Gluten exposure

Gluten exposure is a celiac reaction from gluten reaching the small intestine. The source might be a contaminated kitchen, a mislabeled product, a restaurant kitchen with a shared fryer, or a sauce thickened with wheat flour that nobody flagged. It happens to most people with celiac at some point, even those who have been on the diet for years.

The colloquial term is "glutening." It is used the way "exposure" is used in other allergy and autoimmune contexts.

Symptoms vary widely. Some people have an acute reaction within hours (digestive distress, fatigue, brain fog, headache). Some have a delayed reaction over days. Some are silent symptomatically but still experience intestinal damage; the damage and the symptoms are not always linked. The variability is one of the harder pieces of the diet to manage, because a household cannot always rely on symptoms as feedback.

Recovery time also varies. A small exposure with mild symptoms may pass in a day or two. A larger exposure can take weeks. The diet stays the same throughout; gluten exposure does not change the prescription, it just reminds the household why the prescription is strict.

For Gluten Hero, gluten exposure does not get a special log entry. The events that produce it (a meal at a restaurant, a product purchase, a trip) are logged like any other item or trip. The medical follow-up (a visit to the gastroenterologist, a follow-up blood test) is logged as a medical expense if it happens, with the household's usual judgment about what counts.
