What are the causes of Red Blood Stool

Published at : 08-07-2019 View : 16532

        Seeing blood in the toilet, on the outside of your stool, or with wiping after a bowel movement is common. Fortunately, most of the causes of such rectal bleeding are not life-threatening; common causes include hemorrhoids and anal fissures; however, the only way to be certain of the cause is to be evaluated by a healthcare provider.

About Red Blood in the Stool

        Red blood covering the surface of the stool means the bleeding is at or just above the anus. It is a common symptom and usually turns out to be a tear of the anus itself (anal fissure), especially if the stools are very hard and painful to pass. Less commonly such bleeding can be due to a proctitis (inflammation of the lower rectum usually due to IBD) or a rectal tumor. Inspection of the anus and sigmoidoscopy can identify these. In those who have a family history of colon cancer, or who are older than 50 years of age, the doctor may order a colon examination to exclude it usually a colonoscopy. Red blood mixed with the stools indicates the bleeding is acute and likely in the colon. Sometimes bleeding from the stomach can be so perfuse that it appears as bright red blood from the rectum. In this case, the individual may be faint and show signs of blood-loss shock  an emergency situation. Slower bleeding from the upper GI tract (esophagus, stomach, or duodenum) will show as darker blood or even as black, tar-like stools. Bleeding ulcers (often due to NSAIDS), or ruptured esophageal veins seen in liver disease are common causes.

 

 

What are the Causes of Red Blood in the Stool?

        Bloody stool is a sign that there is bleeding somewhere along the digestive tract. The blood can range in color from bright red to maroon, and it can even appear tarry and black if the bleeding is occurring higher up in the digestive tract.

Some of the more common, less-serious causes of bloody stool include:

  • Hemorrhoids – Hemorrhoids are swollen blood vessels found in the rectum or anus that can be itchy, painful and sometimes bleed. Those who suffer from hemorrhoids may notice bright red blood either in the toilet or coating the stool after a bowel movement.

  • Anal Fissures – An anal fissure is a small tear in the lining of the anus, which can cause bleeding and the sensation of ripping, tearing or burning after a bowel movement.

  • Peptic Ulcers – A peptic ulcer is an open sore in the lining of the stomach, upper end of the small intestine or duodenum caused by a bacterial infection.

  • Food poisoning – In addition to other issues, several foodborne organisms can cause bloody stool. A stool sample can help identify which bacteria you have been exposed to and how to treat the infection.

Other more serious causes of blood in stool include:

  • Crohn’s disease – Crohn’s disease causes inflammation of the digestive tract lining and can lead to severe diarrhea and abdominal pain.

  • Colon Polyps – Colon polyps are benign growths, or clumps of cells, that form along the lining of the colon. Although usually harmless, colon polyps can grow, bleed and become cancerous.

  • Cancer – Blood in stool can be a symptom of cancer along the digestive tract, colon cancer and anal cancer are two types that can cause bleeding; sometimes not noticeable to the naked eye to more severe bleeding.

Treatment for Red Blood in the Stool

        Most patients only pass from a few drops to a spoonful of blood in their stool, which is referred to as mild rectal bleeding. Usually, mild rectal bleeding can be evaluated and treated in the doctor’s office and does not require urgent treatment or hospitalization.In other cases, patients report repeatedly passing larger quantities of blood that may be accompanied by blood clots. This moderate to severe rectal bleeding can deplete blood supply, causing weakness, low blood pressure, dizziness or fainting. Moderate to severe rectal bleeding often requires evaluation and treatment in the hospital.
