Evidence check: HLA-DQ2 in the context of Stress

HLA-DQ2 is a genetic marker strongly associated with celiac disease. In your MyBody-X report, this marker may be analyzed to assess genetic predisposition for gluten intolerance. The link to stress is indirect: in individuals with celiac disease or non-celiac gluten sensitivity, gluten ingestion can trigger inflammatory responses that may exacerbate stress symptoms such as fatigue, irritability, or brain fog. However, there is no robust evidence that HLA-DQ2 directly influences stress reactivity or resilience. The effect is mechanistic, mediated through immune pathways. A positive result does not mean you will definitely develop celiac disease or handle stress poorly. Clinical utility is limited to evaluating gluten sensitivity. For stress management, lifestyle factors like sleep, exercise, and mindfulness are far more impactful. Evidence: mechanistic, based on immunological associations, not direct stress studies.
