Blood in the stool


Hello, Dr.
Ke.
On April 27th, I noticed a significant amount of bright red blood when I went to the bathroom.
There was a large amount on the toilet paper and a long streak of blood in the toilet, similar to a menstrual period, but without any pain.
Previously, I occasionally noticed a small amount of blood on the toilet paper after bowel movements or a little blood mixed with stool, but I have never experienced such a large amount before.
Could you please advise on the possible causes and your recommendations? (I have regular daily bowel movements, a normal diet, and rarely experience constipation.)

Hello: In response to your question, painless large amounts of blood in the stool are typically characteristic of bleeding from internal hemorrhoids.
Common causes, aside from constipation, include prolonged straining during bowel movements or insufficient sleep.
If there is no ongoing bleeding, it is advisable to maintain good lifestyle habits and continue monitoring the situation.
However, if the bleeding occurs frequently, it is necessary to consult a physician for evaluation.

More Info


Rectal bleeding can be a concerning symptom, and it is essential to understand the potential causes and appropriate recommendations for management. Based on your description, you experienced a significant amount of bright red blood during a bowel movement, which is more than what you have previously encountered. While this can be alarming, it is crucial to consider various factors that could contribute to rectal bleeding.


Possible Causes of Rectal Bleeding
1. Hemorrhoids: One of the most common causes of rectal bleeding is hemorrhoids, which are swollen blood vessels in the rectal area. They can cause bright red blood on toilet paper or in the toilet bowl, especially after a bowel movement. Hemorrhoids can be internal or external, and while they can be uncomfortable, they are usually not serious.

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 during bowel movements and may cause bleeding, typically bright red.

3. Diverticular Disease: Diverticulosis involves the formation of small pouches in the colon wall, which can sometimes become inflamed or infected (diverticulitis). This condition can lead to rectal bleeding, often accompanied by abdominal pain.

4. Polyps or Colorectal Cancer: Although less common, polyps (growths on the colon lining) and colorectal cancer can cause rectal bleeding. This bleeding may be accompanied by changes in bowel habits, weight loss, or abdominal discomfort.

5. Gastrointestinal Infections: Infections in the gastrointestinal tract can lead to inflammation and bleeding. Symptoms may include diarrhea, abdominal pain, and fever.

6. Inflammatory Bowel Disease (IBD): Conditions such as Crohn's disease or ulcerative colitis can cause inflammation of the gastrointestinal tract, leading to rectal bleeding, diarrhea, and abdominal pain.


Recommendations
Given the significant amount of blood you observed, it is crucial to seek medical attention promptly. Here are some steps you should consider:
1. Consult a Healthcare Provider: Schedule an appointment with a gastroenterologist or your primary care physician. They may recommend a thorough evaluation, including a physical examination, a digital rectal exam, and possibly a colonoscopy to visualize the colon and identify any abnormalities.

2. Keep a Symptom Diary: Document any additional symptoms you experience, such as changes in bowel habits, abdominal pain, weight loss, or any other relevant details. This information can help your healthcare provider make a more accurate diagnosis.

3. Avoid Straining: If hemorrhoids or anal fissures are suspected, try to avoid straining during bowel movements. Increasing fiber intake through fruits, vegetables, and whole grains can help soften stools and promote regularity.

4. Stay Hydrated: Drinking plenty of fluids can also help prevent constipation and reduce the risk of straining during bowel movements.

5. Follow-Up: If you experience any worsening symptoms, such as increased bleeding, severe pain, or changes in bowel habits, seek immediate medical attention.


Conclusion
While rectal bleeding can be caused by various conditions, many of them are treatable. It is essential to take this symptom seriously and consult with a healthcare professional for a proper diagnosis and management plan. Early intervention can lead to better outcomes, especially if a more serious condition is identified. Remember, your health is paramount, and addressing these symptoms promptly is the best course of action.
