Gastroesophageal reflux (GERD)
Your child's physician will perform a physical examination and obtain a medical history. Diagnostic procedures that may be done include:
- A chest x-ray, to look for evidence of aspiration or pneumonia
- An upper gastrointestinal series, which examines the organs of the upper part of the digestive system; your child will swallow a fluid called barium-a chalky liquid used to coat the insides of the esophagus, stomach, and the first section of the small intestine so that they can be seen in an x-ray.
- An endoscopy, a test that uses a small, flexible tube with a light and a camera at the end to examine the inside of the digestive tract.
- Ph Testing, in which a small tube is passed into the esophagus to measure the pH, or acid level therein, over 12 to 24 hours
Gastric emptying studies, which measure the speed at which the food empties from the stomach. Watch a Gastric Emptying Study Movie.
