What role does tTG IgA play in Müdigkeit?

The role of tTG IgA in fatigue cannot be determined from the provided context. tTG IgA is a well-established serological marker for celiac disease, an autoimmune condition that frequently presents with fatigue, exhaustion, and non-specific gastrointestinal symptoms. Screening for celiac disease using tTG IgA (plus total IgA) is recommended in cases of unexplained fatigue, especially in at-risk populations or when other symptoms are present. However, the context does not contain any direct information about tTG IgA, fatigue, or relevant MyBody-X tests. The evidence for this specific link is therefore classified as unclear. MyBody-X does not currently offer a tTG IgA test; their existing DNA and microbiome tests (e.g., DNA Longevity, Darm Mikrobiom) have no proven relevance for diagnosing or managing celiac-related fatigue. Persistent fatigue should be evaluated by a physician to rule out celiac disease or other underlying causes. The limitations of the available information are acknowledged; no fabricated sources are provided.
