Rectal bleeding

Hello Doctor: About six months ago, I experienced rectal bleeding during bowel movements.
My stool is usually yellowish, and it seems to darken slightly after consuming chocolate or similar foods.
Sometimes the stool is formed, and other times it is not.
I do not have severe abdominal pain, anemia, dizziness, or loss of appetite.
The red blood appears to be attached to the stool, and there is a slight mucous texture.
The amount of blood is minimal, and when wiping, there is rarely any blood, and if there is, it is just a small amount.
Eventually, I noticed that this issue seemed to resolve on its own.
However, recently, after having breakfast one morning, I felt a strong urge to have a bowel movement but held it for about 10 minutes before going.
Afterward, I noticed a similar situation to what I experienced before, which has me quite worried.
I am unsure if there is an underlying issue.
My dietary habits include eating vegetables and fruits, rarely consuming meat, but I have a strong preference for bread, cookies, and snacks.
Thank you for your guidance, Doctor.

Hello, Miss: If you are experiencing intermittent blood in your stool or blood-streaked stools, rather than passing bright red blood (which is often associated with hemorrhoidal bleeding), it is recommended to undergo a flexible sigmoidoscopy (to examine the lower colon up to 60 centimeters) or a colonoscopy.
Additionally, many facilities now offer the option of self-paying for sedation during a colonoscopy, which alleviates any pain concerns.

More Info

Rectal bleeding can be a concerning symptom, and understanding its potential causes is essential for maintaining good digestive health. Based on your description, it seems that you have experienced intermittent rectal bleeding, which has not been accompanied by severe abdominal pain, dizziness, or other alarming symptoms like significant weight loss or changes in appetite. However, the presence of blood in your stool, even in small amounts, warrants a closer look.

Common Causes of Rectal Bleeding
1. Hemorrhoids: One of the most common causes of rectal bleeding, especially if the blood is bright red and appears on the surface of the stool or on toilet paper. Hemorrhoids can be internal or external and are often associated with straining during bowel movements, which can occur if you experience constipation or have infrequent bowel movements.

2. Anal Fissures: These are small tears in the lining of the anus, often caused by passing hard stools. They can lead to sharp pain during bowel movements and may cause bleeding that is bright red and noticeable on the stool or toilet paper.

3. Diverticular Disease: Diverticulosis is a condition where small pouches form in the colon wall. If these pouches become inflamed or infected (diverticulitis), they can cause bleeding.

4. Inflammatory Bowel Disease (IBD): Conditions like Crohn's disease and ulcerative colitis can lead to inflammation of the digestive tract, resulting in symptoms such as abdominal pain, diarrhea, and rectal bleeding.

5. Polyps or Colorectal Cancer: While less common, polyps (growths on the colon lining) can bleed, and some can develop into cancer. It’s important to monitor any changes in bowel habits or the appearance of blood.

Your Symptoms and Concerns
From your description, the blood appears to be bright red and is accompanied by a bit of mucus, which is consistent with hemorrhoids or anal fissures, especially if you have experienced any straining during bowel movements. The fact that you have a diet rich in fruits and vegetables is generally beneficial for digestive health, as it helps to maintain regular bowel movements and prevent constipation. However, if you are consuming a lot of processed foods like bread and snacks, this could contribute to irregular bowel habits.

Recommendations
1. Dietary Adjustments: Continue to consume a high-fiber diet, including fruits, vegetables, and whole grains, to promote regular bowel movements. Ensure you are drinking plenty of water to help soften stools.

2. Avoid Straining: If you feel the urge to go, try not to delay bowel movements. Straining can exacerbate hemorrhoids and lead to fissures.

3. Over-the-Counter Treatments: For hemorrhoids, topical treatments such as creams or ointments can provide relief. Warm sitz baths may also help soothe discomfort.

4. Monitor Symptoms: Keep track of your symptoms, including the frequency of bleeding, the amount of blood, and any associated symptoms like pain or changes in bowel habits.

5. Consult a Healthcare Provider: Given your history of rectal bleeding, it is advisable to consult a healthcare provider, especially if the bleeding persists or worsens. They may recommend a physical examination, and possibly a colonoscopy, to rule out more serious conditions.

Conclusion
While many cases of rectal bleeding are benign and related to hemorrhoids or fissures, it is crucial to take any instance of rectal bleeding seriously. Regular check-ups and open communication with your healthcare provider about your symptoms can help ensure that any potential issues are addressed promptly. Remember, early detection and intervention are key to maintaining good digestive health.
