Symptoms of indeterminate colitis
Symptoms of indeterminate colitis are similar to those of Crohn’s and ulcerative colitis, including abdominal pain and cramping, diarrhea, fatigue, and weight loss. It usually does not feature rectal bleeding and other types of gastrointestinal bleeding as it happens in inflammatory bowel disease.
To diagnose colitis, the doctor must take a complete medical history, perform a physical examination and order appropriate laboratory tests. These tests may include stool culture and sensitivity; C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR); complete blood count; thyroid function test; electrolytes; and sometimes a colonoscopy or flexible sigmoidoscopy if they need to rule out a more severe condition.
