What are the reasons for bloody stool? Do you need to do enteroscopy?

Zhang Shuhong, a physician at Changsha Dongda anorectal Hospital, said that hematochezia is more common in lower gastrointestinal bleeding. There are many reasons for fecal bleeding, not just hemorrhoids. However, in clinical practice, when many patients have stool bleeding, it is taken for granted that they have hemorrhoids, so as to delay the treatment. As a result, the early treatment opportunity is often delayed.

Zhang Shuhong reminded that hematochezia is very harmful to the human body. Long term hematochezia can also cause anemia and other complications. Therefore, whether it is hemorrhoids or hematochezia, we should go to a regular hospital in time for early treatment. The common causes of hematochezia in clinic are as follows.

1. Hemorrhoids and bloody stool

When hemorrhoids and bloody stool occur, the main symptoms are dripping blood or jet bleeding in the stool, which is bright red. It often occurs when the stool is dry, often accompanied by prolapse of hemorrhoids.

2. Anal fissure hematochezia

Anal fissure hematochezia is more common in patients with constipation or diarrhea. It is common to wipe blood on the paper after defecation, accompanied by anal pain.

3. Intestinal polyp hematochezia

Most of the blood in the stool of intestinal polyps is painless stool bleeding. It bleeds during defecation and stops after defecation. The amount varies. Generally, the blood is not mixed with feces, or the position and quantity of polyps are high, and can also be mixed with feces.

4, ulcerative colitis, intestinal infectious diseases, bloody stool.

Ulcerative colitis with bloody stool is mostly mucus stool or purulent stool, accompanied by left lower abdominal pain or lower abdominal pain. Intestinal infectious diseases also cause pus (sticky liquid) bloody stools, such as bacillary dysentery and amebic enteropathy.

5. Colorectal tumor hematochezia

Most of the blood in stool is bright red or dark red, with pus or mucus, or black stool. The sense of stool is frequent. Sometimes only a small amount of blood or mucus is discharged without feces. In the late stage, there may be symptoms such as abdominal pain, abdominal distention, constipation or diarrhea, weight loss and so on.

Zhang Shuhong reminded that enteroscopy is a very important method to check lower gastrointestinal diseases such as enteritis, intestinal polyps and colorectal tumors. In case of bloody stool, we should first improve the basic examinations such as digital anal examination and anoscope, and then see whether enteroscopy is needed in combination with the following conditions.
