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

  • Certain foods (beans, onions, broccoli, carbonated drinks)
  • Eating habits (eating too quickly or consuming large meals)
  • Digestive issues (IBS, SIBO - small intestinal bacterial overgrowth)
  • Food sensitivities (lactose intolerance, gluten sensitivity)
  • Hormonal changes (e.g., menstrual cycle fluctuations)
  • Medications (some pain relievers or antibiotics)
  • Stress and anxiety
  • Inactive lifestyle
  • History of gastrointestinal problems

Signs and Symptoms

  • Belly feels tight, swollen, or full
  • Pain or abdominal cramps
  • Frequent burping or passing gas
  • Feeling full after eating only a small amount
  • Constipation or diarrhea

How Dr. Nghia Nguyen Diagnoses Bloating?

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

Medical History and Physical Exam

He reviews your symptoms (bloating, fullness, upper abdominal discomfort), dietary habits, lifestyle factors, menstrual history (if applicable), and performs a thorough abdominal and epigastric examination.

Blood Tests

We check for celiac disease antibodies, H. pylori infection markers, complete blood count and inflammatory markers to rule out systemic or malabsorptive conditions.

Imaging Studies

  • Abdominal ultrasound to evaluate gallbladder, liver, and pancreas for stones or structural issues.
  • CT scan of the abdomen if more detailed cross-sectional imaging is needed to identify masses or inflammation.

Advanced Testing (if needed)

Breath tests for lactose intolerance and SIBO. Upper endoscopy inspects the esophagus, stomach, and duodenum for ulcers or gastritis. Colonoscopy examines the colon and can remove polyps or take biopsies.
