Blood in the stool?


Hello, doctor.
For the past three days, I have been experiencing blood in my stool.
The blood is separate from the stool, and it drips into the toilet when I have a bowel movement.
What could be the issue? Do I need further examination?

Dr. Chen Jiaming reply Surgery


Based on your description, it is possible that hard stools are causing internal hemorrhoids or mucosal friction bleeding, and it may also lead to anal fissures.
It is recommended to visit a colorectal surgery clinic for further evaluation.
Additionally, increasing fluid intake (young adults can increase by 1000-1500 milliliters daily) is advised to help soften the stools.

More Info


Blood in the stool can be a concerning symptom, and it is essential to understand its potential causes and when to seek medical help. The fact that you are experiencing blood in your stool, especially if it is separate from the stool itself, warrants prompt attention.


Possible Causes of Blood in Stool
1. Hemorrhoids: One of the most common causes of blood in the stool is hemorrhoids, which are swollen veins in the lower rectum or anus. They can cause bright red blood during bowel movements, often seen on the toilet paper or in the toilet bowl.

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 bleeding during bowel movements.

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

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: Polyps are growths on the lining of the colon or rectum that can bleed. Some polyps can develop into cancer over time, making it crucial to investigate any unexplained bleeding.

6. Inflammatory Bowel Disease (IBD): Conditions like Crohn's disease and ulcerative colitis can cause inflammation and ulceration in the gastrointestinal tract, leading to blood in the stool.

7. Other Causes: Other potential causes include gastrointestinal bleeding from ulcers, varices, or even certain medications that can irritate the gastrointestinal lining.


When to Seek Help
Given that you have been experiencing this symptom for three consecutive days, it is advisable to seek medical attention. Here are some specific signs that indicate you should see a doctor immediately:
- Persistent or Heavy Bleeding: If the bleeding is significant or does not stop, it is crucial to seek emergency care.

- Accompanying Symptoms: If you experience severe abdominal pain, dizziness, fainting, or any other concerning symptoms, you should seek medical attention right away.

- Changes in Bowel Habits: If you notice changes in your bowel habits, such as diarrhea or constipation, along with the bleeding, it is essential to consult a healthcare provider.


Recommended Actions
1. Consult a Healthcare Provider: Schedule an appointment with a gastroenterologist or your primary care physician. They may recommend tests such as a colonoscopy, which allows for direct visualization of the colon and rectum, and can help identify the source of the bleeding.

2. Keep a Record: Document any additional symptoms you experience, such as pain, changes in bowel habits, or dietary changes. This information can be helpful for your healthcare provider.

3. Avoid Self-Diagnosis: While it can be tempting to search online for answers, it is essential to rely on professional medical advice for an accurate diagnosis and treatment plan.

In conclusion, while there are several potential causes for blood in the stool, it is crucial to take this symptom seriously. Seeking medical attention promptly can help identify the underlying cause and ensure appropriate treatment. Remember, early intervention can lead to better outcomes, especially in cases where more serious conditions may be involved.
