| | Inflammatory Bowel Disease |
 | | Active disease in ulcerative colitis is characterized by the endoscopic appearance of superficial ulcerations, friability, a distorted mucosal vascular pattern, and exudate. |
 | | The inflammation is localized in the ileocecal region in 50% of cases, the small bowel in 25% of cases, the colon in 20% of cases, and the upper gastrointestinal tract or perirectum in 5%. |
 | | Moderate to severe disease describes the disorder in patients who have failed to respond to therapy for mild/moderate disease, or to those with fevers, weight loss, abdominal pain, anemia, or nausea/vomiting without frank obstruction. |
