Long-term semaglutide treatment (0.5–2 mg weekly) induces significant weight loss (up to 14.4%) and appetite suppression in Prader-Willi syndrome (PWS) patients without diabetes, though efficacy is variable and weight regain occurs upon discontinuation.

For PWS patients, semaglutide (0.5-2mg weekly) is a viable option for weight loss and appetite control, even after bariatric surgery. However, results vary, and stopping the drug leads to weight regain. It should be used as a long-term maintenance therapy alongside strict dietary controls, not as a one-time fix.
