Blood in Stool: Common Causes and When to Seek Help - Surgery

More Info

Seeing blood in your stool or on toilet paper after a bowel movement can be concerning and may indicate a variety of underlying issues. It's essential to understand the potential causes and when to seek medical attention.


Common Causes of Blood in Stool
1. Hemorrhoids: One of the most common causes of blood on toilet paper is hemorrhoids, which are swollen veins in the lower rectum or anus. They can cause bright red blood during bowel movements, especially if there is straining involved.

2. Anal Fissures: These are small tears in the lining of the anus, often caused by passing hard stools. They can lead to sharp pain and bright red blood during or after bowel movements.

3. Diverticular Disease: Diverticulosis, which involves the formation of small pouches in the colon wall, can lead to diverticulitis when these pouches become inflamed or infected. This condition can cause bleeding.

4. Gastrointestinal Infections: Infections caused by bacteria, viruses, or parasites can lead to inflammation and bleeding in the gastrointestinal tract.

5. Inflammatory Bowel Disease (IBD): Conditions such as Crohn's disease and ulcerative colitis can cause chronic inflammation of the digestive tract, leading to symptoms including blood in the stool.

6. Polyps or Colorectal Cancer: While less common, polyps (non-cancerous growths) or colorectal cancer can cause bleeding. This is particularly concerning if the bleeding is persistent or accompanied by other symptoms like weight loss or changes in bowel habits.

7. Gastrointestinal Bleeding: Conditions affecting the upper gastrointestinal tract, such as peptic ulcers or esophageal varices, can also lead to blood in the stool, although this blood may appear darker or tarry.


When to Seek Medical Help
It is crucial to consult a healthcare professional if you notice blood in your stool, especially if:
- The bleeding is persistent or recurrent.

- You experience significant pain, especially if it is severe.

- You notice changes in your bowel habits, such as diarrhea or constipation lasting more than a few days.

- You have accompanying symptoms like fever, weight loss, or fatigue.

- The blood is dark or tarry, which may indicate bleeding from higher up in the gastrointestinal tract.


Diagnostic Approach
When you visit a healthcare provider, they may perform a physical examination and ask about your symptoms, medical history, and lifestyle factors. They might recommend tests such as:
- Blood Tests: To check for anemia or signs of infection.

- Stool Tests: To identify infections or blood.

- Colonoscopy: A procedure that allows direct visualization of the colon and rectum, which can help identify the source of bleeding.

- Imaging Studies: Such as CT scans, if necessary, to evaluate the gastrointestinal tract.


Conclusion
While blood in the stool can often be attributed to benign conditions like hemorrhoids or anal fissures, it is essential to take it seriously, especially if it is a new symptom or if you have other concerning signs. Early diagnosis and treatment can help manage any underlying conditions effectively. Always consult with a healthcare professional for personalized advice and treatment options.
