White mucus in stool?


Having white mucus in your stool for three consecutive days, along with the presence of mucus during flatulence, can be concerning.
While these symptoms can be associated with various gastrointestinal issues, they are not definitive indicators of colorectal cancer.
Given that you had a normal flexible sigmoidoscopy 60 cm in on September 1, 2007, it may not be immediately necessary to undergo another colonoscopy.
However, it is important to consult with a healthcare professional to discuss your symptoms further and determine if additional testing is warranted based on your medical history and any other symptoms you may be experiencing.

Hello Miss Hsiao-Wen: It is likely indigestion (Irritable Bowel Syndrome).
You mainly need to adjust your diet and medication; it is not colon cancer (which includes blood in the stool).
Please rest assured.

More Info


When it comes to the presence of white mucus in stool, it is understandable to be concerned about potential underlying health issues, including colon cancer. However, it is important to recognize that the presence of mucus in stool can be attributed to a variety of factors, and not all of them are indicative of serious conditions like cancer.

Mucus is a normal component of stool, produced by the intestines to help lubricate the passage of waste. It can appear more prominently in certain situations, such as during episodes of diarrhea or gastrointestinal irritation. The presence of white mucus, especially if it is accompanied by other symptoms such as abdominal pain, changes in bowel habits, or blood in the stool, may warrant further investigation.

In your case, since you have experienced white mucus in your stool for three consecutive days, it is advisable to monitor the situation closely. If the mucus persists, or if you develop additional symptoms, it would be prudent to consult with a healthcare professional for a thorough evaluation. Given your history of a normal colonoscopy 60 centimeters into the sigmoid colon in September 2007, it is possible that the mucus is related to a benign condition, such as irritable bowel syndrome (IBS), infections, or inflammation of the intestines.

While colon cancer can present with changes in bowel habits, including the presence of mucus, it is more commonly associated with symptoms such as blood in the stool, unexplained weight loss, persistent abdominal discomfort, or a change in the caliber of the stool. The fact that your previous colonoscopy was normal is reassuring, but it does not completely rule out the possibility of developing new issues since then.

If you are considering whether to undergo another colonoscopy, factors such as your age, family history of colorectal cancer, and any new symptoms should be taken into account. The general recommendation is that individuals at average risk for colorectal cancer begin screening at age 45, with follow-up screenings every ten years if no abnormalities are found. However, if you have risk factors or concerning symptoms, more frequent screening may be warranted.

In summary, while the presence of white mucus in stool can be concerning, it is not automatically indicative of colon cancer. It is essential to consider the context of your overall health, any accompanying symptoms, and your medical history. If you have ongoing concerns, it is best to consult with a healthcare provider who can assess your situation and determine if further diagnostic testing, such as a colonoscopy, is necessary. Early detection and intervention are key in managing any potential gastrointestinal issues effectively.
