What symptom can you still have when pulling black stool

First, we have black stool, which does not mean that there must be bleeding in the digestive tract. Some foods or drugs can also make the stool black, such as some Chinese herbal medicine, activated carbon and ferrous carbonate, or even some drugs for treating ulcers, or eating too much pig liver and animal blood, etc.

Second, the black stool is usually caused by upper gastrointestinal bleeding, including esophagus, stomach and duodenum, or pancreas and biliary tract. When the red blood cells in the blood decompose in the intestinal tract, the iron contained in the red blood cells will blacken the feces under the action of gastric acid and intestinal Escherichia coli.

Third: if we want to know whether the black stool is related to gastrointestinal bleeding, we should do stool occult blood test. If the patient has eaten the pig liver and animal blood before black stool, he can be vegetarian for a few days and stop taking the medicine, and then accept the examination. If he is diagnosed with gastrointestinal bleeding, he should be treated as soon as possible.
