Blood in Stool: When to See a Doctor for Concerns - Gastroenterology and Hepatology

Blood in stool

Hello, doctor.
I have regular bowel movements every 2 to 3 days.
Recently, I've noticed a small amount of bright red blood at the end of my stool on the 6th, 1st, and 3rd days.
For example, this afternoon I had a bowel movement without blood, but just now in the evening, there was blood at the end.
I read online that this might be hemorrhoids.
Under what circumstances should I see a doctor? Should I see a doctor every time I have blood in my stool?

Dr. Lin Minghui reply Gastroenterology and Hepatology

Hello,
For a 40-year-old male with rectal bleeding, differential diagnoses include hemorrhoids, anal fissures, polyps, colitis, and colorectal cancer.
It is recommended to follow up with a colorectal or gastroenterology clinic to confirm whether the diagnosis is hemorrhoids.
Prolonged bleeding can lead to anemia, and in severe cases, may cause palpitations and shortness of breath, which should not be taken lightly.
It is advisable to consume more vegetables and maintain adequate hydration to ensure smooth bowel movements.

Wishing you safety and health,
Dr.

More Info

When it comes to the presence of blood in stool, it is essential to approach the situation with caution and awareness of the potential underlying causes. The fact that you have noticed bright red blood at the end of your stool can indeed suggest a few possibilities, with hemorrhoids (or piles) being one of the most common causes. Hemorrhoids are swollen veins in the lower rectum or anus that can cause discomfort, itching, and bleeding, especially during bowel movements.

However, while hemorrhoids are a frequent cause of rectal bleeding, it is crucial to consider other potential causes as well. These can include anal fissures, diverticular disease, colorectal polyps, or even more serious conditions such as colorectal cancer. The key is to monitor the situation closely and understand when it is appropriate to seek medical advice.

Here are some guidelines on when to see a doctor regarding blood in your stool:
1. Persistent Bleeding: If you notice blood in your stool consistently over a few days or weeks, it is advisable to consult a healthcare professional. Even if the blood is bright red and seems to be associated with hemorrhoids, persistent bleeding should not be ignored.

2. Volume of Blood: If you experience a significant amount of blood, or if the bleeding is accompanied by other symptoms such as dizziness, weakness, or fainting, you should seek immediate medical attention. This could indicate a more serious condition that requires urgent care.

3. Accompanying Symptoms: If the bleeding is accompanied by other concerning symptoms such as abdominal pain, changes in bowel habits (like diarrhea or constipation), unexplained weight loss, or changes in appetite, it is essential to see a doctor. These symptoms could indicate a more serious underlying condition.

4. Age and Risk Factors: If you are over the age of 50, or if you have a family history of colorectal cancer or other gastrointestinal diseases, it is prudent to be more vigilant about any signs of bleeding and to consult a healthcare provider sooner rather than later.

5. Duration: If the bleeding lasts more than a few days, even if it seems minor, it is wise to seek medical advice. A healthcare professional can perform the necessary examinations, such as a digital rectal exam or a colonoscopy, to determine the cause of the bleeding.

In summary, while bright red blood in the stool can often be attributed to benign conditions like hemorrhoids, it is essential to remain vigilant and consult a healthcare provider if the bleeding persists, increases in volume, or is accompanied by other concerning symptoms. Early evaluation and diagnosis can help rule out serious conditions and ensure appropriate treatment. Always prioritize your health and do not hesitate to seek medical advice when in doubt.
