Proctitis

Proctitis is an inflammation of the rectum. It can cause discomfort, bleeding, and the discharge of mucus or pus.

Alternative Names

Inflammation - rectum; Rectal inflammation

Causes, incidence, and risk factors

There are many causes of proctitis. They can be grouped as follows:

  • Autoimmune disease
  • Harmful substances
  • Non-sexually transmitted infection
  • Sexually transmitted disease (STD)

Proctitis caused by STD is common in people who have anal intercourse. STDs that can cause proctitis include gonorrhea , herpes, chlamydia , and lymphogranuloma venereum .

Infections that are not sexually transmitted are less common than STD proctitis. One type of proctitis not from an STD is an infection in children that is caused by the same bacteria as strep throat.

Autoimmune proctitis is linked to diseases such as ulcerative colitis or Crohn's disease . If the inflammation is in the rectum only, it may come and go or move upward into the large intestine.

Proctitis may also be caused by some medicines, radiotherapy or inserting harmful substances into the rectum.

Risk factors include:
