Blood with Gas: Rectal Bleeding and Hemorrhoids - Gastroenterology and Hepatology

Passing gas with fresh blood?


I was diagnosed with hemorrhoids in the third year of junior high school.
Two weeks ago, I experienced fresh blood when passing gas and sought medical attention the next day.
The doctor only asked if I had a habit of eating spicy food, drinking alcohol, or consuming sweets, and I informed him of my history of hemorrhoids.
The doctor then prescribed medication.
However, I have not reduced my intake of spicy food or alcohol.
Just now, after having a bowel movement, I noticed blood when wiping, but it took two wipes to get clean.
I'm unsure if this is an issue with my colon or rectum, or if my hemorrhoids have recurred.

Rectal bleeding, especially in the context of a known history of hemorrhoids, can be concerning and warrants careful evaluation. Hemorrhoids, which are swollen veins in the rectal area, can cause bleeding, particularly during bowel movements. The blood is often bright red, indicating that it is fresh and likely originates from the lower gastrointestinal tract. However, it is essential to differentiate between bleeding due to hemorrhoids and other potential causes, such as anal fissures, diverticular disease, or even more serious conditions like colorectal cancer.

Given your history of hemorrhoids and the recent episodes of bleeding, it is quite possible that the bleeding is related to your hemorrhoid condition. Factors such as straining during bowel movements, a low-fiber diet, and habits like consuming spicy foods and alcohol can exacerbate hemorrhoids and lead to bleeding. If you have not modified these habits, it may contribute to the recurrence of your symptoms.

However, the presence of blood in the stool or during wiping should not be taken lightly. It is crucial to consider the following:
1. Severity and Frequency of Bleeding: If the bleeding is persistent, increasing in volume, or associated with other symptoms such as pain, changes in bowel habits, or weight loss, it is essential to seek medical attention promptly.

2. Potential for Other Conditions: While hemorrhoids are a common cause of rectal bleeding, other conditions can also lead to similar symptoms. Conditions such as anal fissures, inflammatory bowel disease (IBD), or even colorectal polyps and cancer can present with rectal bleeding. Given your age and symptoms, it is advisable to have a thorough evaluation.

3. Medical Evaluation: A healthcare provider may recommend a physical examination, including a digital rectal exam, and possibly a colonoscopy to visualize the rectal and colonic mucosa. This is particularly important if you have a family history of colorectal cancer or if you are experiencing significant changes in your bowel habits.

4. Management of Hemorrhoids: If hemorrhoids are confirmed as the cause of bleeding, treatment options may include lifestyle modifications (increasing dietary fiber, hydration, and avoiding straining), topical treatments, and in some cases, procedures to remove or reduce hemorrhoids.

5. Follow-up Care: Regular follow-up with your healthcare provider is essential to monitor your condition and adjust treatment as necessary. If you notice any new symptoms or changes, do not hesitate to reach out to your doctor.

In summary, while your symptoms may be related to your known hemorrhoid condition, it is crucial to rule out other potential causes of rectal bleeding. A thorough evaluation by a healthcare professional is recommended to ensure appropriate diagnosis and treatment. Taking proactive steps in managing your diet and bowel habits can also help alleviate symptoms and prevent recurrence.
