What to watch with tTG IgA and Abnehmen?

tTG IgA is a biomarker for celiac disease. Elevated levels indicate active celiac disease, which can cause weight loss due to malabsorption or dietary changes. If you experience unintentional weight loss, celiac testing may be warranted. However, tTG IgA is not a direct marker for weight loss success in a general diet. The provided context lacks specific studies linking tTG IgA to weight loss, so the evidence is unclear. A MyBody-X test for tTG IgA can be part of a celiac screening but should not replace medical diagnosis. Caveats: false positives/negatives can occur, especially with IgA deficiency or prior gluten-free diet.
