Blood in Stool: Symptoms and When to See a Doctor

Rectal bleeding

Yesterday, after having a bowel movement, I noticed that the toilet water turned bright red, and there was blood when I wiped, but it stopped after a few wipes.
The stool was somewhat hard, but the color was obscured by the blood, making it hard to see.
Today at noon, during another bowel movement, the stool was shaped like a log and dark brown, but the latter part of the stool was a bit loose and had a little blood as well.
The log-shaped stool had some blood attached to it.
Doctor, what could be the cause of this situation? Is it possible that this is a sign of rectal cancer or colon cancer? Should I see a doctor, or is it unnecessary since I'm not actively bleeding?

At the age of 22, the likelihood of developing colorectal cancer is not zero, but it is generally very low.
In this case, the possibility of hemorrhoidal bleeding is much higher.
As long as there is no further bleeding, there is no need for concern.
It is recommended to avoid constipation during this period and to shorten the time spent on bowel movements.
Increasing dietary fiber intake can also be beneficial.
Warm sitz baths may help alleviate symptoms, and over-the-counter hemorrhoid suppositories can be used.
It is best to avoid taking laxatives indiscriminately.
If bleeding persists, it is advisable to consult a physician for evaluation.

More Info

When you notice blood in your stool, it can understandably cause concern, especially regarding serious conditions like colorectal cancer. However, it's important to remember that there are various potential causes for this symptom, and not all of them are severe.
The bright red blood you observed in the toilet water and on toilet paper typically indicates that the bleeding is coming from the lower gastrointestinal tract, such as the rectum or anus. This could be due to several reasons, including hemorrhoids, anal fissures, diverticular disease, or even infections. Hemorrhoids, which are swollen veins in the rectal area, are a common cause of bright red blood during bowel movements. Anal fissures, which are small tears in the lining of the anus, can also lead to bleeding, especially if the stool is hard and difficult to pass.

The fact that you mentioned the blood was present only occasionally and that your stool was somewhat hard suggests that constipation might be a contributing factor. Hard stools can cause straining during bowel movements, leading to fissures or exacerbating hemorrhoids.
On the other hand, if the blood is mixed with the stool or if you experience other symptoms such as significant abdominal pain, changes in bowel habits, unexplained weight loss, or persistent changes in the color or consistency of your stool, it could indicate a more serious condition, including colorectal cancer.
Colorectal cancer often presents with symptoms such as:
1. Blood in the stool (which can be bright red or dark).

2. A change in bowel habits, such as diarrhea or constipation that lasts longer than a few days.

3. Unexplained weight loss.

4. Abdominal discomfort or pain.

5. A feeling that your bowel doesn’t empty completely.

Given your symptoms, it is advisable to consult a healthcare professional. While it may not be an emergency, a medical evaluation is important to rule out any serious conditions. A doctor may recommend a physical examination, a digital rectal exam, and possibly a colonoscopy to investigate the source of the bleeding.
In the meantime, you can take steps to alleviate constipation, such as increasing your fiber intake through fruits, vegetables, and whole grains, staying hydrated, and engaging in regular physical activity. Over-the-counter stool softeners or laxatives may also help if you are experiencing hard stools.

In summary, while the presence of blood in your stool can be alarming, it does not always indicate a severe condition. However, given the potential seriousness of gastrointestinal bleeding, it is wise to seek medical advice to ensure proper diagnosis and treatment. Remember, early detection and intervention are key in managing any health issues effectively.
