Seeing blood in your stool can be alarming. It can happen for many reasons, from minor to more serious ones. Additionally, the color of the blood may also vary. It might look bright red, dark red, or even black. This, as a result, shows where in the digestive system the bleeding is coming from.Sometimes, the cause is not serious, like hemorrhoids. However, in other cases, it may be due to ulcers or even cancer. That’s why it’s important to see a doctor if you notice blood in your stool.

What is Blood in Stool or Bloody Stool?

Blood in the stool, also called rectal or GI bleeding, means there is blood in your bowel movement. Depending on where the bleeding is coming from, the blood can look bright red or make your stool look dark and sticky, like tar.

As a result, this symptom can point to different issues. It could be something mild, like diarrhea or hemorrhoids. However, it can also be a sign of more serious problems like inflammatory bowel disease or colon cancer.

Types

  • Bright Red Blood: This means the bleeding is coming from the lower part of your digestive system, like the rectum or colon. Common causes include hemorrhoids, constipation, and anal fissures.
  • Black or Tarry Stool: This means the bleeding is from higher up in your digestive system, such as the stomach or upper GI tract. Additionally, it can also be a sign of conditions like ulcerative colitis that cause bleeding in that area.

How Common is Blood in Stool or Bloody Stool?

Blood in stool is also known as bloody stool, rectal bleeding, and GI bleeding. It is a common symptom of various gastrointestinal issues. However, occasional traces and minor rectal bleeding may indicate minor causes like constipation, and anal fissure.

Persistent or significant blood in the stool often signals serious GI conditions. Examples include hemorrhoids, inflammatory bowel disease (IBD), peptic ulcer disease, and colon cancer. In such cases, prompt medical evaluation, like a rectal examination, is required.

Common Symptoms of Blood in Stool

Common Causes of Blood in Stool

Gastroenterologists typically consider the following possible causes of blood in stool:

  • Hemorrhoids: Swollen blood vessel in the lower digestive tract, rectum, or anus that can rupture and bleed. This is especially true if you are passing bright red blood in your poop, a condition called hematochezia.
  • Anal Fissure: An anal fissure is a small tear in the lining of the anus. It is caused by passing hard stools, straining, pregnancy, and more. As a result, it can cause anal pain during and after bowel movement.
  • Gastrointestinal Ulcer: Open sores in the stomach or small intestine that can cause internal bleeding.
  • Diverticular Disease: It arises from the formation of diverticula in the large intestine lining, leading to rectal bleeding. While many individuals remain asymptomatic, some may experience diverticulitis due to infection in these pouches.
  • Colon Cancer: Blood in the stool can be an early sign of colon cancer, especially if accompanied by weight loss or changes in bowel habits. That’s why it’s crucial to inform your doctor of any signs right away. Since colon cancer can appear in different ways, the blood in the stool may vary in color, from bright red to dark and tarry. The color helps indicate the tumor’s location in the GI tract. For example, tumors near the rectum often cause dark red or maroon stools. Meanwhile, rectal tumors cause bright red stool.
  • Inflammatory Bowel Disease (IBD): Conditions like Crohn’s Disease and Ulcerative Colitis can cause bleeding from inflamed digestive tract tissues.
