Stool with mucus?


Hello Doctor: I previously experienced pain in the lower right abdomen that lasted for almost two to three months.
A colorectal surgeon arranged for a barium study, but the results showed no issues.
Later, I consulted a gastroenterologist who performed an endoscopy and found gastric ulcers and duodenitis.
I was prescribed medication for chronic conditions, which I have been taking for about five months now! Shortly after, I noticed some abnormalities in my stool; it sometimes contained mucus and occasionally blood streaks.
I’m not sure how long this has been happening, but I think it has been two to three months since I first noticed it! I underwent a colonoscopy, which showed no problems.
I had the procedure done without sedation, but I didn’t ask how far the scope went.
My stool still has mucus and sometimes blood streaks! I had my examinations at Mackay Memorial Hospital in Taipei, and the results were all normal.
The doctor told me not to worry and suggested it might be internal hemorrhoids, with no signs of inflammation in the colon.
However, I am still quite concerned, especially since my stool consistently has mucus and blood streaks! This situation makes it difficult for me to work with peace of mind! Doctor, what should I do???? (Note: The mucus varies in amount, sometimes more, sometimes less; it is white with a hint of yellow and sometimes clear.)

Dr. Hou Yongji reply Surgery


Based on your description, a proper diagnosis cannot be made.
Please consult a colorectal surgeon for evaluation (remember to bring copies of your examination reports, and it’s best to include photos or imaging).
Thank you.

Understanding mucus in stool can be concerning, especially when accompanied by other symptoms such as abdominal pain or blood. Mucus is a normal component of stool, produced by the intestines to lubricate and protect the lining of the gastrointestinal tract. However, when there is an increase in mucus or the presence of blood, it can indicate an underlying issue that may require further investigation.

In your case, you have experienced abdominal pain, which led to various diagnostic tests including a barium study and an endoscopy, revealing a gastric ulcer and duodenitis. You were prescribed medication for chronic management, which is a common approach for such conditions. However, the subsequent discovery of mucus in your stool, sometimes with blood streaks, is understandably alarming.

The presence of mucus in stool can be caused by several factors, including:
1. Irritable Bowel Syndrome (IBS): This functional gastrointestinal disorder can lead to increased mucus production, often accompanied by abdominal pain, bloating, and changes in bowel habits.

2. Inflammatory Bowel Disease (IBD): Conditions like Crohn's disease or ulcerative colitis can cause inflammation in the intestines, leading to increased mucus and sometimes blood in the stool. Although your colonoscopy did not show signs of inflammation, it is important to consider that IBD can sometimes be patchy and may not always be detected in a single examination.

3. Infections: Gastrointestinal infections can lead to increased mucus production as the body attempts to flush out pathogens. This can also cause diarrhea, abdominal pain, and sometimes blood in the stool.

4. Hemorrhoids or Anal Fissures: These conditions can cause blood in the stool, especially if there is straining during bowel movements. They can also lead to mucus discharge.

5. Dietary Factors: Certain foods can irritate the gut lining or lead to increased mucus production. Keeping a food diary may help identify any potential dietary triggers.

Given that your colonoscopy results were normal and your doctor suggested that the mucus could be related to internal hemorrhoids, it is essential to consider follow-up care. While your doctor has reassured you, persistent symptoms warrant further evaluation, especially since you have been experiencing these symptoms for several months.

Here are some recommendations for managing your situation:
1. Follow-Up with Your Gastroenterologist: If your symptoms persist or worsen, it is crucial to return to your gastroenterologist for further evaluation. They may recommend additional tests, such as stool studies or imaging, to rule out other conditions.

2. Monitor Your Symptoms: Keep track of any changes in your bowel habits, the frequency of mucus or blood in your stool, and any associated symptoms like pain or changes in appetite. This information can be valuable for your healthcare provider.

3. Dietary Adjustments: Consider a diet rich in fiber to promote regular bowel movements and reduce straining. Staying hydrated is also essential. If you suspect certain foods may be contributing to your symptoms, try an elimination diet under the guidance of a healthcare professional.

4. Stress Management: Stress can exacerbate gastrointestinal symptoms, particularly in conditions like IBS. Techniques such as mindfulness, yoga, or counseling may help manage stress levels.

5. Seek Immediate Care if Necessary: If you experience severe abdominal pain, significant blood in your stool, or any other alarming symptoms, seek medical attention promptly.

In conclusion, while the presence of mucus and occasional blood in your stool can be concerning, it is essential to work closely with your healthcare provider to monitor your symptoms and determine the best course of action. Your health and peace of mind are paramount, and addressing these symptoms with a qualified professional is the best way to ensure your well-being.
