Anal Pain and Minor Bleeding During Bowel Movements - Surgery

Experiencing significant pain in the anus during bowel movements, accompanied by slight bleeding?


Hello doctor, in January and February of this year, I experienced significant pain in my anus during bowel movements, and I noticed some bright red blood when wiping.
However, there was only a slight amount of fresh blood on the surface of the stool.
During my annual health check in April, the result for the fecal occult blood test was normal.
Recently, I have experienced similar symptoms again, and even after bowel movements, I still feel pain while sitting on a chair.
After a day or two, the bowel movements return to normal and are painless.
Could the pain during bowel movements and the slight presence of blood indicate colorectal cancer? Thank you for taking the time to read this.

Answer: A fecal occult blood test may yield false-negative results.
If a person is over 40 years old and experiences rectal bleeding, it is advisable to undergo a colonoscopy for further evaluation.

More Info


Anal pain and minor bleeding during bowel movements can be concerning symptoms, and it's understandable to seek clarity on their potential causes. Based on your description, it seems that you are experiencing intermittent anal pain accompanied by slight bleeding, particularly when passing stool. While these symptoms can be alarming, they are not necessarily indicative of colorectal cancer.

The most common causes of anal pain and minor bleeding during bowel movements include:
1. Anal Fissures: These are small tears in the lining of the anus, often caused by passing hard or large stools. Symptoms typically include sharp pain during and after bowel movements, and you may notice bright red blood on the toilet paper or on the stool itself. Anal fissures are quite common and can heal with proper care, including dietary adjustments to soften stools and the use of topical treatments.

2. Hemorrhoids: Swollen blood vessels in the rectal area can lead to pain, itching, and bleeding. Like fissures, hemorrhoids can cause bright red blood on the toilet paper or in the toilet bowl. They can be internal or external and may require lifestyle changes, topical treatments, or, in some cases, surgical intervention.

3. Infections or Inflammatory Conditions: Conditions such as anal abscesses or sexually transmitted infections can also cause pain and bleeding. These would typically present with additional symptoms, such as swelling, fever, or discharge.

4. Other Gastrointestinal Issues: Conditions such as diverticulitis or inflammatory bowel disease (IBD) can cause similar symptoms, but they are usually accompanied by other gastrointestinal symptoms like diarrhea, abdominal pain, or changes in bowel habits.

Given that your recent health check-up showed normal results for fecal occult blood, it is less likely that you are dealing with colorectal cancer. However, it is essential to monitor your symptoms closely. If the pain persists, worsens, or if you notice significant changes in your bowel habits, it would be prudent to consult a healthcare professional for further evaluation.


Recommendations for Management:
- Dietary Changes: Increasing fiber intake through fruits, vegetables, and whole grains can help soften stools and reduce the risk of fissures and hemorrhoids. Staying well-hydrated is also crucial.

- Regular Bowel Habits: Establish a routine for bowel movements to avoid straining. If you feel the urge to go, try not to delay.

- Topical Treatments: Over-the-counter creams or ointments designed for hemorrhoids or fissures can provide relief. Warm sitz baths can also soothe the area.

- Avoid Straining: When using the bathroom, try to relax and avoid straining, as this can exacerbate fissures and hemorrhoids.

- Follow-Up: If symptoms persist or worsen, or if you experience additional symptoms such as significant weight loss, changes in bowel habits, or severe abdominal pain, seek medical attention promptly.

In conclusion, while your symptoms may be concerning, they are more commonly associated with anal fissures or hemorrhoids rather than colorectal cancer, especially in light of your recent health check results. However, ongoing monitoring and appropriate lifestyle adjustments can significantly alleviate your discomfort. Always consult with a healthcare provider for personalized advice and treatment options.
