Rectal bleeding


Hello, doctor.
I am a working professional who often sits in front of a computer.
I usually have a bowel movement every morning, occasionally twice a day, or sometimes not at all, but at least once every two days.
However, in the past two weeks, I have noticed fresh blood on the toilet paper after wiping and also in the toilet bowl.
Additionally, I have some pain in my rectal area.
I am concerned about colorectal cancer, which has become a common issue in recent years, and I am unsure if this could be hemorrhoids.

This situation likely indicates a higher possibility of hemorrhoidal bleeding.
As long as there is no further bleeding, it should not be a concern.
It is recommended to avoid constipation during this period and to shorten the time spent on bowel movements.
Increasing dietary fiber intake can also be beneficial.
Warm sitz baths may help alleviate symptoms, and over-the-counter hemorrhoidal suppositories can be used.
However, it is best not to take stool softeners indiscriminately.
If bleeding persists, it is advisable to consult a physician for evaluation.
If necessary, a colonoscopy can also be arranged.

Blood in the stool can be a concerning symptom and may arise from various causes, some of which are benign while others can be serious. Given your description of fresh blood on toilet paper and in the toilet bowl, along with some pain in the anal area, it is essential to consider a few potential causes.

1. Hemorrhoids: One of the most common causes of bright red blood in the stool is hemorrhoids. These are swollen veins in the lower rectum or anus that can cause bleeding, especially during bowel movements. They can be internal or external, and while they can be uncomfortable, they are generally not serious.

2. Anal Fissures: Another common cause of blood in the stool is an anal fissure, which is a small tear in the lining of the anus. This can occur due to passing hard stools or straining during bowel movements. Anal fissures can cause sharp pain and bleeding, particularly during and after bowel movements.

3. Diverticular Disease: Diverticulosis, which involves the formation of small pouches in the colon wall, can lead to diverticulitis if these pouches become inflamed or infected. This condition can also cause bleeding.

4. Colorectal Polyps or Cancer: While less common, especially in younger individuals, polyps in the colon can bleed. Some polyps can be precursors to colorectal cancer. Given the increasing incidence of colorectal cancer in younger populations, it is essential to take any rectal bleeding seriously.

5. Gastrointestinal Infections: Certain infections can lead to inflammation and bleeding in the gastrointestinal tract, resulting in blood in the stool.

6. Other Causes: Conditions such as inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis, can also lead to rectal bleeding.


When to Seek Help
You should seek medical attention promptly if you experience any of the following:
- Persistent Bleeding: If the bleeding continues or worsens.

- Severe Pain: If you have significant pain that does not improve.

- Changes in Bowel Habits: If you notice a change in your bowel habits, such as diarrhea or constipation lasting more than a few days.

- Other Symptoms: If you experience symptoms such as dizziness, fainting, or significant abdominal pain, which could indicate a more serious condition.


Diagnostic Steps
When you visit a healthcare provider, they may perform several diagnostic tests, including:
- Physical Examination: A thorough examination, including a digital rectal exam, to check for hemorrhoids or fissures.

- Colonoscopy: This procedure allows the doctor to view the inside of your colon and rectum, helping to identify any polyps, tumors, or sources of bleeding.

- Blood Tests: To check for anemia or other underlying conditions.


Conclusion
While hemorrhoids and anal fissures are common and often benign causes of blood in the stool, it is crucial not to dismiss this symptom, especially given the potential for more serious conditions like colorectal cancer. Given your work situation and lifestyle, it may also be beneficial to evaluate your diet and hydration, as a fiber-rich diet can help prevent constipation and reduce the risk of hemorrhoids and fissures.
In summary, it is advisable to consult a healthcare professional for a thorough evaluation and appropriate management. Early diagnosis and treatment are key to addressing any underlying issues effectively.
