Most of the times, the cause of colitis is not known.

Causes of colitis include:

  • Infections caused by a virus or a parasite
  • Food poisoning due to bacteria
  • Crohn disease
  • Ulcerative colitis
  • Lack of blood flow (ischemic colitis)
  • Past radiation to the large bowel (radiation colitis and strictures)
  • Necrotizing enterocolitis in newborns
  • Pseudomembranous colitis caused by Clostridium difficile infection

What are the symptoms for Colitis?

Symptoms can include:

  • Abdominal pain and bloating that may be constant or come and go
  • Bloody stools 
  • Constant urge to have a bowel movement (tenesmus)
  • Dehydration

  • Fever

What are the current treatments for Colitis?

What is the outlook (prognosis) for Colitis?

The outlook depends on the cause of the problem.

  • Crohn disease is a chronic condition which has no cure but can be controlled.
  • Ulcerative colitis can usually be controlled with medicines. If not controlled, it can be cured by surgically removing the colon.
  • Viral, bacterial and parasitic colitis can be cured with appropriate medicines.
  • Pseudomembranous colitis can usually be cured with appropriate antibiotics.

What are the possible complications for Colitis?

Complications may include:

  • Bleeding with bowel movements
  • Perforation of the colon
  • Toxic megacolon
  • Sore (ulceration)

When should I contact a medical professional for Colitis?
