Inflammatory bowel disease (IBD) is a chronic inflammatory condition that affects the digestive tract, primarily the small and large intestines. It is a complex and debilitating disorder that affects millions of people worldwide, with symptoms including abdominal pain, diarrhea, rectal bleeding, fatigue, and weight loss. 

There are two main types of IBD: ulcerative colitis and Crohn's disease. Ulcerative colitis affects the inner lining of the large intestine and rectum, while Crohn's disease can affect any part of the digestive tract, from the mouth to the anus but most commonly affects small intestine ( Ileum ) and large intestine ( colon ). Both conditions can cause inflammation, ulcers, and tissue damage, which can lead to serious complications such as bowel obstruction, perforation, and colon cancer.
