Only rarely does stool color indicate a potentially serious intestinal condition. Stool color is generally influenced by what you eat as well as by the amount of bile — a yellow-green fluid that digests fats — in your stool.
As bile pigments travel through your gastrointestinal tract, they are chemically altered by enzymes, changing the pigments from green to brown. Consult your doctor if you're concerned about your stool color.

Here, doctors explain, specifically, the top seven reasons your poop might have a greenish color—and what you can or should do about it. If you've recently been ill and taken an antibiotic, it's not uncommon to see a color change in your stool, says Eswaran. It's also not uncommon to have antibiotic-induced diarrhea, which could cause your stomach to hurt. Luckily, this should clear up within a few days, after you complete your course of the medication.
Not dissimilar to the reason antibiotics do a number on your poop, bacteria invading the GI tract could cause a green tinge to your stool. Diarrhea itself always increases the odds of green stool, too. Food moving through the body too quickly may not have the necessary time for bile to break it down, which could cause your stool to remain a greenish color instead of brown. Heidi Moretti, RD , a dietitian focusing on functional nutrition, says it's not uncommon to see green stool if you have other GI issues, especially ones that cause diarrhea.

Blueberries, grapes, and red wine, for instance, can result in a dark green-blue stool. Purple or red and blue food coloring in drink mixes, grape Kool-Aid and soda, frozen ice pops, cake icing, blue Gatorade, packaged fruit snacks, licorice, and grape-flavored Pedialyte can also cause dark or bright green poop. These food dye colors are often used during holidays such as Easter, Independence Day, and Halloween.
As bile makes its way through the small intestine to the large intestine via the bile ducts, it progressively changes color from green to yellow to brown. This is due to the action of bacteria in the large intestine acting on bile salts. In some cases, consuming lots of coffee, jalapenos, chili pepper, and alcohol can have a laxative effect, causing foods to pass through the intestines faster than normal called decreased transit time and before stool change color from green to brown.
Taking iron supplements can change the color of your poop to dark green or black. Juicing or going on a juice cleanse will also up your intake of chlorophyll and, in turn, increase the likelihood of green-tinged stools.
If you experience green stools during a colon cleanse, it may be due to food rushing through your intestines too quickly to allow bacteria to give your stool its characteristic brown color. A high-fat diet, like the keto diet , may give your poop a bright green hue. With a high-fat intake, your body produces more bile to digest these fats and excess green-colored bile may find its way into the toilet bowl. Green stool can occur during pregnancy. Some women get it in the earliest weeks of their pregnancy, sometimes even before the BFP "big fat positive" on the pregnancy test.
Other women get it because they take prenatal vitamins which contain a higher dose of iron than the typical multivitamin or iron supplements. Green stool can also happen during the third trimester. Some women get loose green stools during late pregnancy as food moves rapidly through the intestines.
An infant's first bowel movements are typically green-black in color. Dark green or green black poop in babies may be caused by iron supplements and iron-enriched foods, such as baby formula. Green poop in breastfed babies particularly "EBF" or exclusively breastfed babies could also be a sign that the baby is getting too much low-calorie, low-fat foremilk the milk that comes first in a feeding and not enough hindmilk, which is higher in fat.
It could mean that the baby isn't feeding long enough on each breast or draining the breast effectively or that there is an oversupply of breast milk. A lactation consultant may be able to help identify the issue. Kids often eat foods that contain food dyes, including green, purple, blue and yellow, or red and blue coloring. Chewing on green or purple crayons can also change the color of stools. Diarrhea decreases bowel transit time, so any condition that causes diarrhea can result in a green stool, including:.
A rare but serious cause of green stool in kids and adults is poisoning by chemicals such as the pesticide paraquat. Green stools accompanied by visible mucus may signal irritation or inflammation in the lining of the intestines.
