Anus and rectum can be afflicted by diseases  such as piles, fistula, fissure, rectal prolapse and cancers. The first four are common ailments but are infrequently reported by patients. They feel embarrassed to share it even with their friends and relatives. Sometimes the spouse also is not aware. This can be dangerous since a long standing bleeding in stools due to piles and fissure can lead to anemia or low iron in the body. These patients may present with weakness, breathlessness and hair loss.
