The most common cause of rectal bleeding in young individuals is the rupture of a thrombosed hemorrhoid; however, a small number of cases may be due to colorectal lesions.
It is recommended to consult a colorectal surgeon for further evaluation.
Wishing you a speedy recovery.

Heavy bleeding during bowel movements can be alarming and may indicate a variety of underlying issues. While the absence of pain is a positive sign, it does not rule out the possibility of a serious condition. Here are some potential causes and considerations regarding your symptoms:
1. Hemorrhoids: One of the most common causes of rectal bleeding, especially during bowel movements, is hemorrhoids. These are swollen blood vessels in the rectal area that can become inflamed and bleed, particularly when straining during a bowel movement. The blood is usually bright red and may be seen on toilet paper or in the toilet bowl.

2. Anal Fissures: An anal fissure is a small tear in the lining of the anus, often caused by passing hard stools. While fissures can be painful, some individuals may experience bleeding without significant discomfort. The blood is typically bright red and may accompany a bowel movement.

3. Diverticular Disease: Diverticulosis and diverticulitis can lead to bleeding in the colon. Diverticulosis involves the formation of small pouches in the colon wall, which can sometimes bleed. Diverticulitis, which is the inflammation of these pouches, can also cause bleeding and may be accompanied by abdominal pain, fever, and changes in bowel habits.

4. Colorectal Polyps or Cancer: Polyps are growths on the lining of the colon that can bleed. While many polyps are benign, some can develop into colorectal cancer. Bleeding from polyps or cancer may not always be accompanied by pain, especially in the early stages.

5. Gastrointestinal Conditions: Conditions such as inflammatory bowel disease (IBD), which includes Crohn's disease and ulcerative colitis, can also lead to rectal bleeding. These conditions may present with other symptoms such as diarrhea, abdominal pain, and weight loss.

6. Infections: Certain infections of the gastrointestinal tract can cause inflammation and bleeding. This may be accompanied by diarrhea, fever, and abdominal cramps.

Given the potential seriousness of some of these conditions, it is crucial to seek medical attention. A healthcare provider will likely perform a thorough evaluation, which may include a physical examination, a review of your medical history, and possibly diagnostic tests such as a colonoscopy or imaging studies to determine the source of the bleeding.

In the meantime, here are some general recommendations:
- Avoid Straining: If you are experiencing constipation, try to avoid straining during bowel movements. Increasing fiber intake through fruits, vegetables, and whole grains can help soften stools.

- Stay Hydrated: Drinking plenty of fluids can also aid in preventing constipation.

- Monitor Symptoms: Keep track of any additional symptoms, such as changes in bowel habits, abdominal pain, or weight loss, and report these to your healthcare provider.

In conclusion, while the absence of pain may be reassuring, the presence of heavy bleeding during bowel movements warrants prompt medical evaluation to rule out serious conditions. Early diagnosis and treatment can significantly improve outcomes and help manage any underlying issues effectively.
