The question about the genetics of weight loss injections (GLP-1 agonists like semaglutide) is relevant, but the scientific evidence is still limited. There are indications that variants in genes such as TCF7L2, associated with diabetes and weight regulation, may influence efficacy. Genes of the reward system (e.g., DRD2, OPRM1) are also discussed. However, effects are generally small and insufficient to recommend personalized therapy. Current guidelines rely on clinical parameters (BMI, metabolic status) rather than genetic tests. Moreover, these injections are prescription-only and have side effects (nausea, pancreatitis). A genetic test cannot currently determine whether to use them. Research is in early stages; larger studies are needed. Bottom line: genetics plays a role but is not yet practice-relevant. Discuss therapy with a physician.
