Salmonella, E. coli), viral (norovirus), or parasitic infections that speed up digestion, but this is less common. If green stool persists, or if it comes with other symptoms like abdominal pain, weight loss, fever, vomiting, or blood in stool, medical advice should be sought. In summary, green poop is often harmless and related to food or medications, but can occasionally signal an infection or digestive issue.
