What to watch with Zöliakie Test and sleep?

A celiac test (e.g., HLA-DQ2/DQ8 or tTG-IgA) is for diagnosing gluten intolerance, not directly for sleep analysis. However, untreated celiac disease can impair sleep due to nutrient deficiencies (iron, vitamin D, B12) or inflammatory processes. After diagnosis and a gluten-free diet, sleep issues often improve. A pure genetic test for celiac (HLA-DQB1) only indicates predisposition, not active disease. For sleep disturbances, also consider stress, caffeine, or sleep hygiene. The evidence for a direct link between celiac genetics and sleep is moderate – clinical symptoms and lab values are key.
