Levels of uric acid in the blood are lower in adults with Prader-Willi syndrome (PWS) who are obese than in people without PWS but who also are obese, a study shows. Fat-free body mass was the strongest predictor of uric acid levels. Researchers…

High protein meals induce the secretion of the insulin-stimulating hormone glucagon-like peptide 1 (GLP-1) in children with Prader-Willi syndrome (PWS), suggesting that these kinds of meals may help suppress appetite, a pilot study has found.  The study, “…

Growth hormone therapy improves height and body composition while lowering body mass index (BMI) in people with Prader-Willi syndrome (PWS), according to a review of clinical trials. The study, “Growth hormone treatment in Prader-Willi syndrome patients: systematic review…
