Hi.
Thanks for your query.
Noted the history related to your friend who is male and 38 years old. He is passing black tarry stool, has low hemoglobin of 8 and faints and passes out, had vomiting too; upper GI and colonoscopy are normal.

Since the colonoscopy and Upper GI endoscopy are normal, means he is most probably bleeding from the small intestines.
This can be identified by the following ways:
- Capsule endoscopy can show the bleeding point.
- Diagnostic laparoscopy can show the accumulation of the blood and hence the most proximal part can be the area of bleeding.
- CT scan of the abdomen with intravenous contrast can be of help.
Once the cause is found may need surgical intervention to stop the bleeding. and may need further blood transfusion and oral therapy of iron, folic acid and multivitamins.
