Inflammatory bowel disease, or IBD, comprises a group of disorders characterized by persistent inflammation or ulceration of the gastrointestinal tract.
Risk factors for IBD include genetic predisposition, altered immune response to gut microorganisms, medications such as antibiotics, lifestyle factors like smoking, and stress.
The two primary types of IBD are ulcerative colitis and Crohn's disease.
Ulcerative colitis affects the mucosal and submucosal layers of the colon and rectum, with lesions that appear sequentially.
The affected mucosa shows ulceration, diffuse inflammation, and epithelial desquamation, sometimes leading to bleeding.
Over time, muscular hypertrophy causes bowel narrowing and thickening.
The predominant manifestations of ulcerative colitis include diarrhea with blood or mucus, left lower quadrant abdominal pain, and intermittent tenesmus.
Other manifestations include anorexia, fever, vomiting, and extraintestinal manifestations such as skin and eye lesions and enteropathic arthritis, which typically affects the peripheral joints, such as the knees.
