Blood streaks in stool?


Hello, Dr.
Hsu.
Last Monday, I had diarrhea, and the next day I experienced diarrhea again after eating.
I switched to eating porridge, and after two to three days, I started passing soft stools.
Until a few days ago, my bowel movements were normal, but in the last two days, I have experienced some constipation, passing small, hard stools.
There are dark red streaks of blood near the stool that are visible to the naked eye, but there is no blood when I wipe with toilet paper.
However, I am experiencing pain in the anal area.
Could you please provide some guidance? Thank you!

Blood in the stool or changes in bowel habits, including alterations in stool shape or consistency, are abnormal gastrointestinal function changes.
These symptoms could indicate a range of conditions, from common hemorrhoids to more serious gastrointestinal diseases.
Based on your description of pain at the anal area accompanied by blood streaks, the likelihood of hemorrhoidal bleeding is highest.
It is recommended that you visit a gastroenterology department for further evaluation.

More Info


Blood-streaked stool can be alarming, and understanding its potential causes is crucial for determining the appropriate course of action. In your case, the presence of dark red blood in your stool, along with symptoms of diarrhea, constipation, and anal pain, warrants careful consideration.


Possible Causes of Blood-Streaked Stool
1. Hemorrhoids: One of the most common causes of blood-streaked stool is hemorrhoids, which are swollen veins in the lower rectum or anus. They can cause pain and bleeding, especially during bowel movements. Given that you mentioned anal pain, this could be a likely cause.

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, which might explain your symptoms.

3. Gastrointestinal Infections: Since you experienced diarrhea initially, it’s possible that a gastrointestinal infection could have caused irritation or inflammation in your intestines, leading to bleeding.

4. Diverticular Disease: Diverticulosis, which involves the formation of small pouches in the colon, can sometimes lead to bleeding. This is more common in older adults but can occur in younger individuals as well.

5. Inflammatory Bowel Disease (IBD): Conditions like Crohn's disease or ulcerative colitis can cause inflammation in the gastrointestinal tract, leading to symptoms such as diarrhea, abdominal pain, and blood in the stool.

6. Polyps or Colorectal Cancer: Although less common, especially in younger individuals, polyps or colorectal cancer can also present with blood in the stool. This is more concerning and typically requires further investigation.


When to Seek Medical Help
You should seek medical attention if you experience any of the following:
- Persistent or worsening symptoms
- Significant amounts of blood in your stool
- Severe abdominal pain or cramping
- Changes in bowel habits that last more than a few days
- Symptoms of anemia, such as fatigue, weakness, or shortness of breath

Recommended Actions
1. Consult a Healthcare Provider: Given your symptoms, it is advisable to consult a healthcare provider for a thorough evaluation. They may recommend a physical examination, and possibly a colonoscopy or other imaging studies, to determine the exact cause of the bleeding.

2. Dietary Adjustments: While waiting for your appointment, consider maintaining a diet high in fiber to help prevent constipation, which can exacerbate hemorrhoids or fissures. Drinking plenty of fluids is also essential.

3. Symptom Management: Over-the-counter medications may help alleviate pain or discomfort, but it’s best to consult with a healthcare provider before taking any new medications.

4. Monitor Symptoms: Keep track of your symptoms, including the frequency and appearance of your stools, any pain, and any other changes in your health. This information can be valuable for your healthcare provider.


Conclusion
Blood-streaked stool can arise from various causes, ranging from benign conditions like hemorrhoids to more serious issues. Given your symptoms, it is essential to consult a healthcare provider for a proper diagnosis and treatment plan. Early intervention can help prevent complications and ensure appropriate management of your condition.
