It is likely that you could pass a green stool during pregnancy. Though it sounds a bit gross, there is nothing to worry about it. Your stools contain many things, such as water, indigestible fiberiInsoluble fibers that cannot be digested and hence are passed whole through feces. , protein, fat, cholesterol, intestinal mucusiEssential mucosal lining in the intestine to protect the intestinal lining from bacteria. , and bacteria (1). As pregnancy causes alterations in the digestion process, you may notice color changes in stool too.

What Causes Green Poop During Pregnancy?

One reason could be that the food has passed quickly through the digestive system, not giving enough time for the bile to break it down completely. This might give a green color to the poop as the microbes did not have enough time to change the bile and feces to brown (2). Green poop could also be due to:

General causes

  • Green foods: Consuming lots of green vegetables is a part of a healthy pregnancy diet, and is essential for maintaining gut health. The green pigment, chlorophyll, found in these vegetables could give it a green color. Also, foods that have green dye or added green color may result in green poop (3).
  • Purple foods: Foods such as grapes and eggplant may also cause a change in poop color. Purple gets in contact with bile juices and turns into another color.
  • Laxatives: If you are on laxatives for constipation, there are chances that the stool might turn green as the food passes quickly through the digestive system. There will be little time for the bacteria and bile to act on the food, making the poop green.
  • Iron-rich foods or supplements: You may be taking more iron-rich foods and supplements to stay away from anemia during pregnancy. Any excess or unused iron could make the stool look green or even very dark colored (4).

  • Antibiotics: To boost your immune levels, your doctor might suggest some medications for regulating your health. They could also cause green pee or poop during pregnancy.

The above is the benign list of causes for green poop. A few medical conditions may also lead to unusual changes in the appearance of the poop, which could include a change in the color of stool to green.

Medical causes

  • Celiac disease: Celiac disease is an autoimmune diseaseiThe failure of a body’s defense mechanism to recognize its cells, thus attacking them. that may develop when gluten (a protein present in wheat, barley, and rye) causes immune reactions. It could lead to inflammation of the small intestine, thereby hindering nutrient absorption (5).
  • Pseudomembranous colitis: It is an inflammatory condition of the colon due to the overgrowth of the bacteria Clostridium difficile (or C. Diff. Colitis) that throws everything off balance. It could be a result of taking certain antibiotics and medications (6).
  • Giardia: It is an intestinal parasitic infection that you could contract by consuming contaminated water and food. In most cases, it clears on its own, and in some severe cases, you might need antibiotics (7).
  • Irritable bowel syndrome: Here, the muscles that help the food move through the large intestine either contract actively or for a longer time. It, therefore, might cause gas, diarrhea, and bloating, which could change the appearance of the poop (8).
  • Crohn’s diseaseiA chronic inflammatory disease that causes inflammation of the gastrointestinal (GI) tract that extends from the stomach to the anus. : This condition might affect a small part of the intestine and colon, thereby changing the digestion process (9).
  • Ulcerative colitis: It is a bowel disorder that affects the inner lining of the colon and rectum, and may cause inflammation and ulcers in the tract, leading to digestive issues and abdominal cramps (10).
  • E.coli: Found in feces of humans and animals, this bacterium spreads when you consume contaminated food and water. Undercooked meat could also be a source of this bacteria. Consuming such foods could lead to abdominal cramps and diarrhea.
  • Salmonella food poisoning: Another bacterium, salmonella, is contracted through contaminated food and water and could cause diarrhea and abdominal cramps. It also spreads through the consumption of undercooked poultry meat.

  • If you are on antibiotics, talk to your doctor and change the dosage or medicine if necessary.

Cholestasis of pregnancy is a liver condition that slows or stops the regular flow of bile from the gallbladder, thus affecting your health during pregnancy. It makes the poop light in color (14).

5. How can I prevent green poop during pregnancy?

Most of the time, green poop is a side-effect of dietary changes or consuming prenatal supplements during pregnancy (3) (4). If it is diet-related, you will notice a color change once you stop consuming that food. If it is supplements related, you may consult your doctor.

Probiotics may also be recommended to restore healthy gut bacteria and aid digestion.” However, if infection-like symptoms accompany it, a proper treatment plan for the specific cause must be undertaken after consultation with the doctor.

A change in poop color to green does not occur in all women and is not a major cause of concern. Green poop during pregnancy could be caused by something as simple as eating too many green leafy vegetables, iron-rich food, antibiotics, or foods containing green food color. However, in rare cases, certain severe medical conditions, including IBS, celiac disease, or infections, could also be the underlying cause.
