There is a small amount of blood when wiping after a bowel movement?


Hello Dr.
Chen: Today, after having a bowel movement, I noticed a small amount of blood on the toilet paper.
However, I observed the following: 1.
There were no visible streaks of blood in the toilet or on the stool.
2.
I did not see any blood on the toilet paper after the first and second wipes; I only noticed it after the third and fourth wipes.
3.
The blood is bright red and the amount is very small.
Based on this information, is it more likely that the bleeding is due to excessive wiping causing an anal fissure? What should I observe during future bowel movements, or should I seek medical attention? Thank you!

Hello, sir.
It is indeed possible that the localized bleeding from the anus is the cause.
You may continue to observe the situation.
Alternatively, you can check for occult blood in the stool when there is no obvious bleeding, or undergo a direct rectal examination.
Changhua Hospital cares about your health.

More Info


Minor rectal bleeding can be a concerning symptom, but it is often benign and can be attributed to several common causes. Based on your description, it seems likely that the bleeding you observed could be due to a minor issue such as a hemorrhoid or an anal fissure, especially given the context of wiping and the characteristics of the blood.

1. Possible Causes:
- Anal Fissure: This is a small tear in the lining of the anus, often caused by passing hard stools or straining during bowel movements. The blood is typically bright red and may be seen on toilet paper after wiping.

- Hemorrhoids: Swollen blood vessels in the rectal area can also cause bright red blood on the toilet paper or in the toilet bowl. They can be internal or external and may cause discomfort or itching.

- Other Causes: While less common, other causes of rectal bleeding can include diverticular disease, colorectal polyps, or even more serious conditions like colorectal cancer. However, these are less likely given your symptoms and the absence of other concerning signs.

2. When to Seek Help:
- Immediate Attention: If you experience significant bleeding (more than a few drops), if the blood is dark or mixed with stool, or if you have accompanying symptoms such as severe pain, fever, or changes in bowel habits, you should seek medical attention promptly.

- Follow-Up: If the bleeding persists over several days, or if you notice changes in your bowel habits, such as diarrhea or constipation, it would be wise to consult a healthcare provider. They may recommend a physical examination, and possibly a colonoscopy or other imaging studies to rule out more serious conditions.

3. Self-Care and Observation:
- Dietary Adjustments: To prevent further issues, consider increasing your fiber intake through fruits, vegetables, and whole grains. Staying hydrated is also crucial, as it helps soften stools and reduces straining during bowel movements.

- Gentle Wiping: Be gentle when wiping to avoid further irritation. You might consider using moist wipes or a bidet if available.

- Monitor Symptoms: Keep an eye on your symptoms. If you notice any changes, such as increased frequency of bleeding, changes in stool color, or new symptoms, make sure to consult a healthcare provider.

4. Conclusion:
Based on your description, the likelihood of a minor issue such as an anal fissure or hemorrhoid is high, especially given the small amount of bright red blood and the circumstances surrounding its appearance. However, it is essential to monitor your symptoms and seek medical advice if the situation does not improve or worsens. Regular check-ups and being attentive to your body can help ensure that any potential issues are addressed early on.
