Green Stool – Causes & When To See The Doctor

Green stool

Green stools are frequently the result of an excessive intake of leafy, green foods. The green hue is produced by chlorophyll in plants. Alternatively, youngsters may have green stools following the consumption of artificially colored frosting at a birthday party.

Green poop is almost often caused by certain items in a person’s diet. Individuals who do not consume a lot of greens or food coloring, on the other hand, should exercise caution, as green poop can indicate a more serious condition.

Causes of Green Stool

A common cause of green poop is the type of food and drink a person takes. Examples of such food include:

  • Blueberries or other blue or purple fruits and vegetables.
  • Green fruits such as avocados, green apples, and honeydew melon.
  • Hemp seeds.
  • Herbs such as basil, cilantro, and parsley.
  • Matcha (powdered green tea).
  • Pistachios.

Other possible causes of green stool include:

  • Bile pigment: Stool may be green due to the presence of bile pigment. If food moves too quickly through the intestine, bile pigment cannot break down sufficiently. One potential cause of this is diarrhea.
  • Antibiotics: Antibiotics can change the types of bacteria present in the gut. Because bacteria influence the typical color of poop, a change in bacteria may mean a change in stool color, often to green.
  • Certain medical procedures: For instance, a person whose body rejects a bone marrow transplant may develop graft-versus-host disease. Diarrhea and green stool are symptoms of this condition.
  • Parasites and bacteria: Certain pathogens can cause poop to turn green, including the Salmonella bacterium, the water-based parasite Giardia, and norovirus. These unwelcome guests can cause the guts to work faster than usual, impacting stool color.

Infants might have green stool as a result of:

  • Not finishing breastfeeding entirely on one side, thus missing some of the high-fat-content breast milk, which affects the digestion of the milk
  • Protein hydrolysate formula, which is used for babies with milk or soy allergy
  • Lack of normal intestinal bacteria in breast-fed infants
  • Diarrhea

When To See The Doctor

As mentioned, colorful poop isn’t all that unique and is usually connected to something you ate. Think back on what passed through your lips and you’ll probably come up with a simple (and perhaps even regrettable) reason for the burst of color.

That being said, oddly colored poop might indicate something that needs attention — particularly if it lingers or comes with symptoms such as abdominal pain, weight loss, bleeding, fever, and vomiting. Pale poop or blood-tinged stool is of particular concern, too.
