Tests healthcare providers use to diagnose GERD
It may be possible for your healthcare provider to diagnose GERD (acid reflux disease) based just on a physical examination and the information you provide. That is why it is so important to
talk with the healthcare provider about all your child's symptoms. Sometimes, diagnostic tests may also be needed. These tests can check your child's esophagus, stomach, and small intestine to see if there are problems.
- Barium swallow radiograph (also called an upper GI series) — The child is given a small amount of special liquid to drink, and then x-rays are taken. The liquid allows the healthcare provider to see the outline of the esophagus, stomach, and upper part of the small intestine. The upper GI series can help spot problems with the shape or size of the esophagus. However, this test cannot be used on its own to diagnose GERD.
- Endoscopy — This test looks for damage to the esophagus that may be caused by stomach acid. Your child receives anesthesia (medicine that puts him or her to sleep for a short time). The healthcare provider slides a thin, flexible plastic tube down into the child's esophagus. A tiny camera on the end of the tube allows the healthcare provider to look closely at the lining of the esophagus, stomach, and small intestine to check for any signs of damage from the stomach acid or other problems. This test can be used to diagnose GERD.
- Esophageal pH monitoring — This test measures the acid levels in the esophagus and shows when acid reflux occurs. One common pH monitoring test is called a pH probe. The healthcare provider places a thin flexible tube through a child's nose down into the esophagus with the tip just above the stomach. The other end of the tube (the probe) is connected to a recording device that monitors the acid levels. The tube stays in for about 24 hours. This test helps to diagnose GERD but cannot tell whether the esophagus has been damaged.
When testing is finished, your healthcare provider may be able to tell if your child's symptoms are GERD. If they are, treatment is available that can relieve the symptoms
and heal damage (called
erosions) to the esophagus. Ask your healthcare provider whether Prevacid is right for your child.
