Common Causes and Risk Factors

  • Inflammatory bowel disease (ulcerative colitis or Crohn's disease)
  • Colon polyps or colorectal cancer
  • Straining during bowel movements or passing hard stools
  • Age over 50 and a family history of colon cancer

Signs and Symptoms

  • Bright red blood on toilet paper, in the toilet bowl, or coating the stool
  • Maroon or dark, tarry stools (melena)

How Dr. Scott Diagnoses Rectal Bleeding?

Dr. Scott uses a step-by-step approach:

Medical History and Symptom Review

He inquires about the time of onset, frequency and look of the bleeding, whether this is accompanied by some form of pain or itch, bowel movements, diet and medication selected, and whether anyone in the family has developed colorectal disease.

Physical Examination

A digital rectal exam is used to assess anything on the masses, tenderness, internal hemorrhoid, or fissure of the anus.

Endoscopic Evaluation

  • Anoscopy or proctoscopy to directly visualize the anal canal and distal rectum for hemorrhoids, fissures, or lesions.
  • Colonoscopy to inspect the entire colon, identify polyps, inflammation (IBD), diverticula, or malignancy, and allow for biopsy or polyp removal.

Laboratory and Stool Studies

Complete blood count to rule out anemia, inflammatory markers in case of IBD suspicion, as well as stool tests to detect occult blood or infection.

Advanced Imaging (if indicated)

CT scan or MRI could be requested to assess complicated diverticular illness, deep abscesses or indeterminate results in endoscopy.
