Patients with severe presentations of ulcerative colitis are generally categorized as having either severe or fulminant ulcerative colitis:
●Patients with a severe ulcerative colitis have frequent loose bloody stools (≥6 per day) with severe cramps and evidence of systemic toxicity as demonstrated by a fever (temperature ≥37.5°C), tachycardia (heart rate [HR] ≥90 beats/minute), anemia (hemoglobin <10.5 g/dL), or an elevated erythrocyte sedimentation rate (ESR) (≥30 mm/hour). Patients may have rapid weight loss.
●Fulminant colitis refers to a subgroup of patients with severe ulcerative colitis who have more than 10 stools per day, continuous bleeding, abdominal pain, distension, and acute, severe toxic symptoms including fever and anorexia. Such patients are at risk of progressing to toxic megacolon and bowel perforation.
tachycardia is not uncommon.
