Pseudomembranous Colitis - Signs and Symptoms

Signs and Symptoms

As noted above, pseudomembranous colitis is characterized by diarrhea, abdominal pain, and fever. Usually, the diarrhea is non-bloody, although blood may be present if the affected individual is taking blood thinners or has an underlying lower bowel condition such as inflamed hemorrhoids. Abdominal pain is almost always present and may be severe. So-called "peritoneal" signs (e.g., rebound tenderness) may be present. "Constitutional" signs such as fever, fatigue, and loss of appetite are prominent. In fact, one of the main ways of distinguishing pseudomembranous colitis from other antibiotic-associated diarrheal states is that patients with the former are sick. That is, they are often prostrate, lethargic, and in general look unwell. Their "sick" appearance tends to be paralleled by the results of their blood tests, which often show anemia, an elevated white blood cell count, and low serum albumin.
