[|Human|] My husband has vomited which was dark green/ black. He has metastases on his liver and lungs. Should I ring a doctor immediately? He feels ok but nauseous when he stands up or tried to eat and just wants to sleep in bed at home not go off to hospital.hes already been seen by the doctor today.
[|AI|]  Hi, Thanks for writing in. Vomiting that is green or black is most likely to be due to bile or altered blood. It is important to consult your doctor and get him treated for the concern. Liver and lung metastases with a primary cancer elsewhere is advanced disease. Such condition can cause complications such as bleeding inside the gastrointestinal tract or vomiting bile due to inability of bile getting cleared the normal way. It will help to take him to a medical facility urgently and get an endoscopy done should there be a doubt of bleeding from the inside of stomach. This needs early diagnosis and stabilization. Please do not worry.
