Brown poop? What's going on?

Brown stools may be caused by bilirubin influence, duodenal ulcer, intestinal obstruction and other reasons. Details are as follows:

1. Bilirubin influence

bilirubin is a substance produced by liver metabolism. It will be oxidized into fecal bilinogen after interacting with bacteria in feces in the intestine. Fecal bilinogen will make feces stain brown or dark brown.

2. Duodenal

ulcer occurs when hemoglobin is released after being destroyed. After the action of digestive juice, bilirubin will be changed to brown or tarry color.

3. Intestinal

obstruction Patients with intestinal obstruction will affect bilirubin metabolism in the intestine, resulting in changes in stool color.
