Despite consuming gluten free diet for 2 months, there was no improvement in her health. Celiac serology was repeated which did not show any change - i.e., her tTG was still elevated. A gastroenterologist was referred to who advised her to restart gluten for 2 months and come back for an endoscopy.

The endoscopy finding showed that she had an extensive gastritis secondary to Helicobacter pylori (a bacterial infection of the stomach) and her duodenal biopsy was not suggestive of celiac disease.  She was treated for the bacterial infection after which her abdominal pain vanished, even though she continued to consume gluten.

After 3 months of completion of the treatment, her tTG antibody report was negative.
