Myths vs facts: Zöliakie Test and Abnehmen

A celiac test (tissue transglutaminase IgA) is a valid diagnostic tool for celiac disease, an autoimmune enteropathy. The test itself does not cause weight loss. However, some individuals with undiagnosed celiac disease experience weight loss or failure to thrive due to malabsorption. After diagnosis and a gluten-free diet, weight often normalizes – but may also increase if prior malabsorption existed. Myths: The test indicates a 'gluten sensitivity' that automatically leads to weight loss. Facts: Without celiac disease, a gluten-free diet has no proven effect on body weight. Moreover, self-testing without medical confirmation is risky because starting a gluten-free diet before testing can skew results. Evidence: Diagnostic accuracy is human-strong (guidelines), but weight loss claims are marketing-driven. Caveat: No guarantee of weight loss; consult a physician if celiac is suspected.
