A member asked:

Im vomiting blue bile and have not eaten or drank anything in 48 hours due to nausea. before it was blue, it was green.

A doctor has provided 1 answer

Look at what you ate: Blue is not a color created by the body. When vomit is blue, the source is something that was eaten. Stomach contents are white to yellow. As you get deeper into the intestines, bile is green to dark green. Then the vomit gets to look like liquid poop.
