Weight Loss of Over 100 lbs in a Patient of Prader-Willi Syndrome Treated With Glucagon-Like Peptide-1 (GLP-1) Agonists.

Prader-Willi syndrome (PWS) is the most common genetic obesity syndrome. The clinical features of this condition include childhood obesity, hyperphagia, infantile hypotonia, hypogonadism, short stature, and characteristic facial features. The leading cause of morbidity and mortality in PWS is hyperphagia and resultant obesity. Here, we highlight the effectiveness of glucagon-like peptide-1 (GLP-1) agonists by reporting an interesting case of successful rapid weight loss in an adult with PWS using GLP-1 agonists - exenatide and liraglutide. To the best of our knowledge, this report presents the first clinical evidence supporting the use of GLP-1 receptor agonists in the treatment of genetic obesity syndromes; our patient lost a total of 125 lbs on GLP-1 analog and continues to lose weight.
