Blood in Stool: Causes and When to Seek Help - Gastroenterology and Hepatology

More Info

---

Seeing bright red blood in your stool can be alarming, and it's important to understand the potential causes and when to seek medical attention. Blood in the stool can originate from various parts of the gastrointestinal (GI) tract, and the color of the blood can provide clues about its source. Bright red blood typically indicates that the bleeding is occurring in the lower part of the GI tract, such as the rectum or colon, while darker blood may suggest bleeding from higher up in the digestive system.

Common causes of bright red blood in the stool include:
1. Hemorrhoids: Swollen blood vessels in the rectum or anus can rupture during bowel movements, leading to bright red blood. This is one of the most common causes and is often accompanied by itching or discomfort.

2. Anal Fissures: Small tears in the lining of the anus can occur due to passing hard stools, resulting in pain and bleeding.

3. Diverticular Disease: Diverticula are small pouches that can form in the colon. If they become inflamed or infected (diverticulitis), they can bleed.

4. Colorectal Polyps: These are growths on the lining of the colon or rectum that can bleed. While many polyps are benign, some can develop into cancer over time.

5. Colorectal Cancer: Blood in the stool can be a sign of colorectal cancer, especially if it is accompanied by other symptoms such as changes in bowel habits, weight loss, or abdominal pain.

6. Gastrointestinal Infections: Certain infections can cause inflammation and bleeding in the intestines.

Given that you mentioned experiencing this issue multiple times over the past few months, it is crucial to consult a healthcare professional. While occasional blood in the stool may be due to benign causes like hemorrhoids or fissures, recurrent bleeding warrants further investigation to rule out more serious conditions.


When to Seek Help
You should seek medical attention if you experience any of the following:
- Persistent or recurrent bleeding: If the blood in your stool continues or recurs frequently, it is essential to see a doctor.

- Accompanying symptoms: If you have additional symptoms such as severe abdominal pain, changes in bowel habits, unexplained weight loss, or fatigue, these could indicate a more serious condition.

- Large amounts of blood: If you notice a significant amount of blood or if it is accompanied by dizziness or fainting, seek emergency care immediately.


What to Expect at the Doctor's Office
When you visit a healthcare provider, they will likely perform a thorough history and physical examination. They may ask about your symptoms, dietary habits, and any medications you are taking. Depending on your situation, they may recommend tests such as:
- Blood tests: To check for anemia or signs of infection.

- Stool tests: To identify any pathogens or blood.

- Colonoscopy: A procedure that allows the doctor to examine the inside of your colon and rectum for abnormalities.


Conclusion
In summary, while bright red blood in your stool can be caused by relatively benign conditions, it is essential to take it seriously, especially if it recurs. Consulting with a healthcare professional will help determine the underlying cause and appropriate treatment. Early diagnosis and intervention can significantly improve outcomes, particularly if a serious condition is present. Don't hesitate to reach out to a doctor for a proper evaluation and peace of mind.
