Diagnosis often involves a combination of clinical observation and diagnostic tests. These may include:
- Esophageal pH Monitoring: Measures acid levels in the esophagus. - Upper GI Series: X-rays of the esophagus and stomach. - Endoscopy: A camera is used to visualize the esophagus and stomach lining. - Milk Scan: A radioactive tracer is mixed with milk to observe the passage through the digestive system.
