Red Mucus in Stool: When to Seek Medical Advice - Gastroenterology and Hepatology

In the past two days, there has been a layer of light red mucus in the stool?

Hello, Doctor.
My lifestyle habits are as follows: 1.
I had a health check-up at National Taiwan University Hospital a year and a half ago, which included a colonoscopy and gastroscopy, and the results were normal.
(I went for the check-up at that time due to similar symptoms that had been recurring for several weeks; the clinic doctor suggested it was caused by an external hemorrhoid, but I wanted to be sure, so I underwent the colonoscopy.) 2.
I have a regular bowel movement almost every day, occasionally every two days.
3.
I do not experience abdominal pain, diarrhea, or other gastrointestinal discomfort.
The stool consistency is normal.
There is no sharp pain associated with anal fissures.
4.
Occasionally, I experience a sensation of chest tightness similar to gastroesophageal reflux, and sometimes I have prolonged bouts of burping.
(I enjoy drinking coffee and tea.) 5.
I have an external hemorrhoid.
In the past two days, after having a bowel movement in the morning (without any sensation of straining), I noticed a red-brown mucus on the surface of one stool, approximately the size of a coin (not bright red blood).
The color was visible to the naked eye, and I confirmed it had a blood-like hue when I dabbed it with tissue.
I feel somewhat anxious and would like to ask you, Doctor, given that I had a normal colonoscopy a year and a half ago, can I rule out the possibility of colon cancer at this point? How long should I wait before undergoing another colonoscopy? How long should I monitor these symptoms before seeking medical attention? Thank you, Doctor, and I apologize for bothering you!

Hello, Miss.
The likelihood of colorectal cancer is low.
You can start with monitoring and observation (plus taking photos with your phone for the physician's reference).
You may also consider a fecal occult blood test.
Changhua Hospital cares about your health.

When it comes to understanding the presence of red mucus in stool, it's essential to approach the situation with caution and awareness of potential underlying issues. Based on your description, you have a history of normal colonoscopy results and no significant gastrointestinal symptoms, which is reassuring. However, the appearance of red mucus in your stool warrants further consideration.

Firstly, it’s important to clarify that the presence of red mucus can be indicative of several conditions. While it may be related to benign issues such as hemorrhoids or anal fissures, it can also signify more serious conditions like inflammatory bowel disease (IBD), infections, or even colorectal cancer, particularly if accompanied by other symptoms. Given that you have not experienced abdominal pain, diarrhea, or other gastrointestinal discomfort, this may suggest a less severe issue, but it does not completely rule out the need for further evaluation.

Your previous colonoscopy, which was normal, does provide some reassurance regarding the likelihood of colorectal cancer at this time. However, it is crucial to remember that while colonoscopy is an effective screening tool, it does not eliminate the possibility of developing new conditions or changes in the bowel since your last examination. The general recommendation for average-risk individuals is to undergo screening colonoscopy every ten years, but this can vary based on personal and family medical history, as well as the presence of any new symptoms.

In your case, since you have noted the presence of red mucus only recently and have not experienced any other alarming symptoms, it may be reasonable to monitor the situation for a short period. If the mucus persists for more than a few days, or if you start to experience any additional symptoms such as changes in bowel habits, abdominal pain, weight loss, or any other concerning signs, it would be prudent to seek medical advice promptly.

In terms of lifestyle factors, you mentioned experiencing gastroesophageal reflux symptoms and frequent hiccups, which could be related to dietary habits, such as your coffee and tea consumption. While these symptoms may not directly relate to the mucus in your stool, they could indicate a broader gastrointestinal sensitivity that might warrant attention.

In summary, while your previous normal colonoscopy is reassuring, the appearance of red mucus in your stool should not be ignored. If the symptom persists beyond a few days, or if you develop any additional concerning symptoms, it is advisable to consult with a healthcare professional. They may recommend further evaluation, which could include a repeat colonoscopy or other diagnostic tests to rule out any underlying conditions. Always trust your instincts regarding your health, and do not hesitate to seek medical advice when something feels off. Your health is paramount, and proactive management is key to ensuring your well-being.
