Blood in the stool?


Hello Doctor: I do not have issues with constipation and have regular bowel movements every day.
I previously experienced issues with hemorrhoids, but that was quite some time ago.
However, in the past two days, I have noticed that my stool has been somewhat hard, and there is a bit of pain at the anal opening.
This morning, after having a bowel movement, I checked the shape and color of my stool as usual.
The first 3-5 centimeters of the stool that came out was very dry, resembling Type 3 on the Bristol Stool Chart: a sausage shape with cracks on the surface.
The middle part of the stool was smooth and not dry, while the end became soft and lumpy.
I noticed that there were some slight red streaks of blood on the smooth part of the stool in the middle.
When I picked it up with chopsticks, it was indeed blood.
Could you please advise if this bleeding is caused by the hard stool at the front causing friction, or could it be due to another condition?

Hello Mr.
Ayou: If there is a phenomenon of rectal bleeding with bowel movements, it is recommended to schedule a colonoscopy in the outpatient department to rule out certain conditions.
Thank you for your inquiry.

The presence of blood in the stool can be a concerning symptom and is often indicative of various gastrointestinal issues. Based on your description, it seems you are experiencing a combination of hard stools and the presence of blood, which can be alarming. Let's break down the potential causes and concerns associated with your symptoms.

Firstly, the type of blood you are observing is crucial in determining the underlying issue. If the blood is bright red and appears on the surface of the stool or is mixed with it, this typically suggests that the source of bleeding is in the lower gastrointestinal tract, such as the rectum or anus. Common causes of this type of bleeding include hemorrhoids, anal fissures, or even diverticular disease. Given your history of hemorrhoids, it is possible that the hard stools are causing irritation or tearing in the anal area, leading to the blood you are seeing.

The Bristol Stool Chart, which you referenced, categorizes stool types based on their shape and consistency. Type 3, which you described as having a long, sausage-like shape with cracks on the surface, indicates that your stool is somewhat hard but not severely constipated. However, the presence of hard stools can lead to straining during bowel movements, which can exacerbate issues like hemorrhoids or cause anal fissures, both of which can result in bleeding.

In your case, it is likely that the blood you are seeing is due to the hard stool causing friction and irritation as it passes through the anal canal. This is a common scenario, especially if you have been experiencing any changes in your diet or hydration levels. Dehydration or a low-fiber diet can contribute to harder stools, making them more difficult to pass and increasing the risk of bleeding.

However, while hemorrhoids and anal fissures are common and often benign causes of rectal bleeding, it is essential to remain vigilant. If the bleeding persists, increases in volume, or is accompanied by other symptoms such as significant abdominal pain, changes in bowel habits, or weight loss, it would be prudent to seek medical attention. A healthcare provider may recommend a physical examination and possibly a colonoscopy to rule out more serious conditions, such as colorectal polyps or cancer, especially if you have a family history of gastrointestinal diseases.

In addition to monitoring your symptoms, consider making some dietary adjustments to help alleviate your current issues. Increasing your fiber intake through fruits, vegetables, and whole grains can help soften your stools and promote regular bowel movements. Staying well-hydrated is also crucial, as adequate fluid intake can prevent constipation and reduce the hardness of stools. If you find that dietary changes alone are not sufficient, over-the-counter stool softeners or fiber supplements may be beneficial.

In summary, while the blood in your stool may likely be due to hard stools causing irritation, it is essential to monitor your symptoms closely. If you experience any concerning changes or if the bleeding continues, do not hesitate to consult a healthcare professional for further evaluation and management. Your gastrointestinal health is important, and addressing these symptoms early can help prevent more significant issues down the line.
