Causes of having Blood in the Stool

Published at : 21-08-2019 View : 6981

        If blood is coming from the rectum or the lower colon, red blood will mix with the stool, bleeding can come from one or more of these areas from a small area like an ulcer on the lining of the stomach.


  Rectal pain

  Bright red blood present in or on the stool

  Pain in the stomach, lower abdomen, rectum, or back

  Change in stool color to black, red, or maroon

  Stool test positive for occult blood loss (blood may present, but you cannot see it)


  Dizziness, lightheadedness

  Fainting, palpitations or rapid heartbeat




  Bloody stool and bloody diarrhea are both signs of colorectal cancer, and therefore they should never be ignored. The sooner you are diagnosed, the more effective treatment options will be. There are other causes of blood in your stool, such as:

  Hemorrhoids otherwise known as piles are swollen blood vessels in the rectum. They often cause itching or burning sensation, and they may bleed. The blood seen with hemorrhoids is usually bright red.

  Gastroenteritis is an infection in the stomach or intestines caused by a virus or bacteria, such as norovirus or food poisoning. It can lead to bloody diarrhea. Nausea and vomiting may also be present.

  Diverticula are tiny pockets or bulges in the lining of the lower bowel. They can get infected and cause pain, and if they rupture, they can cause bleeding. In some cases, there may be significant bleeding even without pain.

  Polyps in the bowel polyps are clumps of cells that can grow in the lining of the colon and rectum. Polyps don’t always cause problems, but they can develop into cancer if not removed. They may also bleed a little during bowel movements.

  Proctitis occurs when the tissues that make up the rectum become inflamed, often resulting in pain and bleeding.

  Colitis occurs when the tissues lining the colon become inflamed. A type of colitis called ulcerative colitis can also cause ulcers, or open, progressive sores, that are prone to bleeding.

  Angiodysplasia is rectal bleeding caused by abnormal blood vessels in the gastrointestinal tract. It usually happens in elderly people, and it doesn’t normally cause pain.

  Anal sex and STIs Damage to the anus from sexually transmitted infections (STIs) or anal sex can cause bleeding in the rectum. This blood is usually bright red.

  Anticoagulant medications also known as blood thinners can sometimes cause internal bleeding, which may be seen in the stool. That blood would normally cause black and tarry stools.


  If bleeding is associated with an already diagnosed medical condition, our doctor will discuss ways to manage, reduce, and track symptoms. If the cause of stool bleeding is unknown, our doctor will normally ask questions about symptoms and the person's medical history, depending on the severity, frequency, and accompanying symptoms, the doctor will work out if further testing is required. Common tests associated with stool bleeding include:

   Physical examination of the anus and rectum

   Analysis of a stool sample

   Colonoscopy or flexible sigmoidoscopy where the colon is examined by the insertion of a tube with a camera

   Anoscopy where a device is inserted into the anus to examine the tissue

   Biopsy or removal of a small tissue sample for examination

  Heng Kang clinic works together to provide a coordinated care approach to achieve the best outcome for every patient.
