Common Causes and Risk Factors
Family history of celiac disease
Presence of HLA-DQ2 or HLA-DQ8 genes
Other autoimmune conditions (e.g., Type 1 diabetes, thyroid disease)
History of gastrointestinal infections or major illness
He reviews your epigastric pain or upper-abdominal discomfort, leg swelling, fatigue, and your heart‐failure history and risk factors.
Blood Tests
We check liver enzymes (AST, ALT), bilirubin, albumin, and heart-failure biomarkers to rule out other causes of liver injury.
Imaging Studies
Liver ultrasound or elastography to measure stiffness and assess venous congestion.
Echocardiogram to evaluate cardiac function, right-sided pressures, and their effect on the liver.
Advanced Testing (if needed)
Rarely, a liver biopsy confirms the degree of fibrosis. In select cases, right-heart catheterization or cardiac MRI may be used for precise pressure measurements.
Treatment
Our Team offers a full range of care for celiac disease.

Personalized gluten-free meal plans developed by Dr. Scott and our registered dietitians
Switching to naturally gluten-free grains such as rice, corn, and quinoa

Short-term use of probiotics or anti-diarrheal medications to ease digestive discomfort
3. Minimally Invasive or Advanced Procedures
Endoscopic biopsy to assess intestinal damage and monitor healing
Specialized imaging to evaluate inflammation or strictures in the small intestine

Frequently Asked Questions
When should I get tested for celiac disease?
If you have stomach problems that don't go away or a family history of the condition, it's a good idea to talk to Dr. Scott about testing.
How is celiac disease different from gluten intolerance?
Celiac disease causes immune-driven damage to the small intestine. Gluten intolerance may cause discomfort but does not lead to lasting gut injury.
Can I stop eating gluten before getting tested?
No. You must keep eating gluten while testing is in progress-stopping gluten too early can lead to false-negative results.
How long does it take to feel better on a gluten-free diet?
Many patients notice relief within weeks, but full intestinal healing can take several months.
Is celiac disease passed down through families?
Yes. First-degree relatives have a higher risk, and genetic markers (HLA-DQ2/DQ8) can indicate predisposition.
Can I eat oats if I have celiac disease?
Yes-only oats labeled “gluten-free.” Regular oats are often processed with wheat and can be contaminated.
Is treatment different for children?
The diagnosis is the same, but dietary plans are adjusted to a child's needs, often with support from pediatric dietitians.
