Bowel Issues: What Your Stool Shape Says About Your Health - Gastroenterology and Hepatology

Bowel issues?


Hello, Dr.
Chen.
Today, while using the toilet brush to lift the stool for observation, I noticed that the cross-section (short side) of the stool had a groove-like mark.
When I tried to lift it again for confirmation, it broke into two pieces at the marked area, making it impossible to observe further.
I am really worried because last month I experienced gastrointestinal discomfort and diarrhea, and I consulted a colorectal surgeon.
After a digital rectal examination and a flexible sigmoidoscopy (the type with a soft tube inserted through the anus that displays internal images on a screen), I was diagnosed with internal hemorrhoids.
Could you please advise what this situation might indicate? Is it still considered normal?

Internal hemorrhoids are still considered normal and can be monitored further.

When it comes to bowel health, the shape, consistency, and frequency of your stool can provide valuable insights into your overall digestive health. The presence of grooves or irregularities in your stool, as you described, can be concerning, especially when combined with previous gastrointestinal issues such as diarrhea.
From your description, it seems you have experienced some gastrointestinal discomfort and have been diagnosed with internal hemorrhoids. Hemorrhoids can indeed affect stool shape and consistency. When you have hemorrhoids, the pressure in the rectal area can lead to changes in how stool is expelled, potentially causing it to take on a more irregular shape or to have grooves. This is often due to the stool being forced past swollen veins or tissue, which can create indentations or splits in the stool.

The fact that you noticed a groove or indentation on the short side of your stool could indicate that the stool is being shaped by the surrounding structures in the rectum or anus. This is not uncommon, especially in individuals with hemorrhoids, as the swollen tissue can create a narrower passage for stool to pass through, leading to changes in its shape.
However, it’s important to consider other factors as well. For instance, if you have been experiencing diarrhea, the consistency of your stool can also be affected by the rapid transit time through the intestines. When stool moves quickly through the digestive tract, it may not have enough time to form properly, leading to softer, less defined shapes.
In terms of your concerns about potential underlying conditions, it’s essential to remember that while irregular stool shapes can be a sign of issues such as hemorrhoids or other benign conditions, they can also be indicative of more serious gastrointestinal disorders. However, the likelihood of serious conditions such as colorectal cancer in a young individual is relatively low, especially if you are otherwise healthy and do not have significant risk factors.

Given your history of gastrointestinal discomfort and the recent changes in your stool, it would be prudent to follow up with your healthcare provider. They may recommend further evaluation, such as imaging studies or additional diagnostic tests, to rule out any underlying conditions. It’s also important to maintain a healthy diet rich in fiber, stay hydrated, and manage stress, as these factors can significantly impact bowel health.

In summary, while the presence of grooves in your stool can be concerning, it is often related to benign conditions such as hemorrhoids or changes in stool consistency due to diarrhea. However, ongoing symptoms or changes in bowel habits should always be discussed with a healthcare professional to ensure proper evaluation and management. Regular check-ups and open communication with your doctor can help you maintain optimal digestive health and address any concerns you may have.
