大便有d好似黑芝麻既野,係咪生蟲?

Certain types of food and medications can give you black stools, like iron supplement, bismuth medicines, or blueberries.

Digested blood is usually from bleeding in the upper gastrointestinal tract from esophagus, stomach, or duodenal. Bleeding in your gastrointestinal tract may be a sign of various serious problems especially if your stool has a foul-smelling odor to it. It may be signs of gastrointestinal ulcers, tears, or even certain types of cancer. Prolong bleeding may lead to hypovolemic shock, and you do not want to experience that. My recommendation to you is to go see a doctor.

Hope this help.
