Rectal bleeding


Recently, I have been having difficulty passing stools, and when I do manage to have a bowel movement, there is bright red blood that comes out before the stool (the blood is separate from the stool).
After the bowel movement, there is a little bit of blood that continues to flow for a while, but it stops within about an hour.
The first time I bled during a bowel movement, there was more blood, and the subsequent times had less blood than the first.
Could you please help me understand this? Thank you.

Hello: In response to your question, at the age of 25, passing fresh blood after a bowel movement is likely due to hemorrhoidal bleeding.
If there are difficulties in bowel movements, this condition may worsen.
It is generally recommended to improve bowel habits and consult a proctologist for some topical treatments.
If symptoms persist, further examination should be conducted.

More Info


Rectal bleeding can be a concerning symptom, and understanding its causes is crucial for determining the appropriate course of action. Based on your description, it appears that you are experiencing bright red blood during bowel movements, which is often indicative of bleeding from the lower gastrointestinal tract, particularly the rectum or anus.
One of the most common causes of rectal bleeding is hemorrhoids, which are swollen veins in the rectal area that can become inflamed and bleed, especially during bowel movements. The blood associated with hemorrhoids is typically bright red and may appear on the toilet paper or in the toilet bowl. Another possible cause could be anal fissures, which are small tears in the lining of the anus that can occur due to passing hard stools. Like hemorrhoids, fissures can cause sharp pain and bleeding during bowel movements.

Other potential causes of rectal bleeding include diverticular disease, which involves the formation of small pouches in the colon that can become inflamed or infected, leading to bleeding. Inflammatory bowel diseases (IBD) such as Crohn's disease or ulcerative colitis can also cause rectal bleeding, along with other symptoms like abdominal pain and diarrhea. Less commonly, rectal bleeding can be a sign of colorectal polyps or cancer, particularly if it is persistent or accompanied by other concerning symptoms such as weight loss, changes in bowel habits, or severe abdominal pain.

Given that you mentioned difficulty with bowel movements and the presence of blood, it is essential to seek medical attention. While some causes of rectal bleeding, such as hemorrhoids, may be benign and manageable, others may require more urgent evaluation and treatment. A healthcare provider may recommend a physical examination, including a digital rectal exam, and possibly further diagnostic tests such as a colonoscopy to visualize the colon and rectum directly.

In terms of when to seek help, you should consider visiting a healthcare professional if:
1. The bleeding is persistent or recurrent.

2. You experience significant pain or discomfort.

3. You notice changes in your bowel habits, such as diarrhea or constipation.

4. You have accompanying symptoms like weight loss, fatigue, or fever.

In the meantime, to help manage your symptoms, consider the following:
- Increase your dietary fiber intake to help soften stools and make bowel movements easier. Foods rich in fiber include fruits, vegetables, whole grains, and legumes.

- Stay well-hydrated by drinking plenty of water throughout the day.

- If you are experiencing pain or discomfort, over-the-counter pain relief medications may help, but consult with a healthcare provider before taking any new medications.

- Avoid straining during bowel movements, as this can exacerbate bleeding and discomfort.

In summary, while rectal bleeding can have various causes, it is essential to take it seriously and consult with a healthcare professional for a thorough evaluation. Early diagnosis and appropriate management can help prevent complications and improve your overall health.
