Rectal bleeding


Hello, doctor.
I would like to ask you about some recent issues.
I've been experiencing rectal bleeding, and the amount of blood is quite significant.
I visited a clinic not long ago, and the doctor prescribed me a stool softener, which I took as directed.
However, during a bowel movement the day before yesterday, I noticed blood again, and the bleeding seems to be increasing.
The process of having a bowel movement is completely painless, so why am I bleeding? Is this serious enough to require surgery, or can it be treated with medication and topical ointments? Should I visit the clinic again for a doctor's evaluation?

It is possible to have conditions such as anal fissures, hemorrhoids, and diseases around the rectum.
You can consult a gastroenterologist or a colorectal surgeon nearby.
Dietary restrictions for rectal bleeding include avoiding spicy foods and alcohol, maintaining a regular sleep schedule, and minimizing prolonged sitting.
It is advisable to consume more vegetables and drink plenty of water.

Rectal bleeding can be a concerning symptom, and it’s important to understand when to seek medical attention. Based on your description, you are experiencing significant rectal bleeding without pain during bowel movements, which raises several considerations.

First, it’s essential to identify the potential causes of rectal bleeding. Common causes include hemorrhoids, anal fissures, diverticular disease, inflammatory bowel disease (IBD), and colorectal polyps or cancer. Hemorrhoids and anal fissures are often associated with pain, but it is possible to have bleeding without significant discomfort, especially if the bleeding is from a higher source in the gastrointestinal tract.

Given that you have already been prescribed a stool softener and are experiencing increased bleeding, it is crucial to take this seriously. Here are some guidelines on when to seek medical attention:
1. Volume of Blood: If you notice a significant amount of blood, especially if it is bright red and appears to be more than just a few drops, you should seek medical attention promptly. Large volumes of blood can indicate a more serious condition.

2. Duration and Frequency: If the bleeding persists or recurs frequently, it is advisable to consult a healthcare provider. Continuous or recurrent bleeding warrants further investigation.

3. Associated Symptoms: While you mentioned that there is no pain, it is important to be aware of other symptoms such as dizziness, weakness, or changes in bowel habits. If you experience any of these, it is essential to seek medical care immediately.

4. Previous Medical History: If you have a history of gastrointestinal issues, such as inflammatory bowel disease or polyps, or if you have a family history of colorectal cancer, it is particularly important to have any new bleeding evaluated.

5. Response to Treatment: Since you have been taking stool softeners and still experience bleeding, this may indicate that the underlying issue has not been resolved. It is advisable to follow up with your healthcare provider to reassess your condition.

In terms of management, if the bleeding is due to hemorrhoids or anal fissures, conservative treatments such as topical medications, warm baths, and dietary changes (increasing fiber intake) may be beneficial. However, if the bleeding is due to more serious conditions, further diagnostic procedures such as a colonoscopy may be necessary to identify the source of the bleeding and determine the appropriate treatment.

In conclusion, while some causes of rectal bleeding can be benign, the fact that you are experiencing significant blood loss and have not found relief with treatment suggests that you should seek medical attention. It is better to err on the side of caution when it comes to rectal bleeding, especially if the volume is increasing. A healthcare provider can perform the necessary evaluations to determine the cause of your symptoms and recommend the best course of action.
