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

Blood in the stool can be alarming, and it is essential to understand the potential causes and when to seek medical attention. The presence of bright red blood on toilet paper or in the toilet bowl can indicate several conditions, ranging from benign to serious.

Possible Causes of Blood in Stool
1. Hemorrhoids: One of the most common causes of bright red blood in the stool is hemorrhoids. These are swollen veins in the lower rectum or anus that can bleed during bowel movements, especially if straining occurs.

2. Anal Fissures: Small tears in the lining of the anus, often caused by passing hard stools, can lead to bleeding and a burning sensation during bowel movements.

3. Diverticular Disease: Diverticulosis, which involves the formation of small pouches in the colon wall, can sometimes lead to diverticulitis, where these pouches become inflamed or infected, resulting in bleeding.

4. Gastrointestinal Infections: Certain infections can cause inflammation and bleeding in the gastrointestinal tract, leading to blood in the stool.

5. Polyps or Colorectal Cancer: While less common, polyps (growths on the colon lining) and colorectal cancer can also present with blood in the stool. These conditions are more likely in individuals over 50 or those with a family history of colorectal cancer.

6. Inflammatory Bowel Disease (IBD): Conditions such as Crohn's disease or ulcerative colitis can cause significant inflammation and bleeding in the digestive tract.


When to Seek Medical Help
It is crucial to seek medical attention if you notice blood in your stool, especially if:
- The bleeding is persistent or recurrent.

- You experience significant abdominal pain or discomfort.

- You have other symptoms such as fever, weight loss, or changes in bowel habits.

- You feel faint or lightheaded, which could indicate significant blood loss.


Understanding Your Symptoms
In your case, the bright red blood observed on toilet paper and in the toilet bowl, along with the burning sensation, could suggest hemorrhoids or anal fissures, particularly if you have been straining during bowel movements. The fact that your stool appeared brown without visible blood during a later bowel movement is a positive sign, as it may indicate that the bleeding was not continuous.

However, it is essential to monitor your symptoms closely. If the bleeding continues, worsens, or if you develop new symptoms, it is advisable to consult a healthcare professional. They may perform a physical examination, and possibly recommend further tests such as a colonoscopy to determine the underlying cause of the bleeding.


Conclusion
While blood in the stool can often be attributed to benign causes like hemorrhoids or anal fissures, it is essential to take it seriously. Understanding the potential causes and knowing when to seek help can lead to timely diagnosis and treatment. If you have concerns about your symptoms or if they persist, do not hesitate to reach out to a healthcare provider for a thorough evaluation.
