Hi
. Maroon-colored blood or brown blood usually suggest that the blood is coming from the lower part of the GI tract (large bowel or rectum).
Hemorrhoids and diverticulitis (inflammation of an abnormal pouch in the colon) are the most common causes of lower GI bleeding
Other causes are:
Anal fissures
Diverticular bleeding Intestinal infection (such as bacterial enterocolitis) Vascular malformation Inflammatory bowel diseaseHe need:
Blood studies, including a CBC ColonoscopyGastroscopyor EGD Barium studies Stool culture X-rays of the abdomenSonogram abdomenSo I advice him to consult gastroenterologist soon.
Hope this helps
