The issue of rectal bleeding?


I previously visited the hospital due to bowel issues, experiencing pain during defecation and blood in my stool.
The doctor suggested it might be hemorrhoids or anal fissures and prescribed an ointment and a stool softener, which improved my condition.
However, in the past two days, I have experienced anal pain again due to constipation.
I applied the previous medication, which alleviated the pain somewhat, but it still persists.

I noticed an issue with the color of my stool.
Two days ago, my stool was long and abundant, mostly yellow-brown, with a slight amount of blood in the toilet water.
There were also two areas within the stool that had a reddish substance, which I am unsure if it is blood or red radishes I had for dinner the previous night.
The reddish material appeared to be embedded in the stool rather than just blood on the surface.

Yesterday, after eating a casserole with satay sauce, which I usually avoid due to my sensitivity to spicy foods, I had a softer stool today.
The anal pain felt like tearing again, and there was a slight amount of blood in the toilet water.
The surface of the stool did not show any abnormal color, but when I used the toilet brush to clean the stool, I noticed that the color on the toilet wall seemed reddish.
This alarmed me, so I checked other stool remnants, and this time the color on the toilet wall was brown, but there was a small visible red substance (approximately 0.1 cm in diameter) mixed within.
Recently, I consulted a gastroenterologist regarding my bowel issues, and the doctor suspected hemorrhoids, but I have not confirmed whether I have internal or external hemorrhoids.
I am still very concerned about the recurring blood in my stool.
My grandmother mentioned that she has experienced fresh blood during bowel movements for over 20 years, and my grandfather reportedly had instances where only blood was passed.
My family is also very resistant to undergoing examinations.
What should I do?

More Info


Understanding blood in stool can be a concerning issue, especially when it is accompanied by pain during bowel movements. Based on your description, it seems you have experienced symptoms consistent with hemorrhoids or anal fissures, which are common causes of rectal bleeding. However, the presence of blood in stool can also indicate other gastrointestinal issues, and it is essential to approach this matter with caution.


Causes of Blood in Stool
1. Hemorrhoids: Swollen veins in the lower rectum or anus can cause pain and bleeding during bowel movements. The blood is usually bright red and may appear on the toilet paper or in the toilet bowl.

2. Anal Fissures: These are small tears in the lining of the anus, often caused by passing hard stools. They can be very painful and may also result in bright red blood.

3. Diverticular Disease: Diverticula are small pouches that can form in the walls of the colon. If they become inflamed or infected, they can cause bleeding.

4. Gastrointestinal Conditions: Conditions such as inflammatory bowel disease (IBD), colorectal polyps, or even colorectal cancer can lead to blood in the stool. These conditions may present with other symptoms, such as changes in bowel habits, weight loss, or abdominal pain.

5. Dietary Factors: Certain foods, like beets or red food coloring, can sometimes mimic blood in the stool. However, if the blood is mixed within the stool rather than just on the surface, it is more concerning.


Next Steps
Given your family history of gastrointestinal issues, it is crucial to take your symptoms seriously. Here are some recommendations:
1. Consult a Gastroenterologist: Since you have already seen a gastroenterologist, it may be beneficial to return for a follow-up. Discuss your ongoing symptoms and express your concerns about the blood in your stool. A thorough examination, including a digital rectal exam or possibly a colonoscopy, may be warranted to rule out more serious conditions.

2. Keep a Symptom Diary: Document your bowel movements, including the appearance of your stool, any pain experienced, and the presence of blood. This information can be helpful for your doctor in diagnosing the issue.

3. Dietary Adjustments: Since you mentioned issues with constipation, consider increasing your fiber intake through fruits, vegetables, and whole grains. Staying hydrated is also essential. If you have dietary triggers, such as spicy foods, it may be wise to avoid them.

4. Avoid Self-Diagnosis: While it is tempting to self-diagnose based on symptoms, it is crucial to rely on professional medical advice. Your family history adds complexity to your situation, and a healthcare professional can provide a more accurate diagnosis.

5. Family History Consideration: Given that your grandmother and grandfather had similar symptoms, it is essential to discuss this family history with your doctor. Certain gastrointestinal conditions can have hereditary components, and this information can guide your doctor in determining the best course of action.

6. Addressing Anxiety: It is understandable to feel anxious about these symptoms, especially with a family history of gastrointestinal issues. Consider discussing your concerns with a mental health professional if anxiety becomes overwhelming.


Conclusion
Blood in the stool is not something to ignore, especially with your symptoms and family history. While hemorrhoids and anal fissures are common causes, it is essential to rule out more serious conditions. Follow up with your gastroenterologist, keep track of your symptoms, and make necessary dietary changes. Your health is paramount, and seeking professional guidance is the best way to ensure your well-being.
