Green Vomit in Terminal Cancer: Causes from Bile Obstruction to Medication Effects

Green vomit in advanced cancer patients can arise from:

1. Bile obstruction – Tumors block bile flow; bile backs up into stomach.
2. Liver damage – From cancer or chemo/radiation; impaired bilirubin processing.
3. Intestinal obstruction – Tumor blockage causes bile/fluid buildup.
4. Medication side effects – Chemo drugs alter digestive function.
5. Infections – Weakened immunity predisposes to bacterial/viral GI infections.
6. Electrolyte imbalances – Dehydration, malnutrition, prolonged vomiting.

Medical evaluation is essential to identify and manage the underlying cause.
