Fluid retention due to heart, liver, or kidney issues
Tumors, strictures, or intestinal blockages
Lack of physical activity or high stress levels

How Dr. Nghia Nguyen Diagnoses Abdominal Distension?
Dr. Nguyen uses a step-by-step approach:
Medical History and Physical Exam
She reviews your diet, bowel habits, weight changes and performs an abdominal exam to check for swelling, tenderness, or fluid.
Blood Tests
We assess a complete blood count, liver function tests, and metabolic panel to look for infection, inflammation, or organ dysfunction.
Imaging Studies
Abdominal ultrasound to detect fluid buildup, organ enlargement, gallstones, or ascites.
CT scan of the abdomen and pelvis for detailed views of the intestines, blockages, or masses.
Breath Tests and Endoscopy
Lactose and SIBO breath tests to identify food intolerances or bacterial overgrowth.
Upper endoscopy to visualize the esophagus, stomach, and duodenum for ulcers, inflammation, or hiatal hernia.
Advanced Procedures (if needed)
Capsule endoscopy may be used to inspect the small intestine, and paracentesis can remove excess fluid for analysis. Dr. Nguyen tailors these only when initial tests are inconclusive.

Frequently Asked Questions
What's the difference between abdominal distension and fat?
Abdominal distension is a temporary swelling caused by gas or fluid buildup. Fat accumulates slowly over time and doesn't disappear after meals.
Can abdominal distension cause back pain?
Yes. Excess gas or fluid can press on your back muscles and spine, leading to discomfort or pain.
How long does treatment for bloating take?
Many patients notice improvement within 2-4 weeks when following dietary adjustments and basic medications as recommended by Dr. Nguyen.
Do I need diagnostic testing for every case?
No. Mild cases often resolve with lifestyle and diet changes. Dr. Nguyen orders blood work, imaging, or endoscopy only when clinically necessary.
Is abdominal distension ever serious?
Most cases are benign. However, if your abdomen swells suddenly and you cannot pass gas or stool, seek immediate care—this could signal an obstruction.
Will I need surgery to treat distension?
Surgery is rarely required. Treatment usually begins with noninvasive steps—diet, medications, and gentle procedures—to relieve symptoms.
Does insurance cover evaluation and treatment?
Yes. Most insurance plans cover office visits, testing, and prescribed therapies. Our team can assist you in verifying your specific benefits.
