Mucus and Blood in Stool: Possible Causes and Solutions - Surgery

The stool consists only of some mucus and blood?


Hello Doctor, I have been experiencing this issue for a week.
The symptoms include persistent urges to have a bowel movement, but when I go to the toilet, I only pass gas and some mucus mixed with blood.
After about 10 minutes, I feel the urge to go again, and this continues throughout the day.
I can hold it in, and I wake up intermittently at night, but I do not have abdominal pain or diarrhea.
The symptoms consist of wanting to have a bowel movement but being unable to, only producing mucus with blood.
I visited an internal medicine clinic, and the doctor prescribed me antibiotics for three days, suggesting it might be an infection.
He also asked me to return for a follow-up after taking a stool test for blood.
During the follow-up, he didn't say much and prescribed me another nine days of antibiotics.
When I returned for another visit, he mentioned that if the situation persists, it could be a hemorrhoid issue.
I would like to ask what condition this might be.
Thank you, Doctor.

Based on your description, it seems more like irritable bowel syndrome combined with mild hemorrhoidal bleeding.
It is recommended to start with a light diet and maintain a good lifestyle routine.
Spicy, irritating, and greasy foods should be avoided.
If symptoms persist without improvement, you may consult a physician for medication; however, antibiotics should not be used long-term.
It is advisable to see a gastroenterologist or a colorectal specialist.
If there is still no improvement or if you are very concerned, a colonoscopy can be arranged.

The symptoms you are experiencing—persistent urges to defecate accompanied by mucus and blood in your stool—can be concerning and may indicate several underlying issues. Given your situation, it is essential to consider a few potential causes and their implications.

1. Infectious Colitis: The initial treatment with antibiotics suggests that your doctor suspected an infection. Infectious colitis can be caused by bacteria, viruses, or parasites, leading to inflammation of the colon. Symptoms often include diarrhea, abdominal pain, and sometimes blood or mucus in the stool. If the antibiotics did not resolve your symptoms, it may be worth considering further testing to identify the specific pathogen involved.

2. Inflammatory Bowel Disease (IBD): Conditions like Crohn's disease or ulcerative colitis can cause similar symptoms. These diseases are characterized by chronic inflammation of the gastrointestinal tract, leading to symptoms such as abdominal pain, diarrhea (which may be bloody), and mucus in the stool. If your symptoms persist, it may be prudent to undergo further diagnostic tests, such as a colonoscopy, to evaluate the condition of your intestines.

3. Hemorrhoids: Your doctor mentioned the possibility of hemorrhoids, which are swollen veins in the lower rectum and anus. They can cause bleeding during bowel movements, often presenting as bright red blood on the toilet paper or in the stool. While hemorrhoids are a common cause of rectal bleeding, they typically do not cause mucus production unless there is significant straining or irritation.

4. Anal Fissures: These are small tears in the lining of the anus, often caused by passing hard stools. They can lead to pain and bleeding during bowel movements. If you are experiencing straining or discomfort, this could be a contributing factor.

5. Dietary Factors: Sometimes, dietary choices can lead to changes in bowel habits and the presence of mucus or blood. A diet low in fiber can lead to constipation and straining, which may exacerbate hemorrhoids or fissures. Ensuring adequate hydration and fiber intake can help alleviate some of these symptoms.

6. Other Considerations: Less commonly, conditions such as colorectal polyps or cancer can present with similar symptoms, especially in older adults or those with a family history of gastrointestinal diseases. If your symptoms persist despite treatment, it is crucial to follow up with your healthcare provider for further evaluation.

In terms of management, it is essential to follow your doctor's recommendations closely. If you have been prescribed antibiotics, complete the course as directed. Additionally, consider discussing the following with your healthcare provider:
- Dietary Modifications: Increasing fiber intake through fruits, vegetables, and whole grains can help regulate bowel movements and reduce straining.

- Hydration: Ensure you are drinking enough fluids to help soften stools.

- Follow-Up Testing: If symptoms persist, ask about further diagnostic tests, such as a colonoscopy, to rule out more serious conditions.

In conclusion, while your symptoms may stem from relatively common issues such as infections, hemorrhoids, or dietary factors, it is crucial to monitor your condition closely. If you experience worsening symptoms, such as increased bleeding, severe pain, or changes in bowel habits, seek medical attention promptly. Your health is paramount, and addressing these symptoms early can lead to better outcomes.
