Rectal bleeding


Hello, doctor! Today, during bowel movement, it started off very hard, and then I felt a bit of tearing sensation.
Later, it turned into soft stools.
I didn't pay much attention to whether the bleeding was before or after the stool, but after I stood up, I noticed a large amount of bright red blood on the stool (I've never experienced this much blood before; the most I had was just a little bit on the tissue).
This time, there was also a lot of blood on the tissue, but after wiping a second time, there was none.
My anus doesn't feel extremely painful right now.
I read some information about colorectal cancer and I'm feeling quite anxious.
How long should I observe my symptoms before seeing a doctor?

At the age of 23, the likelihood of developing colorectal cancer is not zero, but it is generally very low.
Based on your description, it seems more like bleeding from hemorrhoids combined with an anal fissure.
It is recommended to maintain a light diet and a good lifestyle.
Spicy, irritating, and greasy foods should be avoided.
If symptoms persist without improvement, you should consult a physician for medication.

Rectal bleeding can be a concerning symptom, and it's understandable that you are feeling anxious about it, especially given your previous experiences and the information you've read about colorectal cancer. Let's break down the situation and discuss when you should seek medical attention.

Firstly, it's important to note that rectal bleeding can have various causes, ranging from benign to serious. Common causes include hemorrhoids, anal fissures, diverticular disease, and inflammatory bowel disease. In your case, since you mentioned experiencing a hard stool followed by a tearing sensation, it is possible that you may have developed an anal fissure, which is a small tear in the lining of the anus. This can lead to bleeding, especially if the stool is hard and difficult to pass.

The fact that you observed a significant amount of bright red blood on the stool and toilet paper can be alarming. Bright red blood typically indicates that the bleeding is coming from the lower gastrointestinal tract, such as the rectum or anus, rather than from higher up in the digestive system, where the blood would appear darker. However, the presence of blood, regardless of the amount, should always be taken seriously.

Given your symptoms, here are some guidelines on when to seek medical attention:
1. If the bleeding persists: If you continue to see blood in your stool or on toilet paper over the next few days, it is advisable to consult a healthcare professional. Persistent bleeding should not be ignored.

2. If you experience severe pain: While you mentioned that you do not have severe pain currently, if you start to experience significant discomfort or pain in the rectal area, this could indicate a more serious issue that requires immediate attention.

3. If you notice changes in your bowel habits: If you experience changes such as diarrhea, constipation, or changes in the consistency of your stool, especially if accompanied by blood, you should see a doctor.

4. If you have other concerning symptoms: Symptoms such as weight loss, fatigue, or changes in appetite, along with rectal bleeding, warrant a visit to a healthcare provider.

5. If you have a family history of colorectal cancer: If you have a family history of colorectal cancer or other gastrointestinal diseases, it is prudent to seek medical advice sooner rather than later.

In general, if you are feeling anxious about your symptoms, it is always better to err on the side of caution and consult a healthcare professional. They can perform a thorough evaluation, which may include a physical examination, a digital rectal exam, and possibly further diagnostic tests such as a colonoscopy, especially if they deem it necessary based on your symptoms and medical history.

In the meantime, to help manage your symptoms, consider increasing your fiber intake to help soften your stools and make bowel movements easier. Staying hydrated is also crucial. Over-the-counter remedies for hemorrhoids or fissures may provide some relief, but be sure to consult with a healthcare provider before starting any new treatment.

In summary, while it is possible that your symptoms may be due to a benign condition, it is essential to monitor your situation closely and seek medical attention if your symptoms persist or worsen. Your health and peace of mind are important, and a healthcare professional can provide the necessary guidance and reassurance.
