Flat-shaped stool
Hello doctor, I have been experiencing chronic diarrhea.
Previously, I was diagnosed with irritable bowel syndrome, and after taking traditional Chinese medicine, my diarrhea improved.
However, I recently noticed that my stools are only slightly thicker than my thumb, and I have had two instances of flat-shaped stools.
I would like to know if this condition could be indicative of cancer.

The narrowing of stools caused by colorectal cancer will progressively become thinner; it will not fluctuate between thin and thick.

More Info
Flat stools can be a concerning symptom, especially when accompanied by a history of gastrointestinal issues such as irritable bowel syndrome (IBS). While it is understandable to worry about the possibility of serious conditions like cancer, it is essential to consider various factors before jumping to conclusions.
Firstly, flat stools can occur for several reasons. In many cases, they may be related to benign conditions such as dietary changes, dehydration, or stress. For individuals with IBS, changes in stool shape and consistency can be common due to the nature of the disorder, which affects how the intestines function. The presence of flat stools, particularly if they are not consistently flat, may not necessarily indicate a serious problem.
However, persistent changes in stool shape, especially if they become consistently flat or ribbon-like, warrant further investigation. This is because flat stools can sometimes be associated with conditions that cause narrowing of the intestinal lumen, such as colorectal cancer or other obstructive lesions. It is crucial to differentiate between benign causes and those that may require medical attention.
Given your history of IBS and the recent changes in your stool, it is advisable to consult with a healthcare professional, preferably a gastroenterologist. They may recommend further diagnostic tests, such as a colonoscopy, to evaluate the condition of your intestines and rule out any serious underlying issues. A colonoscopy is a safe and effective procedure that allows direct visualization of the colon and can help identify any abnormalities, including polyps or tumors.
In addition to seeking medical advice, consider keeping a detailed record of your symptoms, including the frequency and consistency of your stools, any accompanying symptoms (such as abdominal pain, weight loss, or changes in appetite), and any dietary changes you have made. This information can be valuable for your healthcare provider in making an accurate diagnosis.
While it is natural to be concerned about the possibility of cancer, it is essential to remember that many factors can contribute to changes in stool shape and consistency. Early intervention and thorough evaluation are key to addressing any potential issues. If your symptoms persist or worsen, do not hesitate to seek medical attention promptly.
In summary, while flat stools can be a sign of digestive issues, they are not automatically indicative of cancer. Given your history of IBS and recent changes, it is crucial to consult with a healthcare professional for a comprehensive evaluation. Early diagnosis and appropriate management can help alleviate your concerns and ensure your digestive health is well monitored.
