was kosten abnehmspritzen — can a DNA test help?

The cost of weight loss injections (GLP-1 agonists like semaglutide, liraglutide) varies widely – typically €100–400 per month depending on the drug, dosage, and country. In Germany, health insurance rarely covers them except for severe obesity with comorbidities. Can a DNA test help? Only to a very limited extent. Weight regulation genetics is highly polygenic; single variants like rs2229616 in the LEPR gene (leptin receptor) have a very low frequency in Europeans (~0.7 %) and explain a tiny fraction of body weight. Evidence for using DNA tests to predict response to GLP-1 agonists is weak – no validated clinical algorithms exist. Most commercial tests rely on association studies with small effect sizes and are more marketing than medicine. More useful are biomarkers such as fasting insulin, HbA1c, or liver enzymes. A DNA test cannot tell you whether the injection will work for you or whether the cost is justified. Decisions should be made with a physician based on metabolic parameters, not a SNP profile.
