Spit test may spot reflux risk after gastric sleeve surgery

This study looks at whether measuring bile acids and pepsin in saliva can help identify people who develop acid reflux or esophageal damage after sleeve gastrectomy (a type of weight-loss surgery). About 60 adults will give saliva samples before surgery and again 1 and 3 years after, along with routine check-ups and questionnaires. The goal is to see if these saliva tests could become a simple way to predict who needs follow-up care.
