Rectal bleeding


A few days ago, I noticed blood in my stool, which seemed to occur after bowel movements.
It only lasted for a wipe or two and then stopped.
Recently, I haven't seen any more blood.
Should I not worry as long as the bleeding doesn't continue?

Blood in the stool is an abnormal phenomenon, with hemorrhoidal bleeding being the most likely cause.
However, there are many potential reasons for rectal bleeding, as the entire gastrointestinal tract can be a source of blood in the stool.
To avoid unnecessary speculation and anxiety, it is recommended that you visit a surgical or internal medicine outpatient clinic for evaluation.

More Info


Rectal bleeding can be a concerning symptom, and it's important to understand the potential causes and when to seek medical attention. Based on your description, it seems that you experienced rectal bleeding after a bowel movement, which resolved quickly. This can be indicative of several conditions, some of which are benign, while others may require more serious attention.


Common Causes of Rectal Bleeding
1. Hemorrhoids: One of the most common causes of rectal bleeding, especially if the blood is bright red and appears on the toilet paper or in the toilet bowl. Hemorrhoids can be internal or external and are often associated with straining during bowel movements, constipation, or prolonged sitting.

2. Anal Fissures: These are small tears in the lining of the anus, often caused by passing hard stools. They can cause sharp pain and bleeding during or after bowel movements.

3. Diverticular Disease: Diverticulosis can lead to diverticulitis, which may cause bleeding. This is more common in older adults.

4. Colorectal Polyps or Cancer: While less common, polyps can bleed, and colorectal cancer can present with rectal bleeding, especially in older adults or those with a family history of colorectal cancer.

5. Inflammatory Bowel Disease (IBD): Conditions like Crohn's disease or ulcerative colitis can cause rectal bleeding, often accompanied by other symptoms like diarrhea, abdominal pain, and weight loss.


When to Seek Medical Attention
While occasional minor rectal bleeding, especially from hemorrhoids or fissures, may not be a cause for alarm, there are specific situations where you should seek medical attention:
- Persistent Bleeding: If you notice blood in your stool or on toilet paper for more than a few days, it's essential to consult a healthcare provider.

- Increased Amount of Blood: If the bleeding becomes more significant or is accompanied by clots, this warrants immediate medical evaluation.

- Accompanying Symptoms: If you experience other symptoms such as severe abdominal pain, changes in bowel habits, weight loss, or fatigue, you should seek medical advice.

- Age Considerations: If you are over 50 or have a family history of colorectal cancer, any rectal bleeding should be evaluated by a doctor.


What to Do
1. Monitor Symptoms: Keep track of your symptoms, including the frequency and amount of bleeding, any associated pain, and changes in bowel habits.

2. Dietary Changes: Increasing fiber intake can help prevent constipation and reduce straining during bowel movements, which can alleviate hemorrhoids and fissures.

3. Hydration: Ensure you are drinking enough fluids to help maintain soft stools.

4. Avoid Straining: When using the bathroom, try to relax and avoid straining, which can exacerbate hemorrhoids and fissures.

5. Consult a Doctor: If symptoms persist or worsen, schedule an appointment with a healthcare provider for a thorough evaluation. They may recommend a physical examination, colonoscopy, or other diagnostic tests to determine the cause of the bleeding.

In summary, while occasional rectal bleeding may not always indicate a serious problem, it is crucial to be vigilant and seek medical advice if the bleeding persists, increases, or is accompanied by other concerning symptoms. Early diagnosis and treatment can lead to better outcomes, especially for conditions that may require intervention.
