What's wrong with the dark shit?

The color of stools is deeply considered to be caused by dietary factors, drug factors and disease factors.

1. Food

If you eat too much black food recently, such as black candy, dark chocolate, etc., it may affect the color of stools and cause the color of stools to deepen.

2. Drug factors

If you take iron recently because of physical reasons, iron will combine with hydrogen sulfide in the intestine to form iron sulfide, resulting in dark stools.

3. Digestive

problems.
