Rectal Bleeding: Is It Hemorrhoids or Anal Fissures? - Gastroenterology and Hepatology

Anal issues


Hello doctor, a few months ago I noticed a small amount of blood when wiping after using the toilet.
At that time, I was preparing for college entrance exams, so I didn't pay much attention to it.
Since then, I've experienced this situation two or three more times, and this week there was more blood than before when I wiped, although the amount is still small and there is no blood in my stool.
Could this condition be hemorrhoids or an anal fissure? If so, can it heal on its own?

Hello: If you experience blood in your stool without pain in the anus, it is often indicative of internal hemorrhoid bleeding.
However, it is advisable to visit a gastroenterology clinic for a check-up.

Rectal bleeding can be concerning, and it's important to understand the potential causes and implications. Based on your description, the presence of blood when wiping after a bowel movement could indeed be indicative of either hemorrhoids or anal fissures, both of which are common conditions.

Hemorrhoids are swollen veins in the lower rectum or anus. They can be internal or external. Internal hemorrhoids are usually not visible and may cause bleeding during bowel movements, which is often bright red. External hemorrhoids can be painful and may cause discomfort, especially if a blood clot forms. Symptoms can include itching, discomfort, and bleeding.

Anal fissures, on the other hand, are small tears in the lining of the anus, often caused by passing hard stools or straining during bowel movements. They can lead to sharp pain during and after bowel movements, and may also cause bleeding, typically bright red in color. The pain associated with fissures can be quite severe, and they may take longer to heal if not managed properly.

Given that you have experienced this bleeding multiple times, it is advisable to consider a few factors:
1. Symptoms: If you are experiencing pain during bowel movements, it may lean more towards an anal fissure. If there is no pain but only bleeding, hemorrhoids might be more likely.

2. Stool Consistency: Hard stools can exacerbate both conditions. Ensuring a diet high in fiber, staying hydrated, and possibly using stool softeners can help prevent further irritation.

3. Self-Care: Both conditions can often improve with conservative management. This includes dietary changes, warm baths (sitz baths), and over-the-counter topical treatments for hemorrhoids. For fissures, applying topical anesthetics or healing ointments may provide relief.

4. Healing Time: Many mild cases of hemorrhoids and anal fissures can heal on their own with proper care. However, if symptoms persist for more than a week or worsen, it is crucial to seek medical attention.

5. Medical Evaluation: While self-care is often effective, a healthcare provider can offer a definitive diagnosis through a physical examination. They may also perform a digital rectal exam or anoscopy if necessary. This is important to rule out other potential causes of rectal bleeding, such as polyps or more serious conditions.

In summary, while it is possible that your symptoms are due to hemorrhoids or anal fissures, a proper evaluation by a healthcare professional is essential to confirm the diagnosis and rule out other potential issues. If you notice any significant changes in your symptoms, such as increased bleeding, pain, or changes in bowel habits, do not hesitate to seek medical advice. Early intervention can lead to better outcomes and prevent complications.
