Rectal bleeding


Hello Doctor: Yesterday, I experienced significant pain while having a bowel movement and noticed some blood, both on the toilet paper and in the toilet.
I had a warm sitz bath yesterday and used the suppository that the doctor prescribed earlier.
Today, there was no blood during my bowel movement.
Earlier this month, I had a colonoscopy due to previous instances of rectal bleeding, and the results were normal! Could this be an anal fissure or hemorrhoids? Since my condition has improved today, do I still need to see a doctor? If my colonoscopy results were normal, is there still a possibility of colon cancer? Thank you!

Based on your description, it seems more like the typical symptoms of an anal fissure, which include pain during bowel movements accompanied by slight bleeding.
The common causes are often constipation or diarrhea.
The fundamental treatment is to address the bowel movement issues, along with warm sitz baths.
Warm sitz baths can help alleviate pain, maintain cleanliness, and promote blood circulation.
You can also purchase hemorrhoid suppositories over the counter for use.
If the symptoms persist without improvement, it is advisable to consult a physician.
As for whether another colonoscopy is needed, it depends on when the last colonoscopy was performed.
If it has been more than three years, it may be worth considering another one.

More Info


When it comes to rectal bleeding, it can often be a source of concern and anxiety for many individuals. Based on your description, it seems that you experienced pain and bleeding during a bowel movement, which is a common symptom associated with conditions such as hemorrhoids or anal fissures. Given that you had a colonoscopy earlier this month that returned normal results, the likelihood of a more serious condition, such as colorectal cancer, is significantly reduced, especially if you are under the age of 50 and have no other risk factors.

Understanding Hemorrhoids and Anal Fissures:
1. Hemorrhoids: These are swollen veins in the lower rectum or anus that can cause discomfort, pain, and bleeding. The bleeding from hemorrhoids is typically bright red and may be seen on the toilet paper or in the toilet bowl. Hemorrhoids can be internal (inside the rectum) or external (under the skin around the anus). Symptoms may include itching, swelling, and pain, especially during bowel movements.

2. Anal Fissures: An anal fissure is a small tear in the lining of the anus, often caused by passing hard or large stools. This condition is usually associated with sharp pain during bowel movements and may also result in bright red bleeding. The pain can be severe and may lead to a fear of having a bowel movement, which can create a cycle of constipation and further fissuring.

Your Recent Experience:
The fact that you experienced bleeding and pain during a bowel movement, but did not have bleeding during your next bowel movement, suggests that it may have been a temporary issue, possibly related to a fissure or a mild case of hemorrhoids. The warm sitz baths you mentioned can help soothe the area and promote healing, and the use of topical treatments prescribed by your doctor can also be beneficial.

When to Seek Further Medical Attention:
- If you experience recurrent bleeding, increased pain, or if the bleeding returns, it would be wise to consult with your healthcare provider.

- If you notice any changes in your bowel habits, such as persistent diarrhea or constipation, or if you experience significant weight loss, these could be signs that warrant further investigation.

- Given that you have already had a colonoscopy, it is unlikely that you have colorectal cancer, especially with a normal result. However, if you have a family history of colorectal cancer or other risk factors, discussing this with your doctor is important.

Conclusion:
In summary, based on your symptoms and the normal colonoscopy results, it is likely that you are dealing with either hemorrhoids or an anal fissure. The improvement you noted after using a sitz bath and topical treatments is a positive sign. However, if symptoms persist or worsen, seeking further medical evaluation is advisable. Regular follow-ups with your healthcare provider can help ensure that any underlying issues are addressed promptly, and they can provide personalized advice based on your specific health needs.
