Where can Crohn's disease occur in the gastrointestinal tract?

Crohn's disease is characterized by its ability to affect any part of the gastrointestinal (GI) tract, from the mouth to the anus. This inflammatory bowel disease can result in a wide range of symptoms depending on the location of the inflammation.

The critical aspect of Crohn's disease is that it can occur in a patchy manner, leading to segments of healthy intestine interspersed with inflamed areas. This phenomenon is distinctly different from other types of inflammatory bowel disease, such as ulcerative colitis, which primarily affects the colon.

Because Crohn's can manifest in any section of the GI tract, including the esophagus, stomach, small intestine, colon, and rectum, it is essential for healthcare providers to recognize that its presence is not confined to a singular area. This knowledge is vital for appropriately diagnosing and managing the condition as well as for understanding symptoms and treatment options that may vary significantly based on which part of the GI tract is affected.
