Inflammatory Bowl Disease (IBD) is a disease that causes chronic inflammation in the gastrointestinal tract, develops from adolescents and accompanies symptoms such as abdominal pain, fever, diarrhea, and melena. In general, it is classified into two types. Ulcerative colitis is a type of diffuse non-specific inflammation of the large intestine that mainly invades the mucous layers and forms rubbles or ulcers, accompanied by various systemic symptoms including bloody diarrhea. Crohn's disease is an unknown granulomatous inflammatory lesion in which ulcers, fibrosis, stenosis, and lesions advance from the mucous membrane to the entire intestine discontinuously, accompanied by systemic symptoms such as abdominal pain, chronic diarrhea, fever, and malnutrition.
