Why Am I Passing a Lot of Blood While Having a Bowel Movement?

Hematochezia is a relatively common symptom, and there are many reasons that can lead to it. Firstly, the characteristics of hematochezia should be observed. If the blood is bright red and drips on the feces, it is generally related to hemorrhoids. If the blood shows purulent bloody stool, it should be noted that there are many possible causes, and it is necessary to go to the hospital for examination in time. Next, we will briefly understand what hematochezia is.

1. Hemorrhoids are the most common cause of hematochezia. The bleeding is related to defecation, and often occurs after defecation or in a dripping or spraying shape. The color is bright red, and sometimes accompanied by prolapse of hemorrhoids, discomfort, pain and other symptoms.

2. Dysentery is an acute intestinal infectious disease caused by dysentery bacilli. The symptoms include abdominal pain, diarrhea, tenesmus, purulent bloody stool, and may be accompanied by fever and other symptoms of systemic infection. The symptoms disappear rapidly after treatment. A few patients may have prolonged symptoms and develop chronic dysentery, with recurrent diarrhea, mucus stool, purulent bloody stool, stool bleeding and other symptoms similar to large intestine cancer.

3. High-level bleeding in the digestive tract, such as bleeding caused by rupture of varicose veins in the lower part of the esophagus and bleeding from peptic ulcer, etc. Because the blood stays in the intestinal cavity for a long time after leaving the blood vessels, the feces discharged are tarry, black or coffee-colored, and pasty. The stool occult blood test is positive.

4. Low-level bleeding in the digestive tract, especially bleeding from the lower colon and rectum, has bright red blood and is closely related to defecation. Among them, the characteristic of hemorrhoid bleeding is that blood is expelled from the anus during forced defecation, with variable amounts, or blood on toilet paper after defecation, or dripping blood, or spraying shape. The hematochezia caused by anal fissure is generally small in amount and accompanied by severe pain. Bleeding from rectal polyps is often seen in children when blood contaminates the area around the anus during defecation. If it occurs in adults, the feces contain blood mixed with mucus and purulent secretions, with a strange odor, and symptoms of thinning stool. Attention should be paid to the possibility of cancer in the rectum and lower colon.
