Unusual Stool Shape: Should You Be Concerned About Your Health?

Abnormal stool shape?

Hello Doctor, I recently noticed that one side of my stool is flat, resembling a spoon or knife, but the color is normal and there is no blood.
I occasionally experience diarrhea but rarely have constipation.
I'm wondering if this is a dangerous sign that requires immediate examination.
Additionally, I had my gallbladder removed four years ago due to polyps.
Can you tell me if patients who have had their gallbladder removed are truly at a higher risk for colorectal cancer? I appreciate your time in addressing my concerns.
Thank you very much.

1.
If there are hemorrhoids, this condition may occur during bowel movements due to the hemorrhoidal tissue occupying the anal opening.
Of course, low rectal cancer could also present with similar symptoms, but the probability is relatively low.
If there are concerns, it is advisable to have a physician perform a digital rectal examination or a flexible sigmoidoscopy to differentiate the conditions.
2.
As far as I know, cholecystectomy is not related to the occurrence of colorectal cancer.
After researching relevant information, I found that this is a claim originating from the Chinese region, with its original source being a clinical study from the UK.
The results of 119 in 100,000 and 86 in 100,000 do not appear to be statistically significant.
The authors also believe that further research is needed to confirm this, and it may have been misinterpreted or miscommunicated in that context.

More Info

When it comes to unusual stool shapes, such as the flat, spoon-like appearance you've described, it can indeed be a cause for concern, but it is essential to consider the context and other symptoms. The shape of your stool can provide insights into your gastrointestinal health. Flat stools can sometimes indicate a narrowing of the colon, which could be due to various reasons, including inflammation, strictures, or even tumors. However, the absence of blood and the normal color of your stool are positive signs.

Given your history of gallbladder removal due to polyps, it is understandable to be vigilant about changes in your bowel habits. While gallbladder removal itself does not directly increase the risk of colorectal cancer, individuals with a history of polyps are at a higher risk for developing colorectal cancer. Polyps are growths on the lining of the colon that can become cancerous over time, so regular screenings, such as colonoscopies, are crucial for monitoring and preventing potential issues.

In your case, the occasional diarrhea and infrequent constipation may suggest some degree of gastrointestinal instability, which could be related to dietary factors, stress, or other underlying conditions. It is important to maintain a balanced diet rich in fiber, stay hydrated, and manage stress levels, as these factors can significantly affect bowel health.

Given your symptoms and medical history, it would be prudent to consult with a healthcare professional. They may recommend further evaluation, such as a colonoscopy, to assess the condition of your colon and rule out any serious issues. Early detection is key in managing potential health concerns, especially with your history of polyps.

In summary, while the unusual shape of your stool can be a signal to pay attention to your health, it is essential to consider it alongside other symptoms and your medical history. Regular check-ups and screenings are vital, especially for individuals with a history of gastrointestinal issues. Don't hesitate to reach out to your healthcare provider for a thorough evaluation and personalized advice. Your health is paramount, and addressing these concerns early can lead to better outcomes.
