If you are experiencing rectal bleeding only during large bowel movements, and it is bright red in color, it is likely due to hemorrhoids. This condition is not usually a cause for concern and can be managed with over-the-counter treatments like Anusol™ ointment. It is important to also address any underlying constipation that may be contributing to the issue by maintaining a diet high in fiber, staying hydrated, and practicing good bathroom habits. If symptoms persist beyond 7 days, it is recommended to consult a healthcare professional.
