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.
In ulcerative colitis, constipation may be a symptom of inflammation of the rectum (known as proctitis). The loss of fluid and nutrients from diarrhea and chronic inflammation of the bowel can also cause fever, fatigue, weight loss, and malnutrition. Pain is usually from the abdominal cramping, which is caused by irritation of the nerves and muscles that control intestinal contractions.
