What are the causes for Proctitis?

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

  • Inflammatory bowel disease
  • 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 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 to prostate or pelvis or inserting harmful substances into the rectum.

Risk factors include:

  • Autoimmune disorders, including inflammatory bowel disease
  • High-risk sexual practices, such as anal sex

What are the symptoms for Proctitis?

Symptoms include:

  • Bloody stools
  • Constipation
  • Rectal bleeding
  • Rectal discharge, pus
  • Rectal pain or discomfort
  • Tenesmus (pain with bowel movement)

What are the current treatments for Proctitis?

Most of the time, proctitis will go away when the cause of the problem is treated. Antibiotics are used if an infection is causing the problem.

Corticosteroids or mesalamine suppositories or enemas may relieve symptoms for some people.

What is the outlook (prognosis) for Proctitis?

The outcome is good with treatment.

What are the possible complications for Proctitis?

Complications may include:

  • Anal fistula
  • Anemia
  • Recto-vaginal fistula (women)
  • Severe bleeding

When should I contact a medical professional for Proctitis?

Call your health care provider if you have symptoms of proctitis.

How do I prevent Proctitis?

Safe sex practices may help prevent the spread of the disease.
