Mucus in stool with blood streaks?


Hello Doctor: I have a history of hemorrhoids and occasionally notice white mucus.
In March, I observed pink streaks of blood after wiping following a bowel movement.
A colonoscopy was performed, and the results were normal, indicating that there is something related to the structure of the colon itself.
Due to long-term constipation, I occasionally use a laxative to help with bowel movements.
Today, in June, I had a bowel movement without abdominal pain, but I noticed red streaks of mucus resembling phlegm.
I am unsure if this indicates intestinal inflammation.
Since it has been three months since my last examination, do I need to undergo another colonoscopy?

Dr. Lin Minghui reply Gastroenterology and Hepatology


Hello: The presence of mucus with blood in the stool can be commonly caused by conditions such as colitis, proctitis, anal fissures, hemorrhoids, chronic constipation, or mucosal injury due to the use of laxatives.
If this occurs frequently, it is advisable to undergo a rectal and anal examination.
Wishing you safety and health.
Sincerely, Dr.
Lin Ming-Hui, Attending Physician, Gastroenterology Department, Taoyuan General Hospital, Ministry of Health and Welfare.

When it comes to understanding blood-streaked mucus in stool, it is essential to consider various factors, including the patient's medical history, symptoms, and previous diagnostic results. In your case, you have a history of hemorrhoids and have experienced episodes of blood-streaked mucus in your stool, which can be concerning. However, since you have already undergone a colonoscopy in March that yielded normal results, it is crucial to analyze the current situation carefully.

Blood-streaked mucus in stool can arise from several causes, including hemorrhoids, anal fissures, inflammatory bowel disease (IBD), infections, or even colorectal cancer. Given your history of hemorrhoids, it is possible that the blood you are observing is related to this condition, especially if you have been experiencing constipation and straining during bowel movements. Hemorrhoids can bleed, and the presence of mucus is not uncommon.

However, the appearance of fresh red blood in your stool, especially if it is accompanied by changes in bowel habits or if you notice other concerning symptoms (such as significant weight loss, persistent abdominal pain, or changes in appetite), warrants further investigation. While your previous colonoscopy was normal, the fact that you are now experiencing new symptoms may indicate that a follow-up is necessary.

In general, if you notice any of the following, it is advisable to seek further testing or consultation with a healthcare provider:
1. Persistent Symptoms: If the blood-streaked mucus continues or worsens, or if you develop new symptoms such as abdominal pain, diarrhea, or changes in bowel habits, it is essential to consult a physician.

2. Duration of Symptoms: If you have been experiencing these symptoms for an extended period, it is wise to have them evaluated again, even if a previous colonoscopy was normal.

3. Family History: If there is a family history of colorectal cancer or other gastrointestinal diseases, this may increase your risk and necessitate more frequent screenings.

4. Other Symptoms: If you experience systemic symptoms such as fever, weight loss, or fatigue, these could indicate a more serious underlying condition that requires immediate attention.

In your case, since it has been three months since your last colonoscopy and you are now noticing new symptoms, it may be prudent to discuss your concerns with your healthcare provider. They may recommend repeating the colonoscopy or conducting other diagnostic tests, such as imaging studies or stool tests, to rule out any potential issues.

In conclusion, while your previous colonoscopy was normal, the emergence of new symptoms, particularly blood-streaked mucus, should not be ignored. It is always better to err on the side of caution when it comes to gastrointestinal symptoms. Consulting with a healthcare professional will provide you with the best course of action tailored to your specific situation.
