Ulcerative Colitis - When To Call a Doctor. Call a doctor immediately if you have been diagnosed with ulcerative colitis and you have: 1  Fever over 101Â°F (38.3Â°C) or shaking chills. 2  Lightheadedness, passing out, or rapid heart rate.  Stools that are almost always bloody.
One type of bacteria in particular, a species called Clostridium difficile (C. difficile), can overgrow inside the bowel, producing irritating chemicals that damage the bowel wall and trigger bowel inflammation, called colitis. This can cause abdominal pain, cramps, diarrhea, and fever. In some cases, high-volume, diarrhea is so frequent that the person develops dehydration (very low levels of body water). A more severe complication of C. difficile overgrowth can lead to a type of bowel inflammation called pseudomembranous colitis.
