Rectal bleeding
Today, on June 25th, after lunch, I experienced significant rectal bleeding while having a bowel movement.
There is a sharp pain near the anus.
I have been staying up late frequently due to exams, and initially, there was no blood when I passed stool, but shortly after, it started dripping blood.
When I wiped, the toilet paper was completely stained with blood, with no trace of stool color.
Could this be hemorrhoids, an anal fissure, or something more serious like colorectal cancer?

Although the probability of developing colorectal cancer at the age of 20 is not zero, it is generally very low.
Based on your description, it seems likely that you are experiencing an anal fissure.
The typical symptoms include 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.
Topical ointments and suppositories can also be used for treatment.
If symptoms persist for more than a week without improvement, you should consult a physician to identify the underlying issue.

Experiencing rectal bleeding can be alarming, and it’s essential to understand the potential causes and the necessary steps to take. Based on your description, it sounds like you are dealing with a significant amount of blood during bowel movements, accompanied by pain near the anus. This situation raises concerns about several possible conditions, including hemorrhoids, anal fissures, or, in rare cases, colorectal cancer.
Hemorrhoids are swollen veins in the lower rectum or anus that can cause bleeding during bowel movements. The blood is typically bright red and may be seen on the toilet paper or in the toilet bowl. Hemorrhoids can be caused by various factors, including straining during bowel movements, prolonged sitting, or increased pressure due to pregnancy or obesity. They are generally not serious but can be uncomfortable and may require treatment.
Anal fissures are small tears in the lining of the anus, often resulting from passing hard stools or straining. They can cause sharp pain during and after bowel movements, and like hemorrhoids, they can lead to bright red blood on the toilet paper or in the toilet. Fissures can be quite painful but usually heal with proper care, including dietary changes to soften stools and topical treatments.
On the other hand, colorectal cancer is a more serious condition that can also cause rectal bleeding. However, it is important to note that the likelihood of colorectal cancer is significantly lower in younger individuals, especially if there are no other concerning symptoms such as unexplained weight loss, changes in bowel habits, or persistent abdominal pain. Given your age and the description of your symptoms, it is more likely that you are experiencing hemorrhoids or an anal fissure rather than cancer.
In your case, the fact that you have been under stress and possibly not maintaining a healthy diet could contribute to constipation or hard stools, leading to straining and subsequent bleeding. It’s also worth noting that if you have a family history of colorectal cancer, this may increase your risk, but it does not mean that you will develop it.
What should you do next? It is crucial to consult a healthcare professional for a thorough evaluation. They may recommend a physical examination and possibly a rectal examination to determine the source of the bleeding. Depending on the findings, they might suggest treatments such as dietary changes to increase fiber intake, topical medications for hemorrhoids or fissures, or further investigations like a colonoscopy if there are any concerns about more serious conditions.
In the meantime, focus on maintaining a high-fiber diet, staying hydrated, and avoiding straining during bowel movements. Foods rich in fiber include fruits, vegetables, whole grains, and legumes. If you experience persistent bleeding, severe pain, or any other concerning symptoms, seek medical attention promptly.
In summary, while rectal bleeding can stem from various causes, the most common ones are hemorrhoids and anal fissures, especially in the context of stress and dietary habits. However, due to the potential seriousness of any rectal bleeding, it is always best to err on the side of caution and consult with a healthcare provider for an accurate diagnosis and appropriate management.
