Bleeding from the rectum: related issues?


Dear Director, after using the restroom, I experience sharp pain and cracking in my buttocks.
Following that, even when I'm not using the restroom, I notice blood when I wipe.
After a few wipes, the bleeding stops.
However, not long after that, when I think to wipe again, I see blood again, even though there is no stool.
I would like to ask what the issue might be.
Thank you.

Based on your description, it seems more like a typical symptom of an anal fissure, which is characterized by pain during bowel movements accompanied by slight bleeding.
The pain usually lasts for several days, sometimes exceeding a week.
The common causes are often constipation or diarrhea.
The fundamental treatment is to improve bowel habits, along with warm sitz baths.
Warm sitz baths can help alleviate pain, maintain cleanliness, and promote blood circulation.
You can also purchase hemorrhoid suppositories at the pharmacy for use.
If symptoms persist without improvement, it is advisable to consult a physician for further examination.

Rectal bleeding can be concerning, and it’s important to understand the potential causes and when to seek medical attention. Based on your description, it seems you are experiencing bleeding after bowel movements, accompanied by pain and occasional bleeding when wiping. Here are some possible causes and considerations regarding your symptoms.


Possible Causes of Rectal Bleeding
1. Hemorrhoids: One of the most common causes of rectal bleeding is hemorrhoids, which are swollen veins in the rectal area. They can be internal or external and may cause pain, itching, and bleeding, especially during bowel movements. The blood is usually bright red and may be seen on toilet paper or in the toilet bowl.

2. Anal Fissures: An anal fissure is a small tear in the lining of the anus, often caused by passing hard stools or straining during bowel movements. This can lead to sharp pain during and after bowel movements, as well as bleeding. The blood is typically bright red and may be seen on toilet paper or in the stool.

3. Diverticular Disease: Diverticulosis, which involves the formation of small pouches in the colon wall, can lead to diverticulitis if these pouches become inflamed. This condition can cause bleeding, abdominal pain, and changes in bowel habits.

4. Inflammatory Bowel Disease (IBD): Conditions such as Crohn's disease or ulcerative colitis can cause inflammation in the gastrointestinal tract, leading to symptoms like abdominal pain, diarrhea, and rectal bleeding.

5. Polyps or Colorectal Cancer: While less common, polyps (growths on the colon lining) or colorectal cancer can cause rectal bleeding. This is more likely if you have other symptoms such as changes in bowel habits, unexplained weight loss, or a family history of colorectal cancer.

6. Infections: Certain infections can cause inflammation and bleeding in the gastrointestinal tract. This can be due to bacterial, viral, or parasitic infections.


When to Seek Medical Attention
While minor bleeding due to hemorrhoids or anal fissures may not require immediate medical attention, you should consult a healthcare provider if you experience any of the following:
- Persistent Bleeding: If the bleeding continues or worsens over several days.

- Severe Pain: If you experience significant pain that does not improve.

- Changes in Bowel Habits: If you notice changes in your bowel habits, such as diarrhea or constipation that lasts more than a few days.

- Other Symptoms: If you have additional symptoms such as fever, weight loss, or fatigue.


Recommendations
1. Dietary Changes: Increasing fiber intake can help soften stools and reduce straining during bowel movements, which may alleviate symptoms related to hemorrhoids and fissures.

2. Hydration: Drinking plenty of water can help prevent constipation.

3. Over-the-Counter Treatments: For hemorrhoids, topical treatments or suppositories may provide relief. For fissures, sitz baths can help soothe the area.

4. Avoid Straining: When using the bathroom, try to relax and avoid straining, which can exacerbate bleeding and pain.

5. Consult a Healthcare Provider: Given your symptoms, it would be wise to see a healthcare provider for a thorough evaluation. They may perform a physical examination and possibly recommend further tests, such as a colonoscopy, to determine the underlying cause of your bleeding.

In conclusion, while rectal bleeding can often be attributed to benign conditions like hemorrhoids or anal fissures, it is essential to monitor your symptoms and seek medical advice if they persist or worsen. Early diagnosis and treatment can help manage any underlying issues effectively.
