Diagnosis typically involves a detailed medical history and physical examination. Additional diagnostic tests may include:
Stool tests: To check for infections, blood, or other abnormalities. Blood tests: To evaluate for anemia or inflammatory markers. Endoscopy: Procedures like colonoscopy or sigmoidoscopy to visualize the GI tract and identify the source of bleeding. Imaging studies: Ultrasound, CT scan, or MRI to provide detailed images of the GI tract.
