What's the reason for laxity and blackness

summary

We all know that gastrointestinal bleeding can cause bloody stool. In fact, melena is also a kind of bloody stool. Only when the blood from the digestive tract stays in the blood for a long time, it causes the color of stool to turn black. Generally, upper gastrointestinal bleeding is more likely to cause melena, such as stomach and duodenum bleeding. If it's bleeding in the lower digestive tract (jejunum, ileum and large intestine), the color of stool will not be black. What's the reason for that? Let me talk about it.

What's the reason for laxity and blackness

First: when bleeding occurs in the esophagus, stomach, duodenum, upper jejunum, pancreas and biliary tract, it will pull black stool like asphalt. This kind of stool is very black and shiny, just like asphalt. Discharging such stool is a manifestation of upper digestive tract bleeding. At this time, the patient should go to the hospital in time for examination to see which part of the bleeding, timely treatment.

Second: when the current gastrointestinal bleeding, the amount of bleeding is small, the stimulation to the intestinal tract is small, and when the intestinal peristalsis is slow, the black stool will be discharged. In addition, the bleeding of respiratory tract may also cause black stool. Of course, it doesn't mean that if there is black stool, there must be bleeding somewhere. This needs to be carefully distinguished, because when eating animal blood, the stool will also be black, which needs to be distinguished.

Third: people with gastrointestinal bleeding can adjust their diet, eat more fresh vegetables and fruits, and eat more foods containing vitamin C and vitamin K. When the amount of bleeding is large, stop eating and take the way of nutrient solution to supplement nutrition. When the amount of bleeding is small, you can eat some liquid food. No matter how the bleeding, spicy food can not eat, but also to quit smoking and alcohol.

matters needing attention

Black stool is likely to be gastrointestinal bleeding, but don't be too nervous. Pay attention to distinguish some false black stool caused by eating food. Of course, we should also be vigilant. After excluding black stool not caused by food, we should go to the hospital for examination in time.
