What to watch with HLA-DQ2 and Müdigkeit?

HLA-DQ2 is a strong genetic risk factor for celiac disease, an autoimmune condition triggered by gluten. Fatigue is a common but non-specific symptom of celiac disease, often due to malabsorption, inflammation, or associated deficiencies (e.g., iron, B12). However, not everyone with HLA-DQ2 develops celiac disease; penetrance is low (~2–5%). A positive genetic test alone is not diagnostic. If you experience persistent fatigue, consult a physician for proper evaluation (celiac serology, duodenal biopsy). Also consider other causes like thyroid disorders, sleep issues, or stress. The evidence linking HLA-DQ2 to celiac-related fatigue is human-strong, but the test result is only one piece of the puzzle. Do not change your diet based solely on genetics.
