Rectal bleeding


In the past two days, I have experienced pain during bowel movements.
There were traces of blood on the toilet paper after wiping, but no blood on the stool itself.
The amount of blood was minimal, similar to a minor scrape.
The next day, the blood traces decreased, but there was still some pain.
Today, I had a bowel movement without pain, but I noticed a small amount of bright red blood at the end of the stool.
There were no blood traces on the toilet paper after wiping.
The stool was golden yellow.
Doctor, what could be the cause of this? Should I arrange for a colonoscopy? 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 improve bowel habits, and warm sitz baths can also be helpful.
Over-the-counter hemorrhoid suppositories can be purchased for relief.
If symptoms persist without improvement, it is advisable to consult a physician for further evaluation.

Rectal bleeding can be a concerning symptom, and understanding its potential causes is essential for determining the appropriate course of action. Based on your description, it seems that you are experiencing some discomfort during bowel movements, along with the presence of blood on the toilet paper and occasionally on the stool itself. The fact that the blood is bright red and that you have had some pain suggests that the source of the bleeding is likely to be in the lower gastrointestinal tract, possibly related to the rectum or anus.

One of the most common causes of rectal bleeding, especially in individuals who experience pain during bowel movements, is hemorrhoids. Hemorrhoids are swollen veins in the lower rectum or anus that can cause discomfort, itching, and bleeding, particularly during bowel movements. The bright red blood you see is typically indicative of bleeding from the lower gastrointestinal tract, which is consistent with hemorrhoids. Other potential causes include anal fissures, which are small tears in the lining of the anus that can occur due to passing hard stools, and can also lead to pain and bleeding.

Given that you mentioned the blood on the toilet paper has decreased and that you experienced pain initially but not during your last bowel movement, it may suggest that the issue is resolving on its own. However, it is important to monitor your symptoms closely. If the bleeding persists, worsens, or if you experience additional symptoms such as significant pain, changes in bowel habits, or any signs of systemic illness (like fever or weight loss), it would be prudent to seek medical evaluation.

Regarding the need for a colonoscopy, it is generally recommended to consider this procedure if there are concerning features such as significant or persistent bleeding, a change in bowel habits, or if you are over the age of 50, as this is the age at which screening for colorectal cancer typically begins. In your case, since the bleeding appears to be minor and has decreased, you may not need a colonoscopy immediately, but it would be wise to discuss your symptoms with a healthcare provider who can assess your situation more thoroughly.

In the meantime, here are some general recommendations to help manage your symptoms:
1. Dietary Changes: Increase your fiber intake by consuming more fruits, vegetables, and whole grains. This can help soften your stool and reduce straining during bowel movements, which may alleviate discomfort and prevent further irritation.

2. Hydration: Ensure you are drinking plenty of fluids, as staying hydrated can help maintain softer stools.

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

4. Warm Baths: Taking warm baths can help soothe the area and relieve discomfort.

5. Over-the-Counter Treatments: There are various over-the-counter creams and ointments available for hemorrhoids that may provide relief from itching and discomfort.

If your symptoms do not improve or if you have any concerns, please do not hesitate to reach out to a healthcare professional. They can provide a thorough examination and determine if further diagnostic testing, such as a colonoscopy, is necessary. Remember, it is always better to err on the side of caution when it comes to your health.
