IBD stands for Inflammatory Bowel Disease, which is a term used to describe a group of chronic inflammatory conditions that affect the digestive tract. The two main types of IBD are Crohn's disease and ulcerative colitis. The exact cause of IBD is not known, but it is believed to involve a combination of genetic, environmental, and immune system factors. There is currently no cure for IBD, but various treatments are available to manage the symptoms and reduce inflammation. A carnivore diet may help.
