This review looked at which patients should be tested for celiac disease, a condition where the immune system reacts to gluten in food. The authors found that celiac disease is often missed and recommend testing in people with certain autoimmune diseases, digestive problems, thyroid disease, and other specific conditions—including chronic fatigue syndrome. They suggest blood tests first, with biopsies during endoscopy if needed to confirm the diagnosis.
This study is important for ME/CFS patients because chronic fatigue syndrome is explicitly identified as a condition warranting celiac disease screening, suggesting a potential overlap or mimicry between these conditions. Undiagnosed celiac disease could contribute to or complicate ME/CFS symptoms, making screening relevant to patient care and treatment optimization. Understanding comorbidity patterns may help clinicians better manage ME/CFS patients with multiple autoimmune or systemic conditions.
This review does not prove that celiac disease causes chronic fatigue syndrome or that all ME/CFS patients have celiac disease. It only identifies an association suggesting CFS patients warrant screening, not that the conditions are causally linked. The study does not establish prevalence rates of celiac disease specifically in ME/CFS populations or demonstrate clinical outcomes following celiac disease diagnosis in fatigued patients.
About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
