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
examination 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 (Novo-Cimetine, Nu-Cimet). 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 lansoprazole (Prevacid) and omeprazole (Losec). These medicines usually work
best.
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.
