By Mayo Clinic staff

Proctitis is an inflammation of the lining of your rectum. Sexually transmitted diseases (STDs) are the most common cause, but other causes include inflammatory bowel diseases and non-sexually transmitted infections.

Proctitis may also be a side effect of some medical treatments, including radiation therapy, or antibiotic use.

Sexually transmitted proctitis is most common in people who engage in anal or oral-anal intercourse, particularly if they have multiple partners. Proctitis in general mainly affects adult males.

You may find proctitis to be short-lived, or it may become chronic. In most cases, though, you'll be able to clear up proctitis with treatment. Treatment for proctitis depends on the cause.
