<s>[INST] I am 21 years old, male, 240lbs. I have been binge drinking heavily for the last 2-3 weeks. This morning I threw up about 1-2 cups of dark red blood. The area where my liver is located still has a constant dull ache. What should I do? I would prefer to not go to the hospital, but I am unsure if this is serious or not. [/INST] Hi, dairy have gone through your question. I can understand your concern. Vomiting of blood is a serious problem. You may have esophageal varietal bleeding due to portal hypertension or YOY may have some other cause. You should go for upper GI endoscopy, ultrasound abdomen and liver function test. Search for the cause and take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health. </s>
