How Dr. Nghia Nguyen Diagnoses Diverticulosis of the Colon with?
Dr. Nguyen uses a step-by-step approach:
Medical History and Exam
He reviews your health history, asking about the location and duration of epigastric pain, bowel-movement patterns, diet, fluid intake, and any prior gastrointestinal issues.
Blood Tests
He orders a complete blood count and inflammatory markers (CRP, ESR) to look for signs of infection, anemia or systemic inflammation.
Imaging Studies
Colonoscopy - Directly visualizes the colon lining, identifies diverticula, and assesses for subtle inflammation.
CT Scan of the Abdomen - Detects diverticulitis, abscesses, or other causes of upper-abdominal pain, and maps the extent of disease.
Stool Studies
Occult blood testing and cultures help rule out infectious causes or active bleeding in the GI tract.
Advanced Testing (if needed)
In complex cases, he may recommend MRI enterography or endoscopic ultrasound for detailed evaluation, or targeted biopsies to exclude other disorders.
