Proctitis is rather common condition that is primarily characterized by the inflammation of the lining of the rectum and can exist in acute or chronic versions. There are a number of likely proctitis causes including radiation therapy and antibiotics ingestion. Proctitis is also known to be a rather common symptom of the presence of some other conditions, including sexually transmitted ones such as gonorrhea, Chlamydia and herpes. Some of the other proctits causes include bacterial infection, allergies and malfunction of the nerve groups located around the rectum.Some of the more common proctitis symptoms include a regular urge to have a bowel movement, rectal pain and bleeding, diarrhea as well as pain felt on the left side of the abdomen. It is important to undergo proctitis treatment as soon as possible as some of the complications that can develop as a result of ignoring the condition include anemia – as a result of the continuous loss of blood through the rectum; as well as the development of ulcers and fistulas.
