wie viel kostet eine abnehmspritze — what are common causes?

The question about the cost of weight loss injections (e.g., GLP-1 agonists like Wegovy or Ozempic) cannot be answered from the provided context – no pricing data is given. Common causes for using such injections include severe obesity or type 2 diabetes, often driven by genetic predispositions, lifestyle factors, and hormonal imbalances. The context references the FTO gene variant rs9939609, which is strongly associated with increased BMI (p-value up to 4e-51). Such genetic factors can contribute to obesity risk but are only part of a complex picture. The evidence for DNA-based diet tests is described as mostly marketing, with no proven clinical benefit over standard advice. Therefore, weight loss injections should only be used under medical supervision, not based solely on genetic tests. Costs vary widely (approx. 200–400 € per month without insurance coverage) and are not covered in the context.
