Inflammatory bowel disease (IBD) causes inflammation in the gastrointestinal tract and can result from unhealthy lifestyles and poor dietary choices. It encompasses conditions like microscopic colitis, pouchitis, Crohn's disease, and ulcerative colitis, each affecting different parts of the digestive system. Early detection and treatment with various medications, along with lifestyle changes such as a high-fiber diet and regular exercise, can effectively manage the disease.
