Hemorrhoids: When to Worry About Blood in Stool - Surgery

Bowel movement issues


Hello, I have had external hemorrhoids since childhood.
Previously, I noticed bright red blood in the toilet bowl after bowel movements, but the stool itself was normal in color (yellow-brown and tubular).
The toilet paper also had bright red blood.
I consulted a general practitioner, and after examination, they confirmed that there were no internal hemorrhoids.
Recently, I have experienced the same issue again, with bright red blood on the toilet paper.
Is this still caused by hemorrhoids? Should I get checked for colorectal cancer? I occasionally experience constipation and notice a little blood, and I apply petroleum jelly to the hemorrhoids.
I also feel a tearing sensation when straining during bowel movements...

Hello! Please visit the colorectal surgery or general surgery outpatient clinic for an anoscopy.
If you continue to experience intermittent rectal bleeding, it is advisable to undergo a colonoscopy, as the incidence of colorectal cancer is decreasing in younger age groups.
Having a colonoscopy is a safer option! If the examination shows no signs of colorectal cancer, then we can address the hemorrhoids.
Changhua Hospital cares about you!

More Info


Hemorrhoids, commonly known as piles, are swollen veins in the lower rectum and anus that can cause discomfort, itching, and bleeding. It is not uncommon for individuals with a history of hemorrhoids to experience bright red blood on toilet paper or in the toilet bowl after a bowel movement. This is often due to the irritation and inflammation of the hemorrhoids, especially during straining or constipation.
In your case, since you have a history of external hemorrhoids and have previously experienced similar symptoms, it is likely that the fresh blood you are seeing is indeed related to your hemorrhoids. The bright red color of the blood typically indicates that it is coming from a source close to the anus, such as hemorrhoids or anal fissures, rather than from higher up in the gastrointestinal tract, where the blood would appear darker.

However, it is important to note that while hemorrhoids are a common cause of rectal bleeding, any new or recurrent bleeding should be taken seriously. This is particularly true if you notice changes in your bowel habits, experience significant pain, or if the bleeding persists. Although the likelihood of your symptoms being caused by something more serious, such as colorectal cancer, is relatively low given your history, it is essential to rule out any other potential causes.

Colorectal cancer can present with symptoms such as blood in the stool, changes in bowel habits (like persistent diarrhea or constipation), unexplained weight loss, and abdominal discomfort. Therefore, if you are experiencing recurrent bleeding, especially if it is accompanied by any of these other symptoms, it would be prudent to consult a healthcare professional for further evaluation.

A thorough examination may include a digital rectal exam, a colonoscopy, or other imaging studies to assess the condition of your colon and rectum. These procedures can help identify any abnormalities, including the presence of polyps, tumors, or other issues that may require treatment.

In the meantime, managing your hemorrhoids through lifestyle changes can be beneficial. This includes increasing your fiber intake to prevent constipation, staying hydrated, and avoiding straining during bowel movements. Over-the-counter treatments, such as topical creams or suppositories, can also provide relief from symptoms.

If you are experiencing significant discomfort or if the bleeding does not resolve, it is advisable to seek medical attention. A healthcare provider can offer guidance on the best course of action, which may include further diagnostic testing or treatment options tailored to your specific situation.

In summary, while your symptoms may likely be related to your existing hemorrhoids, it is essential to remain vigilant and consult a healthcare professional if the bleeding continues or if you have any concerns about your health. Early detection and intervention are key in managing any potential issues effectively.
