Causes
The exact causes of IBD are unknown, but some hypotheses include:
- Heredity—having another family member with IBD
- Contracting a germ or infection that affects the intestinal tract
- Compromised immune system or infection that affects the immune system
IBD is not a contagious infection, so it cannot be passed from person to person.
