Discovering blood in stool can be alarming, but understanding its potential causes and when to seek medical attention is crucial. This guide provides a visual and informative overview of common reasons behind this symptom, helping you navigate concerns with confidence.
What Does Blood in Stool Look Like?
Blood in stool can appear in various ways, depending on the source of bleeding:
- Bright Red Blood: Often seen on the toilet paper or in the toilet bowl, this typically indicates bleeding in the lower digestive tract, such as the rectum or anus.
- Dark or Tarry Stool: Known as melena, this suggests bleeding higher up in the digestive tract, like the stomach or small intestine.
- Maroon or Mixed Blood: This may indicate bleeding in the colon or upper digestive tract.
📌 Note: Always consult a healthcare professional if you notice blood in your stool, as it can be a sign of underlying conditions.
Common Causes of Blood in Stool
1. Hemorrhoids
Hemorrhoids are swollen veins in the rectum or anus, often causing bright red blood during bowel movements. They are usually painless and linked to straining during bowel movements or pregnancy.
2. Anal Fissures
Small tears in the lining of the anus can cause sharp pain and bright red blood on toilet paper. These fissures are commonly due to constipation or hard stools.
3. Diverticulitis
Inflammation of small pouches in the colon (diverticula) can lead to rectal bleeding, abdominal pain, and fever. This condition is more common in older adults.
4. Colitis
Inflammation of the colon, such as in ulcerative colitis or Crohn’s disease, can cause bloody diarrhea, abdominal cramps, and urgency.
5. Polyps and Colon Cancer
Colorectal polyps or cancer may cause dark or bright red blood in the stool, often accompanied by changes in bowel habits or unexplained weight loss.
📌 Note: Early detection of polyps or cancer through screenings like colonoscopy can be life-saving.
When to See a Doctor
While some causes of blood in stool are minor, others require immediate medical attention. Seek help if you experience:
- Persistent or heavy bleeding
- Severe abdominal pain
- Dizziness or weakness
- Changes in bowel habits lasting more than a few days
Diagnostic Tests for Blood in Stool
To determine the cause, your doctor may recommend:
- Stool Tests: To check for blood or infections.
- Colonoscopy: To examine the colon for polyps, cancer, or inflammation.
- Endoscopy: To inspect the upper digestive tract for bleeding sources.
Preventive Measures
Reduce the risk of blood in stool by:
- Eating a high-fiber diet to prevent constipation.
