How Is Each Type of Crohn's Disease Different?

Jejunoileitis causes inflammation of the jejunum, which is the upper half of the small intestine. Symptoms of this type of Crohn’s disease range from mild to severe and include abdominal pain, cramping, and diarrhea. Around 20% of children with Crohn’s have this type of disease and it may delay their growth or puberty. Although it is rare, in its most severe form, jejunoileitis can trigger the formation of fistulas, arthritis or skin lesions.
