This situation likely indicates a higher possibility of hemorrhoidal bleeding.
As long as there is no further bleeding, it should not be a 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.
Although the risk of developing colorectal cancer at the age of 18 is not zero, it is generally very low.
It is advisable to maintain a light diet and a good daily routine, while avoiding spicy, irritating, and greasy foods.
Increasing dietary fiber intake can also be helpful.
If symptoms persist without improvement, it is advisable to consult a physician for medication and consider a colonoscopy, although it is less likely to be necessary.

More Info

Blood in stool can be a concerning symptom and may indicate a variety of underlying conditions. The presence of blood, whether it's bright red or darker in color, can signal different issues within the gastrointestinal tract. In your case, the combination of blood in the stool, blood when wiping, and left lower abdominal pain warrants a thorough evaluation.

Possible Causes
1. Hemorrhoids: One of the most common causes of bright red blood in the stool is hemorrhoids. These are swollen veins in the lower rectum or anus that can bleed during bowel movements. The blood is usually bright red and may be seen on toilet paper or in the toilet bowl.

2. Anal Fissures: These are small tears in the lining of the anus, often caused by passing hard stools. They can cause sharp pain during bowel movements and may also result in bright red blood.

3. Diverticular Disease: Diverticulosis, which involves the formation of small pouches in the colon wall, can lead to diverticulitis if these pouches become inflamed. This condition can cause abdominal pain, fever, and changes in bowel habits, along with bleeding.

4. Colorectal Polyps or Cancer: Polyps are growths on the lining of the colon that can bleed. While not all polyps are cancerous, some can develop into colorectal cancer over time. Blood in the stool, especially if accompanied by changes in bowel habits or weight loss, should be evaluated for potential malignancy.

5. Gastrointestinal Infections: Certain infections can cause inflammation and bleeding in the gastrointestinal tract. This can be due to bacteria, viruses, or parasites.

6. Inflammatory Bowel Disease (IBD): Conditions like Crohn's disease or ulcerative colitis can cause inflammation of the intestines, leading to symptoms such as abdominal pain, diarrhea, and blood in the stool.

When to Seek Help
Given your symptoms, it is crucial to seek medical attention promptly. You should contact a healthcare provider if you experience:
- Persistent blood in the stool
- Severe abdominal pain
- Changes in bowel habits (such as diarrhea or constipation)
- Unexplained weight loss
- Fever or chills

Diagnostic Approach
A healthcare provider will likely perform a thorough history and physical examination. They may recommend tests such as:
- Blood Tests: To check for anemia and signs of infection or inflammation.

- Stool Tests: To identify any infections or blood.

- Colonoscopy: A procedure that allows the doctor to view the inside of your colon and rectum, which can help identify the source of bleeding.

- Imaging Studies: Such as a CT scan, to evaluate the abdominal organs.

Conclusion
While some causes of blood in the stool are benign, others can be serious and require immediate attention. It is essential to not ignore these symptoms, especially with the presence of abdominal pain. Early diagnosis and treatment can significantly improve outcomes and prevent complications. Please consult a healthcare professional as soon as possible to discuss your symptoms and receive appropriate care.
