Hi. Thanks for your query. Noted the history and understood the concerns. Recurrent anal bleeding for a few days particularly when there is change in timetable especially food can be due to the following reasons: Hemorrhoid, also called as piles. Fissure-in-ano with or without piles. Polyp, ulcer, cancer are rare causes. Since this is a problem since long one should get the proper clinical evaluation, per-rectal digital examination and ano-proctoscopy. Colonoscopy should also be done to make sure that nothing is missed from the colon. Yes, there is a need for endoscopy in the form of colonoscopy. Also do the following: Be correct on timetable. Avoid all the foods and beverages that increase or instigate the problems. Sitz bath in a tub with warm water. Stool softeners if required to keep the stools soft. If a cause is found which needs surgery, get this done too.
