Inflammatory bowel diseases (IBD) are a group of chronic conditions that cause inflammation in the digestive tract. The two main types of IBD are Crohn's disease and ulcerative colitis. Symptoms often include abdominal pain, diarrhea, weight loss, and fatigue, which can significantly impact a person's quality of life. The exact cause of IBD is not fully understood, but it is believed to involve a combination of genetic, environmental, and immune system factors. Diagnosis typically involves medical history, physical exams, and tests such as endoscopy or imaging studies. Treatment options may include medications, dietary changes, and sometimes surgery.
