Clinical Features
Ulcerative Colitis
- Cardinal symptoms: Bloody diarrhea, frequent, small volume
- Associated symptoms: Colicky abdominal pain, tenesmus, urgency
- Characterized by a relapsing and remitting course
Crohn's Disease
- Chronic diarrhea, abdominal pain, weight loss
- Abdominal mass, perianal lesions, stomatitis, fissures and fistulas
- Malaise, fever, anorexia are more common with CD than UC
Risk Factors
- Smoking is a risk factor for CD but has a protective factor for UC through unknown mechanism
- Age - most people are diagnosed between 15 and 35 years
- Early-onset (occurring <40 years) disease is more aggressive and has a less favorable course, requiring more immunomodulators and surgical intervention compared with late-onset disease
- UC affects men and women equally, while CD is more frequent in women
- Family history
- Recent episodes of infectious gastroenteritis
- Use of non-selective nonsteroidal anti-inflammatory drugs (NSAIDs) may exacerbate UC
- Appendectomy for proven appendicitis during childhood or adolescence is associated with reduced risk of UC in adulthood
