Gastroesophageal Reflux in Babies and Children

Topic Overview

What is gastroesophageal reflux?

Gastroesophageal reflux happens when food and stomach acid flow from the stomach back into the esophagus. The esophagus is the tube that carries food from the mouth to the stomach. In adults, reflux is often called heartburn or acid reflux.

Reflux is common in babies and children, and it is usually not a sign of a serious problem. Most babies stop having reflux around 1 year of age. A child who continues to have reflux may need treatment.

What causes reflux?

Reflux happens because of a problem with the ring of muscle at the end of the esophagus called the lower esophageal sphincter, or LES. The LES acts like a one-way valve between the esophagus and the stomach. When you swallow, it lets food pass into the stomach. If the LES is weak, stomach contents can flow back up into the esophagus.

In babies, this problem happens because the digestive tract is still growing. Reflux usually goes away as a baby matures.

What are the symptoms?

It is common for babies to spit up after they eat. Babies with reflux may spit up more forcefully. Babies with severe reflux may cry, act fussy, or have trouble eating. They may not sleep well or grow as expected.

Older children and teens may have the same symptoms as adults. They may cough a lot and have a burning feeling in their chest and throat (heartburn). They may have a sour or bitter taste in their mouth.

If stomach acid goes up to the throat or into the airways, a child may get hoarse or have a lasting cough. Reflux can also cause pneumonia or wheezing, and it may hurt to swallow.

How is reflux diagnosed?

To find out if a child has reflux, a doctor will do a physical exam and ask about symptoms. A baby who is healthy and growing may not need any tests. If a teen is having symptoms, the doctor may want to see if medicines help before doing tests.

If a baby is not growing as expected or treatment doesn't help a teen, the doctor may want to do tests to help find the cause of the problem. Common tests include:

• A barium swallow, which is a series of X-rays that shows the esophagus and stomach.
• Endoscopy, which lets the doctor look at the esophagus.
• An esophageal pH test, which measures how much acid is in the esophagus.

How is it treated?

Most babies stop having reflux over time, so the doctor may just suggest that you follow some steps to help reduce the problem until it goes away. For example, it may help to:

• Burp the baby a few times during each feeding.
• Keep the baby upright for 30 minutes after each feeding.
• Avoid feeding too much at one time. Give the baby smaller meals more often.

For older children and teens, it may help to:

• Raise the head of the child’s bed 6 to 8 inches.
• Have the child stay upright for 2 to 3 hours after eating.
• Serve 5 or 6 small meals instead of 2 or 3 big ones.
• Limit foods that might make reflux worse. These include chocolate, sodas that have caffeine, spicy foods, fried foods, and high-acid foods such as oranges and tomatoes.

If these steps don't work, the doctor may suggest medicine. Medicines that may be used include:

• Antacids, such as Mylanta and Maalox. Antacids neutralize stomach acid and relieve heartburn. You can buy these without a prescription.
• H2 blockers, such as ranitidine (Zantac) and cimetidine (Tagamet). H2 blockers reduce the amount of acid in the stomach. You can buy some of these without a prescription. For stronger doses, you will need a prescription.
• Proton pump inhibitors, such as esomeprazole (Nexium) and omeprazole (Prilosec). These medicines usually work best. You can buy some proton pump inhibitors without a prescription. But talk to your doctor before you give these medicines to your child.

Before you give your child any over-the-counter medicine:

• Read the label. Do not give a child any product that contains bismuth subsalicylate, such as Pepto-Bismol or Kaopectate. Experts think it may be linked to Reye's syndrome, a rare but serious illness.
• Be sure you understand how much and how often to give the medicine to your child. If you are not sure, ask your doctor.

Children with reflux rarely need surgery. It may be an option for babies or children who have severe reflux that causes breathing problems or keeps them from growing.
