Reflux in infants is often diagnosed based on the baby’s symptoms and a physical examination by a healthcare provider. In some cases, additional tests may be required to confirm the diagnosis or rule out other conditions. These tests can include:
- Upper GI Series: An X-ray exam to visualize the esophagus, stomach, and upper part of the small intestine.
- pH Probe: A test that measures the acidity in the esophagus over a 24-hour period.
- Endoscopy: A procedure where a small camera is used to examine the esophagus and stomach lining.
