Vomiting bile, a yellow-green fluid, often signals a problem in the digestive system such as an intestinal blockage, bowel obstruction, or bile reflux. In newborns, it can be especially serious and may point to conditions like malrotation or volvulus that require urgent medical care. In adults, causes may include gallbladder issues, ulcers, or complications after surgery.

Because vomiting bile can indicate a medical emergency, it should never be ignored. Symptoms like severe abdominal pain, dehydration, or repeated vomiting warrant immediate evaluation by a healthcare provider.

Explanation

Vomiting bile, which is green or yellow, can be a sign of a blockage or problem in the digestive system. In newborns, this is often considered serious and needs quick medical attention. Some causes include:

  1. Blockages in the Intestine: This can happen when something is blocking the path in the intestines, preventing food and bile from moving through.

  2. Malrotation: This is when the intestines are not in the right position, which can cause a blockage.

  3. Intestinal Atresia: This is when a part of the intestine is closed or missing, causing a blockage.

In older children, vomiting bile might happen after a long period of vomiting when the stomach is empty.
