Explanation
Bilious vomiting is when the vomit has a greenish color because it contains bile, a digestive fluid produced by the liver. This type of vomiting can be a sign of a blockage in the intestines, especially in newborns, and may require immediate medical attention.
Nonbilious vomiting does not have this green color and can be caused by a variety of other reasons, such as infections, feeding problems, or stomach irritation. It is generally less concerning than bilious vomiting but should still be monitored, especially in infants.
Key Differences:
- Color: Bilious is green; nonbilious is not.
- Cause: Bilious may indicate a blockage; nonbilious can have many other causes.
If you or someone you know is experiencing vomiting, especially if it is green, it is important to seek medical advice to determine the cause and appropriate treatment.
