About the Expert

Dr. Nghia Nguyen, DO, is a board-certified gastroenterologist providing advanced digestive care in the Greater Houston area. He earned his medical degree from the Texas College of Osteopathic Medicine and completed both his Internal Medicine residency and Gastroenterology fellowship at the University of Texas at Rio Grande Valley. Dr. Nguyen specializes in treating conditions such as acid reflux, irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), and liver disorders.

Common Causes and Risk Factors

  • Infection with Helicobacter pylori (H. pylori)
  • Long-term use of NSAIDs such as ibuprofen or naproxen
  • Smoking or exposure to secondhand smoke
  • Excessive alcohol consumption
  • High stress levels or poor sleep habits

Signs and Symptoms

  • Burning or aching pain in the upper abdomen, often worsening at night
  • Pain that improves temporarily after eating or taking antacids
  • Early satiety, burping, or bloating
  • Heartburn or acid reflux
  • Vomiting blood (hematemesis) or passing dark, tarry stools (melena) in severe cases

How Dr. Nghia Nguyen Diagnoses This Condition?

Dr. Nguyen uses a step-by-step approach:

Medical History and Physical Exam

He reviews your epigastric pain—its timing, severity, relationship to meals, NSAID or alcohol use—and performs a focused abdominal exam to check for tenderness or signs of complications.

Blood Tests and H. pylori Testing

We draw a CBC to look for anemia from bleeding. To detect H. pylori, we choose among a urea breath test, stool antigen test, or blood antibody screening based on your presentation.

Upper Endoscopy (EGD)

  • Direct visualization of the duodenum to identify and size the ulcer.
  • Targeted biopsies to confirm H. pylori infection and exclude other causes like malignancy.

Imaging Studies

  • Upper GI series (barium swallow) to outline ulcer location when endoscopy is inconclusive or delayed.
  • CT scan of the abdomen if complications such as perforation, obstruction, or abscess are suspected.

Advanced Testing (if needed)

For refractory or atypical cases, tests like gastric pH monitoring or motility studies may be ordered to evaluate acid exposure or gastric emptying.
