Do you have to eat gluten before celiac biopsy?

What diseases can be detected by an endoscopy biopsy?

Upper GI endoscopy can be used to identify many different diseases:

  • gastroesophageal reflux disease.
  • ulcers.
  • cancer link.
  • inflammation, or swelling.
  • precancerous abnormalities such as Barrett’s esophagus.
  • celiac disease.
  • strictures or narrowing of the esophagus.
  • blockages.

Should I stop eating gluten before my endoscopy?

It is very important that you do not start a gluten-free diet before testing and diagnosis. Once on a gluten-free diet, antibodies to gluten will start to drop in the blood and the intestine will start to heal and there is a risk of a false negative result on both the blood test and endoscopy.

Is biopsy required for celiac?

Because the damage caused by celiac disease is microscopic, in a majority of cases it is not possible to confirm the diagnosis of celiac disease just by looking at the walls of the intestine. That’s why a biopsy is needed.

Can an endoscopy detect gluten intolerance?

If you had a biopsy, the results will be ready in about 7 days. Your healthcare provider will talk with you about any more testing or treatment that is needed.
