Stomach bile is typically green or yellow.
Understanding Bile Color
Bile, produced by the liver and stored in the gallbladder, is a digestive fluid. It plays a key role in breaking down fats in the small intestine. The color of bile is primarily due to the presence of bilirubin, a yellow pigment produced during the breakdown of red blood cells.
Here's a breakdown:
- Green: The green hue often comes from biliverdin, a precursor to bilirubin.
- Yellow: This is the more commonly seen color of bile, caused by bilirubin.
When is Bile Seen?
Bile is usually not seen in normal circumstances. However, you might notice it when:
- Vomiting on an empty stomach: If you haven't eaten recently, vomiting may bring up bile, resulting in a yellow or green appearance.
- Experiencing bile reflux: This condition occurs when bile flows backward into the stomach and esophagus, potentially causing vomiting or other symptoms that may include the expulsion of yellow- or green-tinged liquids.
- Illness: Specific illnesses or digestive issues can result in the production or regurgitation of bile.
Table: Bile Color and its Source
| Bile Color | Primary Cause |
|---|---|
| Green | Presence of biliverdin |
| Yellow | Presence of bilirubin |
Key Takeaways:
- The color of bile is usually green or yellow because of pigments produced during the breakdown of red blood cells.
- You might see bile during vomiting, particularly on an empty stomach, or with bile reflux.
- Bile is a digestive fluid produced by the liver and stored in the gallbladder.
