Abdominal Pain and Mucus in Stool: When to Seek a Colonoscopy - Surgery

Lower abdominal pain with clear mucus containing blood streaks?


Hello, doctor.
I have always had a tendency towards constipation, but two weeks ago I started experiencing diarrhea, accompanied by lower abdominal pain.
I also noticed that my stool has become thinner, with a transparent mucus coating and some blood streaks.
Sometimes, there is also a white, membrane-like substance.
Although I underwent a digital rectal examination and the doctor said it was due to hemorrhoids, I am still experiencing diarrhea.
Should I consider getting a colonoscopy?

Because you have blood in your stool along with several other abnormal symptoms, it is recommended that you visit the hospital for a colonoscopy.

More Info


Abdominal pain and changes in bowel habits can be concerning, especially when accompanied by mucus in the stool and blood. Your symptoms, including persistent diarrhea, abdominal pain, and the presence of mucus and blood in your stool, warrant further investigation. While your doctor has suggested that hemorrhoids (痔瘡) may be the cause of your symptoms, it is essential to consider other potential underlying conditions that could be contributing to your discomfort.


Understanding Your Symptoms
1. Mucus and Blood in Stool: The presence of mucus in your stool, especially when accompanied by blood, can indicate several gastrointestinal issues. Mucus is a normal component of stool, but an increase in mucus production can be a sign of inflammation in the intestines. Blood in the stool can arise from various sources, including hemorrhoids, but it can also indicate more serious conditions such as inflammatory bowel disease (IBD), infections, or even colorectal cancer, particularly given your family history of colorectal cancer.

2. Changes in Bowel Habits: The transition from constipation to diarrhea, along with abdominal pain, can suggest a functional gastrointestinal disorder, such as irritable bowel syndrome (IBS), or an inflammatory condition like IBD (Crohn's disease or ulcerative colitis). The fact that your stool has become thinner and is accompanied by mucus and blood raises the concern for possible inflammation or irritation of the intestinal lining.

3. Abdominal Pain: The location and nature of your abdominal pain can provide clues about the underlying issue. Pain associated with bowel movements, especially if it is relieved after a bowel movement, can be indicative of conditions affecting the colon.


When to Consider a Colonoscopy
Given your symptoms and the potential for serious underlying conditions, a colonoscopy may be warranted for several reasons:
- Persistent Symptoms: If your symptoms persist despite treatment for hemorrhoids, or if they worsen, a colonoscopy can help identify any underlying issues that may not be visible through other diagnostic methods.


- Family History: Your family history of colorectal cancer is a significant risk factor. Individuals with a family history of colorectal cancer are often advised to undergo screening earlier and more frequently than the general population.

- Red Flags: Symptoms such as significant weight loss, severe abdominal pain, or changes in bowel habits that last more than a few weeks should prompt further investigation. The presence of blood in the stool, especially if it is new or different from your usual symptoms, is also a red flag.


Conclusion
In summary, while hemorrhoids may be contributing to your symptoms, the presence of mucus and blood in your stool, along with changes in bowel habits, suggests that further evaluation is necessary. A colonoscopy is a valuable diagnostic tool that can help identify or rule out conditions such as IBD, infections, or even malignancies. It is essential to discuss your concerns with your healthcare provider, who can evaluate your symptoms in the context of your medical history and family history and determine the most appropriate course of action. Early detection and intervention are crucial for managing gastrointestinal conditions effectively, so do not hesitate to seek further evaluation.
