What causes brown stool?

If the stool is brown, it may be caused by diseases such as duodenal ulcer, gastric ulcer, and gastric mucosal prolapse. In daily life, you should also pay attention to the shape of the stool, because in many cases the stool can reflect the health of the body.

1. Dark yellow stool: This is often seen in hemolytic jaundice, which is jaundice produced by massive destruction of red blood cells. It is often accompanied by hemolytic anemia, which can be caused by congenital red blood cell defects, hemolytic bacterial infection, malignant dysentery, blood transfusion with the wrong blood type, poisoning by certain chemicals or toxins, various immune reactions (including autoimmunity), etc.

It includes duodenal ulcer, gastric ulcer, antral gastritis, gastric mucosal prolapse, esophageal varicose vein bleeding in liver cirrhosis, etc. However, if you eat too much meat, such as animal blood, liver, spinach, take oral iron, bismuth, activated carbon, etc., the feces may also be black, which should be distinguished.

3. The stool is grayish white, and the whites of the child's eyes and skin are yellow. This may be due to bile duct obstruction, thick bile, or hepatitis.

4. Black stools may be caused by bleeding in the stomach or upper intestine or by taking iron supplements to prevent and treat anemia.
