How Dr. Scott Diagnoses This Condition?
Dr. Scott uses a step-by-step approach:
Medical History and Physical Exam
He reviews your symptoms (including epigastric pain), family history of celiac disease or other autoimmune disorders, and any previous gut issues.
Blood Tests
We check for celiac-specific antibodies such as tissue transglutaminase IgA (tTG-IgA) and total IgA levels to screen for an immune response to gluten.
Genetic Testing
When the diagnosis is uncertain, testing for HLA-DQ2 and HLA-DQ8 genes helps determine your genetic predisposition to celiac disease.
Endoscopy with Biopsy
An upper endoscopy allows Dr. Scott to take small samples from your small intestine. Microscopic examination confirms villous atrophy and other gluten-related changes.
Additional Testing (if needed)
Capsule endoscopy to visualize areas beyond the reach of a standard scope if symptoms persist.
Nutritional assessment for deficiencies (iron, vitamin D, calcium) to guide supplement recommendations.
