Rectal Bleeding: Causes and Concerns for Patients - Surgery

Blood in the stool


Hello Dr.
Chen, about six months ago, I started experiencing a dull pain in the upper part of my right thigh every time I felt the urge to have a bowel movement.
Two days ago, I had a prolonged and forceful bowel movement, and afterward, I noticed a pool of bright red blood on the toilet paper after wiping (it stopped after two or three wipes).
This morning, I had a bowel movement without any issues, but in the afternoon, I noticed bleeding again while wiping, although there was no pain.
What could be the cause of this? Thank you.
A few years ago, I had treatment for internal hemorrhoids, and I have an external hemorrhoid that has been present for over 20 years.
I haven't addressed it because it doesn't cause any pain.

Based solely on the symptoms you described, it is highly likely that you have hemorrhoids caused by hard stools leading to mucosal injury and bleeding.
It is recommended that you visit a colorectal surgery clinic for further examination and treatment.

More Info


Rectal bleeding can be a concerning symptom for many patients, and understanding its potential causes is crucial for appropriate management. Based on your description, it seems that you have experienced fresh blood on toilet paper after bowel movements, which can be alarming. Given your history of internal and external hemorrhoids, it is possible that these could be contributing to your current symptoms.


Possible Causes of Rectal Bleeding
1. Hemorrhoids: Since you have a history of internal hemorrhoids and an external hemorrhoid that has been present for many years, these are the most likely culprits for your rectal bleeding. Hemorrhoids can become engorged with blood, especially during bowel movements, leading to bleeding, particularly if you are straining or experiencing constipation.

2. Anal Fissures: Another common cause of rectal bleeding is an anal fissure, which is a small tear in the lining of the anus. This can occur due to passing hard stools or straining during bowel movements. Fissures can cause sharp pain during and after bowel movements, but they may not always be present, especially if the tear is small.

3. Diverticular Disease: Although less common, diverticulosis can lead to rectal bleeding. This condition involves the formation of small pouches in the colon wall, which can become inflamed or bleed.

4. Colorectal Polyps or Cancer: While less likely given your symptoms, it is important to consider that rectal bleeding can also be a sign of more serious conditions such as polyps or colorectal cancer, especially if there are changes in bowel habits, weight loss, or other systemic symptoms.

5. Other Conditions: Conditions such as inflammatory bowel disease (IBD), infections, or vascular malformations can also lead to rectal bleeding.


Recommendations for Management
1. Consult a Healthcare Provider: Given your symptoms and history, it is essential to consult a healthcare provider, preferably a gastroenterologist or a colorectal surgeon. They can perform a thorough evaluation, which may include a physical examination, anoscopy, or colonoscopy, to determine the exact cause of your bleeding.

2. Dietary Modifications: Increasing your fiber intake can help soften stools and reduce straining during bowel movements. Foods rich in fiber include fruits, vegetables, whole grains, and legumes. Staying well-hydrated is also important.

3. Avoid Straining: If you are experiencing constipation, consider using stool softeners or mild laxatives as recommended by your healthcare provider. Avoiding straining during bowel movements can help prevent exacerbation of hemorrhoids or fissures.

4. Topical Treatments: Over-the-counter topical treatments for hemorrhoids can provide relief from symptoms. These may include creams or ointments that contain hydrocortisone or witch hazel.

5. Surgical Options: If hemorrhoids are found to be the cause of your bleeding and conservative measures do not provide relief, surgical options may be considered. This could include procedures such as rubber band ligation or hemorrhoidectomy.


Conclusion
While the presence of fresh blood on toilet paper can be alarming, it is often associated with benign conditions such as hemorrhoids or anal fissures. However, it is crucial to seek medical evaluation to rule out more serious conditions. Early diagnosis and appropriate management can lead to better outcomes and improved quality of life. Please do not hesitate to reach out to a healthcare professional for further evaluation and personalized treatment options.
