Dark red mucous blood in stool

Although bleeding in the stool is something that many people experience, there are many different types of bleeding in the stool. Because the causes of bleeding in the stool are different, some people find that the color and shape of their blood are different when bleeding in the stool occurs. Many people find that the blood in their stool is dark red and mucous. What causes this?

1. Causes

Blood in stool is generally divided into fresh blood in stool, tarry blood in stool and occult blood in stool. The common causes are described below.

1. Fresh blood in stool: generally comes from the lower end of the ileum, colon, rectum, and anus. The stool is bright red or dark red and may be mixed with mucus, pus and blood. Common diseases are: hemorrhoids and anal fissure bleeding. The blood in the stool caused by hemorrhoids may flow out in a jet-like manner during defecation or drip after defecation; the amount of blood in the stool caused by anal fissure is small, but the anal pain is more severe. Rectal polyps bleed, the amount of blood in the stool is not large, the blood is attached to the surface of the stool, and sometimes the stool becomes thinner and strip-shaped or has pressure marks. Dysentery causes bloody stools with pus and blood, frequent bowel movements, and pain in the left lower abdomen.

2 Tarry stools: that is, black stools. If upper gastrointestinal bleeding is not vomited out, the blood will stay in the intestines for a long time. The hemoglobin in the blood will combine with the sulfide in the intestines to form ferrous sulfide. Ferrous sulfide makes the stool black and shiny, like tar. The presence of tarry stools indicates that the amount of bleeding has reached more than 60 ml. But be aware that certain foods and medicines can cause stools to turn black, which can be identified using a fecal occult blood test.

3 Occult blood in stool: Any small amount of gastrointestinal bleeding that does not cause changes in stool color and only tests positive for occult blood in the stool is called occult blood in stool. All diseases that cause gastrointestinal bleeding can cause occult blood in the stool, the most common of which are gastric ulcers and gastric cancer.

(II) Rescue measures

The first aid measures are basically the same as those for vomiting blood. Lie quietly in bed, reduce activity, observe the amount of bleeding, use hemostatic drugs appropriately, and go to the hospital for emergency treatment in time if fainting or shock occurs.
