Classification
| Category | Description |
|---|---|
| Stool frequency | 0 normal; 1 one to two stools a day more than normal; 2 three to four more; 3 five or more more than normal |
| Rectal bleeding | 0 none; 1 streaks of blood with stool less than half the time; 2 obvious blood with stool most of the time; 3 blood passed alone |
| Endoscopic subscore (Mayo endoscopic score) | 0 normal or inactive; 1 mild (erythema, reduced vascular pattern, mild friability); 2 moderate (marked erythema, absent vascular pattern, friability, erosions); 3 severe (spontaneous bleeding, ulceration) |
| Physician's global assessment | 0 normal; 1 mild; 2 moderate; 3 severe disease |
