What is the color of black?

The reasons why stool color is black generally include excessive consumption of animal internal organs, gastritis, gastric ulcer, etc. Details are as follows:

1. Excessive consumption of animal internal

organs contains a large amount of iron. If a large amount of animal internal organs are eaten, they will turn black after being decomposed by bacteria in the intestinal tract. When mixed with stool, it will cause stool to turn black.

2. Gastritis

infected with Helicobacter pylori may cause gastritis, which will weaken the digestive ability of the stomach and make it unable to digest food completely and excrete brown and black stools.

3. Gastric ulcer

If due to genetic factors, mental factors, etc., gastric mucosal ulcer may cause stomach bleeding. Blood and stool are discharged together, which will make stool appear black.
