Blood in Stool: Causes and Concerns for Constipation - Surgery

Rectal bleeding


Hello Doctor: I have had chronic constipation for a long time, but recently I noticed some blood streaks in my stool.
The amount of blood is very small, and there is also a little blood on the toilet paper, but there seems to be more blood in the stool than on the paper.
A few days ago, my stool was ribbon-like, but in the past few days, it has been more pellet-like.
I would like to know what this could possibly indicate.
Thank you!

Based on your description, it seems to be a typical symptom of anal fissure, which is characterized by pain during bowel movements accompanied by slight bleeding.
If there is concurrent bleeding from hemorrhoids, the amount of blood may be more significant.
The primary cause of anal fissures is usually hard stools, but diarrhea, frequent bowel movements, or prolonged straining can also lead to fissures.
It is advisable to improve bowel habits and to take warm sitz baths to alleviate symptoms.
Increasing dietary fiber and fluid intake is also very important.
Topical ointments and suppositories can be used for treatment.
If symptoms persist for more than a week without improvement, it is essential to consult a physician to identify the underlying issue.

More Info


When it comes to the presence of blood in stool, especially in the context of constipation, there are several potential causes and considerations that need to be addressed. The fact that you have a history of constipation is significant, as chronic constipation can lead to various complications, including the development of hemorrhoids or anal fissures, both of which can cause bleeding.


Possible Causes of Blood in Stool
1. Hemorrhoids: These are swollen veins in the lower rectum or anus that can bleed, especially during bowel movements. If your stools have been hard due to constipation, straining can exacerbate hemorrhoids, leading to blood on the stool or toilet paper.

2. Anal Fissures: These are small tears in the lining of the anus, often caused by passing hard stools. They can be quite painful and may cause bright red blood to appear on the stool or toilet paper.

3. Diverticular Disease: This condition involves the formation of small pouches in the colon wall, which can become inflamed or infected, leading to bleeding.

4. Polyps or Colorectal Cancer: While less common, especially in younger individuals, polyps can bleed and may be a sign of more serious conditions like colorectal cancer. It’s essential to consider this, especially if there are changes in bowel habits or stool consistency.

5. Gastrointestinal Infections: Certain infections can lead to inflammation and bleeding in the gastrointestinal tract, although this is often accompanied by other symptoms like diarrhea, fever, or abdominal pain.


What to Do Next
Given your symptoms, it is crucial to take the following steps:
1. Consult a Healthcare Provider: It is essential to see a doctor, preferably a gastroenterologist, who can evaluate your symptoms in detail. They may recommend a physical examination, and possibly a colonoscopy or other imaging studies to determine the source of the bleeding.

2. Monitor Symptoms: Keep track of any additional symptoms you may experience, such as changes in bowel habits, abdominal pain, weight loss, or fatigue. This information can be helpful for your healthcare provider.

3. Dietary Adjustments: To alleviate constipation, consider increasing your fiber intake through fruits, vegetables, and whole grains, and ensure you are drinking plenty of water. Sometimes, a fiber supplement may be beneficial. Regular physical activity can also help promote bowel regularity.

4. Avoid Straining: If you are experiencing constipation, try to avoid straining during bowel movements, as this can worsen hemorrhoids and fissures. If necessary, discuss with your doctor the use of stool softeners or mild laxatives.

5. Follow-Up: If the bleeding persists, worsens, or if you develop new symptoms, seek medical attention promptly.


Conclusion
While the presence of blood in the stool can be alarming, it is essential to approach the situation calmly and methodically. Many causes of rectal bleeding are benign and treatable, especially when addressed early. However, it is crucial to rule out more serious conditions through appropriate medical evaluation. Your health and well-being should always be your top priority, so do not hesitate to seek professional help.
