Ask a Doctor

A coworker of mine has Crohn's disease and I’m worried I might contract it. Is Crohn's disease contagious?

Doctor’s Response

No, Crohn's disease is not contagious.

Crohn's disease is a chronic inflammatory condition of the GI (gastrointestinal tract), and can appear anywhere in the GI tract. The exact cause of Crohn's disease remains unknown.

  • Current theories suggest that genetics, environment, diet, blood vessel abnormalities, and/or even psychosocial factors cause Crohn's disease.
  • Probably the most popular theory is that Crohn's disease is caused by the immune system overreacting to infection by a virus or bacterium.
  • Crohn's disease apparently is not caused by emotional distress.
  • Crohn's disease definitely runs in families. People who have Crohn's disease may have an inherited predisposition to abnormal immunologic response to one or more provoking factors.
