Celiac Disease: Celiac disease (gluten-sensitivity) presents with villous atrophy, malabsorption, weight loss (signs of nutrient or vitamin deficiency). Resolution of the mucosal lesions and symptoms after withdrawal of gluten-containing foods (usually within a few weeks to months). Blood test can determine if you have this condition. Gluten-free products are clearly labeled. Pure oatmeal does not contain gluten.

Probably a week: Most gluten would be gone in less than a day but to be totally free may take longer. Blood test for gluten sensitivity is unreliable if done on a gluten-free diet. Gluten is present in wheat, barley, and rye. Oat is ok if grown in fields uncontaminated by gluten-containing crop. About 1% of the population is gluten sensitive but studies suggest that non-celiac gluten intolerance can be present.
