What would a positive response to a 6–8 week elimination diet indicate?

What would a positive response to a 6–8 week elimination diet indicate?

• A. Confirmation of food-responsive enteropathy (FRD).
• B. Indicates infectious cause.
• C. Indicates autoimmune disease.
• D. Indicates neoplasia.

Answer: (A)

The key idea is that a sustained improvement on a strict elimination diet points to food as the driver of the enteropathy. When potential dietary antigens are removed for 6–8 weeks, the gut inflammatory response often settles if a food allergy or intolerance is the underlying cause. A positive response thus supports a diagnosis of food-responsive enteropathy and guides management toward a diet designed to avoid triggering proteins (for example, a hydrolyzed or novel-protein diet) rather than jumping to antimicrobial or immunosuppressive therapies. This dietary approach aims to control symptoms by eliminating the offending dietary antigen, which is distinct from infectious causes (which would not typically resolve with diet alone), autoimmune disease (which usually requires other therapies), or neoplasia (which would not be expected to improve with elimination of dietary antigens). If symptoms improve during the elimination phase but recur on reintroduction, that further confirms the role of diet in driving the disease.
