What is the reason for black sticky stool

Black and sticky stools may be caused by diet, drugs and gastric ulcers.

1. Diet

If the patient eats a large number of darker foods, such as black rice, mulberry, animal liver, etc., it is easy to cause black and sticky stools.

2. Drugs

If the patient's spleen and stomach are weak, and recently a large number of bismuth, iron and other drugs are taken, resulting in a change in stool color, resulting in black and sticky stools.

3. Gastric ulcers

If the patient suffers from gastric ulcers, eating harsh and stimulating foods is easy to cause ulcer bleeding. Iron in the blood combines with hydrogen sulfide in the intestinal tract to form iron sulfide, which may cause black and sticky stools.
