Blood in stool, anal fissure, hemorrhoids?


Hello Doctor: My usual bowel habit is once a day or once every two days, but I didn't have a bowel movement yesterday.
Today, when I wiped after having a bowel movement, I noticed bright red blood, but it was gone after wiping again.
This situation occurs occasionally, but I don't feel any pain in my anus, just a slight warm sensation.
Could this be anal fissure or hemorrhoids? Do I need to see a gastroenterologist? Thank you.

Hello, ma'am.
Painless bleeding is often associated with internal hemorrhoids.
It's common for healthy individuals to experience some bleeding from internal hemorrhoids, especially during constipation.
Therefore, you can monitor the situation.
If the bleeding persists, you should schedule an appointment with a gastroenterologist.
Changhua Hospital cares about your health.

More Info


When it comes to the presence of blood in the stool, it can be concerning and may indicate various underlying conditions. In your case, the observation of bright red blood on the toilet paper after wiping, especially without accompanying pain, could suggest a few possibilities, primarily anal fissures or hemorrhoids.

Anal Fissures: These are small tears in the lining of the anus, often caused by passing hard stools or straining during bowel movements. They can lead to bleeding, which is typically bright red and may be seen on the toilet paper or in the toilet bowl. While fissures can be painful, some individuals may not experience significant pain, especially if the fissure is not acute or if the bowel movement was not particularly difficult.

Hemorrhoids: These are swollen veins in the lower rectum or anus that can cause bleeding during bowel movements. The blood from hemorrhoids is also usually bright red and can appear on the toilet paper or in the stool. Hemorrhoids can be internal or external, and while they can cause discomfort, they do not always lead to pain, especially if they are not thrombosed (clotted).

Given that you mentioned a sensation of heat but no significant pain, it leans slightly more towards hemorrhoids, but fissures cannot be ruled out without further examination. The intermittent nature of your symptoms, along with the absence of pain, suggests that it might not be a severe condition, but it is still essential to monitor the situation.

When to Seek Medical Attention: It is advisable to consult a gastroenterologist if:
1. The bleeding persists or worsens.

2. You experience significant pain, discomfort, or changes in bowel habits.

3. There are other symptoms such as weight loss, changes in appetite, or abdominal pain.

Self-Care and Management: In the meantime, you can take some self-care measures:
- Dietary Changes: Increase fiber intake through fruits, vegetables, and whole grains to soften stools and reduce straining.

- Hydration: Drink plenty of water to help maintain stool consistency.

- Warm Baths: Soaking in warm water can help soothe the anal area and promote healing.

- Over-the-Counter Treatments: Creams or ointments for hemorrhoids can provide relief if that is the issue.

In conclusion, while your symptoms could indicate either anal fissures or hemorrhoids, the best course of action is to monitor your symptoms and consult a healthcare professional if they persist or worsen. Early intervention can help prevent complications and ensure appropriate treatment.
