Celiac disease is a chronic autoimmune disorder where the ingestion of gluten (a protein found in wheat, barley, and rye) triggers an immune response that damages the small intestine lining. This damage impairs nutrient absorption and can lead to various gastrointestinal and systemic symptoms.
He evaluates your dietary habits, family history of autoimmune conditions, and symptoms like digestive issues, fatigue, or rashes.
We perform serologic tests to detect specific antibodies such as tTG-IgA and EMA, which are commonly elevated in celiac disease.
HLA-DQ2 and HLA-DQ8 gene testing may be done to support diagnosis, especially in unclear cases or if antibody tests are inconclusive.
If the patient has already been avoiding gluten, Dr. Rishi may recommend a temporary gluten challenge before testing to ensure accurate results.

Through blood tests to check for celiac antibodies (like tTG-IgA) followed by a small intestine biopsy via endoscopy.
No. Accurate diagnosis requires lab blood work and physician-supervised exams.
The primary test is tTG-IgA along with total IgA levels to rule out IgA deficiency.
You may need a medically supervised gluten challenge before testing to ensure reliable results.
The official code for celiac disease is K90.0.
Yes, maintain a strict gluten-free diet and join local support groups for guidance and recipes.
Many patients notice symptom relief within weeks; full intestinal healing can take several months.
