Welcome to the ehealthforum and I am really glad to help you out. The green or the bilious vomiting indicates the presence of bile in the vomitus. Bile is the juice which is produced by the liver and is green in colour. Bilious vomiting can happen because of the presence of bile in the stomach which can induce gastritis resulting in the vomiting.
It can also occur if thereâs some obstruction in the intestine. You might need further investigations like an upper GI endoscopy, ultrasound & x-ray abdomen to look for the cause of the same. Please do consult a surgeon as it is not possible to diagnose online. I sincerely hope this helps. Take care
