Researchers want to understand why some people lose a lot of weight after bariatric surgery while others don't have as much success. This study collects a saliva sample and health information from nearly 7,000 people who have had weight loss surgery across Spain. By analyzing genetic and other health factors, the researchers hope to develop a way to predict before surgery which patients will have the best results.
About 30% of people who have bariatric surgery don't get the weight loss results they hoped for. By identifying genetic and health markers that predict success, doctors could eventually personalize surgery recommendations and help more patients achieve their weight loss goals.
