Crohn’s disease is a chronic inflammatory bowel disease.
According to the National Institute of Diabetes and Digestive and Kidney Diseases, Crohn’s disease causes inflammation in the digestive tract. It can affect different parts of the gastrointestinal tract, and symptoms and severity can vary.
Diagnosis generally depends on medical history, physical examination, laboratory testing, imaging, endoscopy, and other information. Treatment plans are individualized and may change over time.
