Experiencing large amounts of blood during bowel movements can be alarming and warrants immediate medical attention. Based on your description, it seems you have been experiencing intermittent episodes of bright red blood during bowel movements, accompanied by blood clots resembling jelly. While it is understandable to be concerned about serious conditions such as colorectal cancer, there are several potential causes for your symptoms that should be considered.

One common cause of bright red blood in the stool is hemorrhoids, particularly internal hemorrhoids. These are swollen blood vessels in the rectum that can bleed during bowel movements, especially if you are straining or if the stool is hard. However, the presence of blood clots and the volume of blood you describe could indicate a more serious condition, such as a rectal or colon issue.

Another possibility is a rectal fissure, which is a small tear in the lining of the anus that can occur during the passage of hard stools. This can cause sharp pain and bleeding, but you mentioned that you do not experience pain, which makes this less likely.

More concerning possibilities include diverticular disease, which involves the formation of small pouches in the colon that can become inflamed or bleed, and colorectal polyps or cancer. While your age and lack of family history of cancer may lower your risk, it is still essential to rule out these conditions, especially given the recurrent nature of your symptoms.

Given that you have experienced this bleeding multiple times over several months, it is crucial to seek medical evaluation. A gastroenterologist can perform a thorough assessment, which may include a physical examination, a digital rectal exam, and possibly a colonoscopy. A colonoscopy is particularly important as it allows direct visualization of the colon and rectum, enabling the physician to identify any abnormalities, take biopsies if necessary, and provide appropriate treatment.

In the meantime, it is advisable to avoid straining during bowel movements. You can do this by increasing your fiber intake through fruits, vegetables, and whole grains, which can help soften your stool. Staying well-hydrated is also essential. Over-the-counter stool softeners or fiber supplements may be beneficial, but consult with a healthcare provider before starting any new medication.

In summary, while hemorrhoids are a common cause of rectal bleeding, the volume of blood and the presence of clots in your case necessitate a thorough evaluation to rule out more serious conditions. Please do not delay seeking medical attention, as timely diagnosis and treatment are crucial for your health.
