Persistent urge to defecate without producing stool?


Hello, Doctor! I would like to ask you a few questions.
Recently, I have been experiencing frequent urges to have a bowel movement, and I’ve noticed that when I use a sitting toilet, my stools tend to be smaller, about the size of my thumb.
Additionally, I do not have any abdominal pain or other abnormalities, and the color of my stools is very normal.
There was a period when I noticed bright red blood in my stools, but that has not occurred recently.
However, I still have a sensation of something being present at the anus, which makes me feel like I need to have a bowel movement.
I previously visited a gastroenterology clinic where the doctor diagnosed me with internal hemorrhoids, but I have not undergone a colonoscopy.
Could you please tell me what might be causing these symptoms? Can internal hemorrhoids lead to these conditions? Furthermore, my parents and grandparents do not have a history of colorectal cancer.
Do you think I need to undergo further examinations?

Hello: The likelihood of it being a mole or skin lesion is higher, but if there is persistent rectal bleeding that is increasing in frequency, further examination is necessary.
However, this should be assessed by a clinical physician.
You may consider consulting a gastroenterologist or a colorectal specialist.
If the stools are narrower, it may be advisable to prioritize increasing dietary fiber to see if the situation improves.

More Info


The persistent urge to defecate can be a distressing symptom, and it’s important to understand the potential causes and when to seek medical help. Based on your description, it seems you are experiencing a combination of sensations and symptoms that could be related to several gastrointestinal issues, including the presence of hemorrhoids (internal hemorrhoids, in your case) and possibly other functional bowel disorders.


Possible Causes
1. Internal Hemorrhoids: As you mentioned, you have been diagnosed with internal hemorrhoids. These can cause a sensation of fullness or pressure in the rectal area, leading to a frequent urge to defecate. Hemorrhoids can also cause changes in bowel habits, including the size and consistency of stools. The fact that your stools are smaller in diameter could be related to the presence of hemorrhoids, which can narrow the anal canal.

2. Functional Bowel Disorders: Conditions such as Irritable Bowel Syndrome (IBS) can lead to symptoms like an urgent need to defecate, changes in stool form, and discomfort without significant pain. IBS is often triggered by stress, dietary factors, or changes in gut flora.

3. Anxiety and Stress: Psychological factors can also contribute to gastrointestinal symptoms. Anxiety can lead to increased bowel motility, resulting in a frequent urge to defecate. If you are experiencing stress or anxiety, it may be worthwhile to consider this as a contributing factor.

4. Dietary Factors: Your diet can significantly affect bowel habits. A diet low in fiber can lead to smaller, harder stools and may contribute to the sensation of incomplete evacuation. Conversely, a high-fiber diet can help regulate bowel movements.

5. Rectal Prolapse or Other Anorectal Conditions: In some cases, conditions such as rectal prolapse or other structural issues can cause a sensation of fullness or the urge to defecate.

When to Seek Help
Given your symptoms, especially the persistent urge to defecate and the history of rectal bleeding, it is advisable to seek further medical evaluation. Here are some specific indicators for when to consult a healthcare provider:
- Persistent Symptoms: If the urge to defecate continues for more than a few days without improvement.

- Changes in Bowel Habits: Any significant changes in the frequency, consistency, or appearance of your stools.

- Bleeding: Although you mentioned that the bleeding has stopped, any recurrence of blood in the stool should be evaluated promptly.

- Pain or Discomfort: If you begin to experience abdominal pain, significant discomfort, or any other new symptoms.

- Family History: While you noted that there is no family history of colorectal cancer, it’s still important to discuss your symptoms with a healthcare provider, especially if they persist.


Recommended Actions
1. Consult a Gastroenterologist: Since you have a history of internal hemorrhoids and are experiencing new symptoms, a gastroenterologist can provide a thorough evaluation. They may recommend a colonoscopy to rule out any other underlying conditions, especially given your previous symptoms of rectal bleeding.

2. Dietary Adjustments: Consider increasing your fiber intake through fruits, vegetables, and whole grains. Staying hydrated is also crucial for maintaining regular bowel movements.

3. Monitor Symptoms: Keep a diary of your bowel habits, including the frequency, consistency, and any associated symptoms. This information can be helpful for your healthcare provider.

4. Stress Management: If you suspect that anxiety or stress may be contributing to your symptoms, consider exploring relaxation techniques, counseling, or other stress management strategies.

In conclusion, while internal hemorrhoids can certainly contribute to your symptoms, it is essential to rule out other potential causes. Seeking medical advice is the best course of action to ensure proper diagnosis and treatment.
