How Dr. Nghia Nguyen Diagnoses?
Dr. Nguyen uses a step-by-step approach:
Medical History & Physical Exam
He reviews your pain characteristics (onset, location, quality, duration), triggers (food, stress), and associated symptoms such as nausea, bloating or heartburn.
Laboratory Tests
He orders blood work including a complete blood count, liver function tests, pancreatic enzymes (amylase/lipase) and H. pylori testing to rule out infection.
Imaging Studies
Abdominal ultrasound to evaluate the gallbladder, liver and pancreas.
CT scan of the abdomen when more detailed visualization is needed.
Endoscopic Evaluation
An upper endoscopy (EGD) allows direct inspection of the esophagus, stomach and duodenum to detect ulcers, inflammation or other lesions.
Advanced Testing (if needed)
For persistent or unexplained pain, tests such as gastric emptying studies, esophageal pH monitoring or motility studies may be performed.
