    GERD and Acid Reflux in Infants and Children

    Most babies spit up sometimes, even several times a day. But when vomiting causes other problems or comes with other symptoms, it may be due to acid reflux, also called gastroesophageal reflux disease (GERD).

    What Are the Symptoms of Acid Reflux in Infants and Children?

    GERD may seem like an adults-only issue, but it can happen to infants and children, too. The most common symptoms in kids are:

    • Vomiting often
    • A cough that won’t go away
    • Refusing to eat or trouble eating (a child may choke or gag)
    • Crying during or after a feeding
    • Heartburn, gas, or belly pain

    What Causes GERD and Acid Reflux in Infants and Children?

    Acid reflux happens when food and acid in the stomach move back up into the tube that goes to the mouth, called the esophagus. Sometimes it moves into or out of the mouth.

    Most infants with the condition are healthy -- it’s just that parts of their digestive systems aren’t fully mature yet. They usually grow out of GERD by the time they are 1 year old.

    In older children, the causes of GERD are different than for infants and adults. In many cases, it happens when the muscular valve between the stomach and esophagus relaxes or when pressure builds up below that valve.

    How Is Acid Reflux Diagnosed?

    Usually, the doctor can diagnose acid reflux based on the symptoms you describe and your child’s medical history, especially if the problem happens regularly and causes discomfort. Sometimes, your child may need more tests, such as:

    • Barium swallow or upper GI series. This is a special X-ray test. Your child will drink a chalky substance to highlight his esophagus, stomach, and upper part of his small intestine. It can show if anything is blocking or narrowing these areas.
    • pH probe. Your child will swallow a long, thin tube with a probe at the tip, which will stay in his esophagus for 24 hours. The tip measures levels of acids in his stomach. If your child has breathing problems, this test also can help the doctor tell if they’re the result of reflux.
    • Upper GI endoscopy. This test uses a thin, flexible, lighted tube and camera that allows the doctor to look directly inside the esophagus, stomach, and upper part of the small intestine.
    • Gastric emptying study. Your child drinks milk or eats food mixed with a radioactive chemical, and a special camera follows it through his digestive tract. It will show if his reflux happens because his stomach empties too slowly.
