The goal of this clinical trial is to evaluate whether two types of breathing training can improve symptoms of gastroesophageal reflux disease (GERD) in adults. The main research questions are: * Do volume-oriented incentive spirometry (VIS) or diaphragmatic breathing exercise (DBE) improve GERD symptoms compared with usual care? * Do these breathing exercises reduce the symptoms of GERD? * Does volume-oriented incentive spirometry (VIS) produce greater improvement in GERD symptoms compared with DBE? * Do these exercises increase the strength of the lower esophageal sphincter (LES)? Researchers will compare VIS training, DBE training, and usual care to determine whether breathing training can serve as a safe and effective non-pharmacological treatment option for GERD. Participants will: * Be randomly assigned to VIS training, DBE training, or usual care * Perform their assigned breathing training (if in the intervention group) twice daily for 6 weeks * Attend study visits at baseline and at week 7 for questionnaires and esophageal function tests * Keep a diary of their symptoms and breathing practice
