Blood in stool, mucus, abdominal pain?


For about three consecutive weeks, I have experienced symptoms of mucus in my stool, bloody stools, and abdominal pain.
I consulted a colorectal specialist who performed a digital rectal exam and an anoscopy.
The doctor mentioned that the "mucus" could be due to excessive consumption of fruits and vegetables, the "bloody stools" were likely caused by excessive wiping at the anal area, leading to injury, and the "abdominal pain" was attributed to a lack of lubrication in the intestines, causing dryness.
The doctor believes that these issues can be improved with changes in lifestyle and diet, and that medication is not necessary.
However, it has been a week since the consultation, and I still experience abdominal pain and mucus.
I would like to ask Dr.
Hsu if I need to undergo a colonoscopy.
Additionally, I have a history of duodenal ulcers; could the aforementioned symptoms be related to my duodenal ulcer? (Thank you for your response.)

I apologize for the delayed response due to the email forwarding process.
Rectal bleeding is considered an abnormal symptom and may range from common conditions like hemorrhoids to more serious gastrointestinal diseases.
However, given that your symptoms are accompanied by persistent mucus and abdominal pain for three weeks, it is essential to be more vigilant.
This may not necessarily be related to a duodenal ulcer.
I recommend that you visit a hospital's surgical or gastroenterology department for further evaluation, including an assessment of the necessity for a colonoscopy.

It sounds like you are experiencing a concerning combination of symptoms: mucus in your stool, blood in your stool, and abdominal pain. These symptoms can be indicative of various gastrointestinal conditions, and while your doctor has provided some explanations, it is important to consider further evaluation, especially since your symptoms have persisted despite dietary changes.

Firstly, let’s break down your symptoms:
1. Mucus in Stool: The presence of mucus in the stool can be a normal finding, especially if you are consuming a high-fiber diet rich in fruits and vegetables. However, excessive mucus can also indicate inflammation in the intestines, which could be due to conditions such as irritable bowel syndrome (IBS), infections, or inflammatory bowel disease (IBD) like Crohn's disease or ulcerative colitis.

2. Blood in Stool: Blood in the stool can arise from various sources. The explanation provided by your doctor regarding anal trauma from wiping too hard is plausible, especially if the blood is bright red and appears on the surface of the stool. However, if the blood is mixed with the stool or if it appears darker, it could indicate bleeding from higher up in the gastrointestinal tract, such as from the colon or even the small intestine. Given your history of duodenal ulcers, it is essential to consider that these ulcers could potentially contribute to gastrointestinal bleeding.

3. Abdominal Pain: Abdominal pain can stem from numerous causes, including dietary factors, gastrointestinal motility issues, or inflammation. The suggestion that your intestines may be too dry due to a lack of fats is worth considering, as a balanced diet is crucial for maintaining healthy bowel movements.

Given that your symptoms have not improved after a week of dietary changes, it would be prudent to pursue further investigation. A colonoscopy is a valuable diagnostic tool that allows for direct visualization of the colon and rectum, and it can help identify any underlying issues such as polyps, inflammation, or other abnormalities. Since you have a history of duodenal ulcers, it is also important to rule out any complications that may arise from that condition.

In addition to a colonoscopy, you may want to consider the following steps:
- Keep a Symptom Diary: Document your symptoms, dietary intake, and any other relevant factors. This information can be helpful for your healthcare provider in determining the next steps.

- Consult a Gastroenterologist: If you haven't already, seeking a second opinion from a gastroenterologist may provide you with additional insights and recommendations tailored to your specific situation.

- Dietary Adjustments: While your doctor has suggested that dietary changes may help, it might be beneficial to work with a dietitian who specializes in gastrointestinal health. They can help you identify any potential food intolerances or sensitivities and ensure you are consuming a balanced diet that supports gut health.

- Follow-Up Testing: If symptoms persist, further testing such as stool studies, imaging studies, or even blood tests may be warranted to assess for infections, inflammation, or other gastrointestinal disorders.

In conclusion, while your doctor has provided some reasonable explanations for your symptoms, the persistence of your abdominal pain and mucus in your stool warrants further investigation. A colonoscopy could be a critical next step in identifying any underlying issues, especially given your history of duodenal ulcers. It is essential to advocate for your health and ensure that you receive the appropriate care to address your symptoms effectively.
