The test may be performed in people with suspected gluten-related disorders in very specific occasions and under medical supervision, for example in people who had started a gluten-free diet without performing duodenal biopsy. [1] [2] [3] Gluten challenge is discouraged before the age of 5 years and during pubertal growth. [4]
A trial of gluten reintroduction to observe any reaction after one to two years of strict gluten-free diet might be performed. [6] A strict gluten-free diet is effective in most of the neurological disorders associated with NCGS, ameliorating or even resolving the symptoms. It should be started as soon as possible to improve the prognosis. [1]
To assist in diagnosis, a doctor may order an HbA1c test, which measures the blood sugar average over the two or three months before the test. The more specific 6-hour glucose tolerance test can be used to chart changes in the patient's blood sugar levels before ingestion of a special glucose drink and at regular intervals during the six hours ...
Coeliac disease (British English) or celiac disease (American English) is a long-term autoimmune disorder, primarily affecting the small intestine, where individuals develop intolerance to gluten, present in foods such as wheat, rye, spelt and barley. [10]
Theoretically, a trial of gluten reintroduction to observe reaction after 1–2 years of strict gluten-free diet might be advisable. [37] Approximately one-third of persons with NCGS continue having symptoms despite gluten withdrawal. This may be due to diagnostic error, poor dietary compliance, or other reasons.
Food intolerance is a detrimental reaction, often delayed, to a food, beverage, food additive, or compound found in foods that produces symptoms in one or more body organs and systems, but generally refers to reactions other than food allergy. Food hypersensitivity is used to refer broadly to both food intolerances and food allergies.
The gastrocolic reflex or gastrocolic response is a physiological reflex that controls the motility, or peristalsis, of the gastrointestinal tract following a meal. It involves an increase in motility of the colon consisting primarily of giant migrating contractions, in response to stretch in the stomach following ingestion and byproducts of digestion entering the small intestine.

Allergic reactions are abnormal immune responses that develop after exposure to a given food allergen. [15] Food allergens account for about 90% of all allergic reactions. [ 16 ] The most common food allergens include milk , eggs , peanuts , tree nuts , fish , shellfish , soy , and wheat , [ 17 ] which are referred to as "the big eight", and ...
