Published: Last Updated on

The appearance of Blood in the stool is usually an indicator of a problem in the digestive system. This Blood can come from any part of it, from the mouth, pharynx, esophagus, and the stomach, intestines, or anus. For this reason, the causes that cause the presence of Blood in the stool can be very numerous and varied.

Sometimes this problem is visible in the stool, but in others, the amounts of Blood are so small that they can be missed, so they would only be detectable in a medical examination. The color that the Blood gives to the stool will be decisive in determining which part of the digestive tract it comes from. In FastlyHealwe, tell you what the causes of the appearance of Blood in the stool are.

Bleeding in the upper part of the digestive tract

Black stools usually indicate that the problem is in the upper gastrointestinal tract and that the bleeding is coming. This part mainly encompasses the esophagus, stomach, and the first half of the small intestine. This implies that the Blood has had to pass through the digestive juices of the body as it flowed down through the intestines, which gives it this dark hue, similar to that of tar; Doctors often call this type of stool “manes.”

The causes that cause bleeding in this area are the following:

  • Gastric ulcer or duodenal ulcer: lesions on the stomach’s mucosa or the duodenum wall.
  • Esophageal varices: swollen and bleeding veins in the inner wall of the esophagus.
  • Tear in the esophagus from intense vomiting.
  • Gastritis: inflammation of the stomach lining.
  • Abnormal blood vessels
  • Esophageal hernias: parts of the stomach move into the chest.
  • Trauma or the presence of a foreign body.

Bleeding in the lower part of the digestive tract

On the other hand, when the stool is reddish-brown or directly bright and bright red, it is concluded that the Blood comes from the lower gastrointestinal tract, which contains the second half of the small intestine, the large intestine, the rectum, and year. The term hematochezia is used to describe this condition, and the causes that can cause it are the following:

  • Hemorrhoids – swollen veins in the anus or lower rectum (causing bright red Blood to appear).
  • Anal fissures.
  • Inflammatory bowel disease, such as Crohn’s disease or ulcerative colitis.
  • Diverticulosis: abnormal bags in the colon.
  • Intestinal polyps: bumps on the intestinal mucosa.
  • Colon or small intestine cancer.
  • Intestinal infection, for example, by parasites.
  • Vasculitis: inflammation of the blood vessels.
  • Angiodysplasia: vascular malformation of the colon.
  • Trauma

When to see the doctor?

If you observe Blood in the stool, you must consult your doctor to obtain an accurate diagnosis so that more severe pathologies such as cancer can be ruled out. In addition, long-term blood loss could lead to anemia, so treatment is essential.

In the case of Blood in the stool in children, they do not usually refer to severe pathology; it is generally related to constipation. Once in the office, the doctor will ask you questions about whether you take any medications and the symptoms that you present, and they will be performed from blood tests, stool culture to determine microorganisms in the stool, to a colonoscopy.
