What to watch with HLA-DQ2 and Abnehmen?

HLA-DQ2 is a genetic risk marker for celiac disease, an autoimmune condition that can cause intestinal damage and malabsorption when gluten is consumed. Unintentional weight loss is a possible symptom of active celiac disease, but not all carriers experience it. Crucially, only about 1 % of HLA-DQ2 carriers develop celiac disease; the genotype alone is not diagnostic. Any weight loss should be medically evaluated (antibody test, duodenal biopsy) before starting a gluten-free diet. Conversely, gluten-free diets are often promoted for weight loss, but evidence is weak – many gluten-free products are higher in calories. For those with celiac disease, the diet can normalize weight. For non-celiac individuals, HLA-DQ2 is not a relevant factor for weight management; genetics play a minor role compared to calorie balance, exercise, and lifestyle. Caveat: consumer genetic tests often overstate the impact of single variants. Sound nutritional advice should be based on symptoms, lab results, and clinical diagnosis, not solely on a genetic risk marker.
