Why is my poop blue?

The color of your poop can vary depending on a number of factors, such as your diet, hydration levels, and any medication or supplements you may be taking.

If your poop is blue, it may be caused by certain foods or drinks that contain blue or purple pigments, such as blueberries, blackberries, grapes, or purple food coloring. These pigments can pass through your digestive system and mix with your stool, resulting in a blue color.

However, if your poop is consistently blue or you experience other symptoms such as abdominal pain, diarrhea, or fever, you should consult a gastroenterologist as it could be a sign of an underlying medical condition such as a digestive disorder or a gastrointestinal infection.

Foods that can make your poop blue

  1. Blueberries: These nutritious berries are packed with antioxidants and can turn your poop a shade of blue.
  2. Blackberries: Similar to blueberries, blackberries can also give your poop a blue hue.
  3. Beets: Eating beets can cause your poop to turn reddish or purplish, which can sometimes appear blue.
  4. Grape juice: Drinking grape juice can cause your poop to turn a bluish-green color.
  5. Purple carrots: These colorful carrots can contain pigments that can turn your poop blue or green.
  6. Artificial food coloring: Certain processed foods, such as candies, cereal, or drinks that contain blue or purple artificial coloring may turn your poop blue.
  7. Red cabbage: Eating red cabbage can give your stool a blue or green tint, depending on how it’s cooked.
  8. Plums: This fruit can cause your poop to appear blue or green.
  9. Froot Loops cereal: The artificial colors used in this breakfast cereal can make your poop blue or green.
  10. Spirulina: This blue-green algae is often used as a dietary supplement and can cause your poop to turn green or blue.

Remember that food colorings can pass through your digestive system and mix with your stool, resulting in a change in the color of your poop. However, if you notice any unusual changes in your bowel movements or experience other symptoms, consult a gastroenterologist to rule out any underlying health issues.
