Hi, Bright red bleeding indicates that bleeding is from colon or rectum. Usual causes of continuous long bleeding may be hemorrhoids, fissure, polyps or even colorectal cancer etc. Usually external hemorrhoids can be felt by presence of a outside lump or bulge particularly during act of defecation. Similarly presence of a fissure or external hemorrhoids can be diagnosed by a doctor just on external examination or examination by anoscope. External hemorrhoids and fissure will generally cause pain during act of defecation. If the bleeding is painless, then other causes of bleeding like internal hemorrhoids, polyps, inflammatory diseases or colorectal cancer may have to be looked for by colonoscopy to diagnose for a cause and also for the biopsy from suspected lesions. Treatment will depend upon the cause of bleeding. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Satnarain Bansal, General & Family Physician
