Rectal bleeding


Hello doctor, recently I've noticed that there is sometimes blood on the toilet paper after I have a bowel movement, and sometimes there isn't.
When the toilet paper doesn't have blood on it, I sometimes wipe inside the anal area with the toilet paper and find blood.
The amount of blood is not much, it looks like a small abrasion.
I haven't seen any blood in my stool.
This situation has been going on for several days, and I'm a bit worried if this could be a sign of colorectal disease.

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.
Mild bleeding from hemorrhoids can also present similarly.
The common causes are often constipation or diarrhea.
The fundamental treatment is to improve bowel habits, along with warm sitz baths.
You can also purchase hemorrhoid suppositories at the pharmacy for relief.
If symptoms persist without improvement, it is advisable to consult a physician.
If the symptoms continue to be unresolved, a colonoscopy may also be necessary.

Rectal bleeding can be a concerning symptom, and it's important to understand its potential causes and when to seek medical help. Based on your description, it sounds like you are experiencing intermittent bleeding after bowel movements, which is sometimes visible on toilet paper but not in the stool itself. This type of bleeding can be caused by several factors, and while it may not always indicate a serious condition, it is essential to monitor the situation closely.

One common cause of rectal bleeding, especially if the blood is bright red and appears on toilet paper, is hemorrhoids. Hemorrhoids are swollen blood vessels in the rectal area that can become inflamed or irritated, often due to straining during bowel movements, constipation, or prolonged sitting. They can cause discomfort, itching, and bleeding, particularly during or after a bowel movement. Another possibility is anal fissures, which are small tears in the lining of the anus that can occur due to passing hard stools. These fissures can be quite painful and may also lead to bleeding.

In some cases, rectal bleeding can be associated with more serious conditions, such as diverticular disease, inflammatory bowel disease (IBD), or colorectal polyps and cancer. While the likelihood of these conditions increases with age or if there are other concerning symptoms (such as significant weight loss, changes in bowel habits, or abdominal pain), it is crucial not to dismiss any instance of rectal bleeding without proper evaluation.

Given that you have been experiencing this symptom for several days, it is advisable to consult a healthcare professional. A doctor can perform a thorough evaluation, which may include a physical examination and possibly a rectal exam. Depending on the findings, they may recommend further diagnostic tests such as a colonoscopy, especially if there are risk factors for colorectal cancer or if the bleeding persists.

In the meantime, here are some general recommendations to help manage your symptoms and promote rectal health:
1. Dietary Changes: Increase your fiber intake by consuming more fruits, vegetables, and whole grains. This can help soften stools and reduce straining during bowel movements. Staying well-hydrated by drinking plenty of water is also essential.

2. Avoid Straining: If you experience constipation, consider using over-the-counter stool softeners or laxatives as directed by a healthcare provider. Avoid straining during bowel movements, as this can exacerbate hemorrhoids or fissures.

3. Warm Baths: Taking warm baths can help soothe the anal area and alleviate discomfort associated with hemorrhoids or fissures.

4. Avoid Prolonged Sitting: If you have a sedentary lifestyle, try to take breaks and move around periodically to reduce pressure on the rectal area.

5. Monitor Symptoms: Keep track of any changes in your symptoms, including the frequency and amount of bleeding, as well as any new symptoms that may arise.

In conclusion, while rectal bleeding can often be attributed to benign causes such as hemorrhoids or anal fissures, it is essential to seek medical advice to rule out more serious conditions. Early evaluation and intervention can lead to better outcomes and peace of mind. If you notice any alarming symptoms, such as significant bleeding, severe pain, or changes in bowel habits, do not hesitate to seek immediate medical attention.
