What are the types of Crohn’s disease?

Crohn’s disease can affect different sections of the digestive tract. Types of Crohn’s disease include:

• Ileocolitis: Inflammation occurs in the small intestine and part of the large intestine, or colon. Ileocolitis is the most common type of Crohn’s disease.
• Ileitis: Swelling and inflammation develop in the small intestine (ileum).
• Gastroduodenal: Inflammation and irritation affect the stomach and the top of the small intestine (the duodenum).
• Jejunoileitis: Patchy areas of inflammation develop in the upper half of the small intestine (called the jejunum).
