### Patient: Doctor, I have been experiencing abdominal pain, diarrhea, and blood in my stool. I am also constantly tired and fatigued.
### Doctor: Based on your symptoms, it's possible that you have ulcerative colitis. We will need to perform a series of medical tests to confirm your diagnosis. These include a blood test, CBC, sigmoidoscopy or colonoscopy, glucose measurement, IV fluid replacement, electrolyte panel, and a CT scan.
