Anal Blockages: Symptoms, Causes, and Concerns

Regarding the issue of anal obstruction?

Hello Doctor, I recently discovered a lump inside my anus (it's difficult to insert a finger), and I have a sensation that my anus is almost blocked.
However, there is no bleeding when I use the restroom, and it doesn't hurt much; I only feel a foreign body sensation when walking.
Could this be a hemorrhoid? Additionally, can hemorrhoids cause thin stools? Thank you.

At this age, anal masses are typically related to hemorrhoids.
Swollen hemorrhoids can cause stool to become narrower, and the underlying causes are often associated with poor bowel habits and dietary practices.
It is recommended to avoid constipation during this period and to shorten the time spent on the toilet.
Warm sitz baths may also help alleviate symptoms.
Over-the-counter hemorrhoid suppositories can be used, but laxatives should be taken with caution.
Increasing the intake of dietary fiber and fluids should generally be sufficient at this age.

More Info

Understanding anal blockages can be quite concerning, especially when symptoms like a lump or a feeling of obstruction arise. Based on your description, it sounds like you are experiencing a growth or mass in the anal area, which is causing a sensation of blockage but is not accompanied by bleeding or significant pain.
Firstly, it’s important to clarify that the term "庤瘡" (which translates to "ulcer" in English) typically refers to an open sore or lesion. While anal ulcers can occur, they usually present with pain, discomfort, and sometimes bleeding. The lump you are feeling may not necessarily be an ulcer but could be a hemorrhoid, anal fissure, or even a benign growth such as a polyp or a skin tag. Hemorrhoids, for instance, are swollen blood vessels in the rectal area that can cause discomfort and a sensation of fullness or blockage, especially if they become thrombosed (clotted).

Regarding your question about whether an anal ulcer can lead to changes in bowel movements, it is possible. Anal ulcers can cause pain during bowel movements, which may lead to constipation as individuals may avoid passing stool due to fear of pain. This can result in harder stools that are more difficult to pass, potentially leading to a feeling of blockage. However, if you are not experiencing pain or bleeding, it may be less likely that you have an ulcer.

The sensation of a blockage can also be attributed to other conditions, such as:
1. Hemorrhoids: These can cause a feeling of fullness or pressure in the anal area. They can be internal or external and may not always cause pain or bleeding.

2. Anal Fissures: While these are typically painful, they can also lead to a sensation of tightness or blockage.

3. Anal Abscess: This is a collection of pus that can occur near the anus and may cause swelling and discomfort.

4. Anal Polyps or Skin Tags: These are usually benign growths that can create a sensation of obstruction.

5. Fecal Impaction: This occurs when stool becomes hard and difficult to pass, leading to a blockage sensation.

Given your symptoms, it is crucial to consult a healthcare professional for a proper evaluation. A physical examination, possibly including a digital rectal exam, can help determine the nature of the lump and the appropriate course of action.
In the meantime, it may be helpful to monitor your bowel habits, including the consistency of your stools and any changes in your symptoms. Staying hydrated, consuming a high-fiber diet, and avoiding straining during bowel movements can help maintain regularity and may alleviate some discomfort.

In summary, while the lump you are experiencing may not necessarily be an ulcer, it is essential to seek medical advice to determine the exact cause of your symptoms and to receive appropriate treatment. Early intervention can help prevent complications and improve your overall comfort and health.
