| Crohn’s | Ulcerative colitis | |
|---|---|---|
| Frequency/type of defecation | increased, typically non-bloody diarrhea | greatly increased, bloody diarrhea w/ mucus |
| Nutritional status | poor or malnourished | since ulcerative colitis does not affect small intestine, absorption of nutrients is not impaired → mostly normal but wt loss + malnutrition can still occur in severe disease |
| PE | constant RLQ pain, palpable abdominal mass | painful defecation, pain located in LLQ |
