How Dr. Nghia Nguyen Diagnoses Appendicitis?
Dr. Nguyen uses a step-by-step approach:
Medical History and Physical Exam
She asks about your pain—often starting as a dull, epigastric ache that shifts to the lower right quadrant—and checks your abdomen for tenderness, rebound pain, and guarding.
Blood Tests
We draw blood to measure white blood cell count and C-reactive protein, which rise in the presence of infection.
Imaging Studies
Abdominal ultrasound evaluates the size of the appendix, looks for wall thickening, and detects any surrounding fluid.
CT scan provides high-resolution images to confirm appendiceal inflammation, rule out alternative diagnoses, and assess for complications.
Staging and Risk Assessment
Dr. Nguyen explains the four stages—from initial inflammation to possible perforation—to determine urgency and tailor your treatment plan.

What does appendicitis feel like?
It usually starts as a dull ache near your belly button and then shifts to a sharper pain in the lower right abdomen.
What food can cause appendicitis?
No specific food directly causes appendicitis. However, a low-fiber, high-fat diet may increase your risk.
