Swelling Near the Anus During Bowel Movements: What You Should Know - Gastroenterology and Hepatology

During bowel movements, there is a swelling on the right side of the anus?


Hello doctor, after I have a bowel movement, I notice a swelling on the right side of my anus that varies in size.
It tends to be larger after a regular bowel movement (about the size of half a pinky finger), while it only protrudes slightly during diarrhea, and there’s a low chance it won’t swell at all.
I recall experiencing this once after exerting myself (not during a bowel movement).
It feels similar to the example in article #104528, but not exactly the same.
I first noticed this condition back in high school or college, although at that time it was only a slight protrusion.
When I gently press on it, it retracts (without pushing it towards the anus), and there’s no pain during bowel movements, nor have I experienced any bleeding.
I looked up information about hemorrhoids, and it seems my situation is different.
Should I seek medical attention to confirm this condition?

Hello: It should still be classified as a mole or skin lesion.
If there is increased pressure during bowel movements, it may indicate a combination of internal and external lesions.
Additionally, in some cases, it may simply be a skin tag.
If you are still very concerned, you can consult a colorectal specialist or a gastroenterologist for confirmation.

More Info


Swelling near the anus during bowel movements can be concerning, and it's important to understand the potential causes and when to seek medical attention. Based on your description, it sounds like you may be experiencing a condition related to the anal region, possibly involving hemorrhoids or other issues.

Hemorrhoids are swollen veins in the lower rectum and anus that can cause discomfort, itching, and swelling. They can be classified as either internal or external. Internal hemorrhoids are located inside the rectum and are usually not visible, while external hemorrhoids are located under the skin around the anus and can be felt or seen. The swelling you describe, especially if it appears after bowel movements and can be pushed back in, suggests that it could be an external hemorrhoid or possibly a prolapsed internal hemorrhoid.

The fact that you mentioned the swelling varies in size depending on whether you are having a normal bowel movement or diarrhea is also significant. Straining during bowel movements can exacerbate hemorrhoids, leading to increased swelling. Additionally, if you have experienced this condition since high school or college, it may indicate a chronic issue that has not been addressed.

It is reassuring that you do not experience pain during bowel movements or any bleeding, as these symptoms can indicate more serious conditions. However, the presence of swelling alone warrants further evaluation. Other potential causes of anal swelling could include anal fissures, skin tags, or even infections, which may require different treatments.

Given that you have been aware of this condition for several years, it would be wise to consult with a healthcare professional, particularly a gastroenterologist or a colorectal surgeon. They can perform a physical examination and possibly recommend further diagnostic tests, such as an anoscopy, to visualize the anal canal and rectum more clearly. This will help in determining the exact cause of the swelling and whether any treatment is necessary.

In terms of management, if it is indeed hemorrhoids, there are several options available. Conservative treatments include lifestyle modifications such as increasing fiber intake, staying hydrated, and avoiding straining during bowel movements. Over-the-counter topical treatments can also provide relief from symptoms. In more severe cases, medical procedures may be necessary to remove or reduce the hemorrhoids.

In summary, while your symptoms may not indicate a severe condition, it is advisable to seek medical attention to confirm the diagnosis and discuss appropriate treatment options. Early intervention can help prevent the condition from worsening and improve your quality of life. Remember, it’s always better to be cautious when it comes to your health, especially with symptoms that have persisted over time.
