Inflammatory Bowel Disease (IBD) is a group of chronic inflammatory conditions of the gastrointestinal tract, primarily including Crohn's disease and ulcerative colitis. These conditions result in symptoms such as abdominal pain, diarrhea, rectal bleeding, weight loss, and fatigue. The exact cause is unknown, but it involves an abnormal immune response. Treatment aims to reduce inflammation and manage symptoms through medications (e.g., anti-inflammatory drugs, immunosuppressants, biologics), dietary adjustments, and sometimes surgery in severe cases.
