What's the reason for black shit

summary

I believe you will not be unfamiliar with black excrement. In our life, there are many details of life that can tell us the health of our body. The key is that we must pay attention to these things at ordinary times. So what's the reason for black excrement? Let me tell you.

What's the reason for black shit

First of all, the black stool is usually caused by upper gastrointestinal bleeding. The common bleeding parts include esophagus, stomach, duodenum, even pancreas, biliary tract and other organs. When the red blood cells in the blood decompose in the intestinal tract, they will combine with the sulfide in the feces to form black iron sulfide, making the feces black.

Secondly: if we usually have black stool, it does not mean that there must be bleeding in the digestive tract, because in our life, some foods will also make the stool color black, like the blood and liver of some animals. If we eat this, our stool will also become black.

Finally: if we take some special drugs in our daily life, our patients will also have this problem of black stool. For example, after some Chinese herbal medicines, activated carbon and some drugs for treating ulcers, the stool can be dark red, even tarry.

matters needing attention

What we want to say is that if the patient has taken pig liver or animal blood and the above drugs before defecation, he can be vegetarian for a few days and stop taking the medicine. At this time, he can be examined to see if this situation still exists.
