Blood in stool is something which must not be taken casually and should be checked as soon as it is observed. If there is blood in stool, then it is an indication of blood loss somewhere in the digestive tract. There are various methods to detect the blood loss in stool and one of them is a stool test also known as occult test.

The stool in the test is checked by giving in the laboratory and confirmed by the reports. Sometimes this can also be confirmed by the tissue paper used right soon after a bowel movement. If it appears bright red in color then it’s a confirmation of blood loss in stools. It is quite possible that people having bloody stools might be unaware of the situation or have no other symptoms.

The following are some of the most common causes for blood in stool that you must look out for:

Fissures in Anus

Sometimes there can be a small tear or a cut in the tissue of the anus lining. It looks like chapped lips and can be a cause for blood loss in stools. Fissures are caused when large, hard stools are passed out from the digestive tract. One should keep a check for this.

Stomach Ulcers

Sometimes, there is an open sore in the small intestine at the upper end also known as the duodenum. This open sore bleeds and causes the blood in stool. Ulcers can be caused by heavy doses of drugs which are anti-inflammatory like aspirin, naproxen and ibuprofen. One should be aware of the side effects caused by such drugs while taking them.

Cancer / Polyps

Colorectal cancer can cause bleeding in the digestive tract but it is not noticeable with a naked eye and a laboratory test is recommended for this. Small growths called polyps can also cause cancer and in turn cause internal bleeding.

Problems of the Esophagus

If there are varicose veins in the esophagus or there are tars in the esophagus, then it’s a matter of concern as this can also cause blood loss in the digestive tract and hence bloody stools


Angiodysplasia is a disease where some abnormal and fragile nerves or blood vessels lead to bleeding stools.


Gastroenteritis is a bacterial infection in bowel areas and stomach. Our immune system is designed in such a manner, that it tries to fight it on its own. This problem can lead to traces of mucous and blood and can also cause vomiting and cramps in the stomach.

Whatever the cause of blood in the stool is, it must be checked and consultation must be taken. While in some cases, the problem may not be that severe but in others, it may need a proper treatment. A thorough examination by a qualified physician followed by proper medication is advisable. The problem of blood in stools should not be taken lightly and should not be avoided under any circumstances.
