rectal bleeding

Rectal bleeding refers to the presence of blood in or on the stool, or blood from the rectum or anus. It is a common symptom that can be alarming, but in many cases, it’s due to a relatively benign condition. However, rectal bleeding can also signal a more serious underlying issue, such as hemorrhoids, anal fissures, or even colorectal cancer. The location and amount of bleeding, along with other accompanying symptoms, can help determine the cause.

Types of Rectal Bleeding:

  1. Bright Red Blood:

    • Common Causes: Bright red blood typically indicates that the source of bleeding is in the lower gastrointestinal tract, such as the rectum or anus. Common causes include:

      • Hemorrhoids: Swollen veins in the rectum or anus that can cause bleeding, often noticed during bowel movements.

      • Anal Fissures: Small tears in the skin around the anus, which can cause sharp pain and bleeding.

      • Proctitis: Inflammation of the rectum that can cause blood during or after bowel movements.

      • Colorectal Polyps: Non-cancerous growths in the colon or rectum that can bleed.

  2. Dark or Maroon Blood:

    • Common Causes: Dark or maroon-colored blood suggests that the bleeding is coming from higher in the gastrointestinal tract, such as the colon or small intestine. Conditions that can cause this type of bleeding include:

      • Diverticulosis: Small pouches that form in the wall of the colon and can bleed.

      • Colorectal Cancer: Cancer of the colon or rectum can cause significant bleeding, often with other symptoms like weight loss or changes in bowel habits.

      • Inflammatory Bowel Disease (IBD): Conditions like Crohn’s disease or ulcerative colitis can lead to ulceration and bleeding in the digestive tract.
