Gastroesophageal Reflux Disease (GERD)/Heartburn
What is GERD?
GERD (gastroesophageal reflux disease) is a digestive disorder. It's caused when gastric
acid from your stomach flows back up into your food pipe (esophagus).
Heartburn is the most common symptom of GERD.
What causes GERD?
GERD happens when gastric acid from your stomach backs up into your food pipe (esophagus).
A muscle at the bottom of the esophagus opens to let food in. And it closes to keep
food in the stomach. This muscle is called the lower esophageal sphincter (LES). When
your LES relaxes too often or for too long, acid backs up into your esophagus. This
causes heartburn and may cause damage.
Some lifestyle issues that can cause GERD may include:
Eating foods such as citrus, chocolate, and fatty or spicy foods
Using aspirin and over-the-counter pain and fever medicines. These include nonsteroidal
anti-inflammatory drugs (NSAIDs) such as ibuprofen and naproxen.
Some health problems that may cause heartburn may include:
Swelling of your stomach lining (gastritis)
Painful sores (ulcers) on the lining of your stomach or esophagus, or the first part
of your small intestine (duodenum)
An allergic condition in the esophagus (eosinophilic esophagitis)
Who is at risk for GERD?
You may be more at risk for GERD if you:
Have a part of your stomach slide up out of the belly cavity next to your esophagus
Have a weak lower esophageal sphincter or LES
Use some medicines, such as aspirin or over-the-counter pain and fever medicines such
Smoke or are around secondhand smoke
What are the symptoms of GERD?
Heartburn, also called acid indigestion, or acid reflux, is the most common symptom
of GERD. Heartburn is a burning chest pain that starts behind your breastbone and
moves up to your neck and throat. It can last as long as 2 hours. It often feels worse
after you eat. Lying down or bending over can also cause heartburn. Another common
symptom of GERD is bringing swallowed food up again to the mouth (regurgitation).
Some people can have trouble swallowing.
Heartburn is not a GERD symptom for most children younger than 12 years old, and for
some adults. They may have a dry cough, asthma symptoms, or trouble swallowing instead.
Each person’s symptoms may vary. GERD symptoms may seem like other health problems.
Always see your healthcare provider to be sure.
How is GERD diagnosed?
To see if you have GERD, your healthcare provider will give you a physical exam and
ask about your past health. Some people with typical symptoms may be treated without
Other tests for GERD may include:
Upper GI (gastrointestinal) series, also called a barium swallow. This test looks at the organs of the top part of your digestive system. It checks
your food pipe (esophagus), stomach, and the first part of your small intestine (duodenum).
You will swallow a metallic fluid called barium. Barium coats the organs so that they
can be seen on an X-ray.
Upper endoscopy or EGD (esophagogastroduodenoscopy). This test looks at the lining or inside of your esophagus, stomach, and duodenum.
This test uses a thin, lighted tube (endoscope). The tube has a camera at one end.
The tube is put into your mouth and throat. Then it goes into your esophagus, stomach,
and duodenum. Your healthcare provider can see the inside of these organs. He or she
can also take a small tissue sample (biopsy) if needed.
Bernstein test. This test helps to see if your symptoms are caused by acid in your esophagus. The
test is done by dripping a mild acid through a tube placed in your esophagus.
Esophageal manometry. This test checks the strength of your esophagus muscles. It can see if you have any
problems with backward flow of fluid (reflux) or swallowing. A small tube is put into
your nostril, then down your throat and into your esophagus. The tube checks how much
pressure your esophageal muscles make when they are at rest.
pH monitoring. This test checks the pH (acid level) in your esophagus. A thin, plastic tube is placed
into your nostril, down your throat, and into your esophagus. The tube has a sensor
that measures pH level. The other end of the tube outside your body is attached to
a small monitor that records your pH levels for 24 to 48 hours. During this time you
can go home and do your normal activities. You will need to keep a diary of any symptoms
you feel, and also of the food you eat. Your pH readings are checked and compared
to your activity for that time period.
Impedance testing. This test is able to see reflux of acid, plus nonacid liquid and air. It is combined
with pH monitoring.
How is GERD treated?
Treatment will depend on your child’s symptoms, age, and general health. It will also
depend on how severe the condition is.
In many cases making diet and lifestyle changes can help reduce GERD symptoms. Always
check with your healthcare provider before making any changes.
If you have GERD, be careful about what you eat and drink. Don’t have too much of
You should also:
Eat smaller amounts
Not drink too much alcohol
Wait a few hours after eating before you lie down or go to bed
Lose weight if needed
Raise the head of your bed 6 inches (to do this, put bricks, cinderblocks, or bedrisers
under the bed legs at the head of the bed)
Check any medicines you are taking. Some may cause problems with the lining of your
stomach or esophagus. You may also want to talk with your healthcare provider about:
Taking medicines to reduce your stomach acid (antacids)
Taking medicines called H2-blockers and proton pump inhibitors. Taking these medicines
before eating may stop heartburn from happening.
Taking medicines that help to empty food from your stomach (promotility medicines).
You will need a prescription for these. But these medicines are rarely used to treat
reflux disease unless there are other problems, too.
Having surgery called fundoplication. This is sometimes done to help keep the esophagus
in the right place and to stop the backward flow of fluid (reflux).
What are possible complications of GERD?
If GERD is not treated, it can lead to other health problems. These may include:
Esophagitis. This is an irritation of the esophagus caused by the acid in your stomach contents.
Narrowing of the esophagus, also called strictures. This can make it hard to swallow.
Breathing problems. This happens when stomach contents from your esophagus go into your lungs.
Barrett’s esophagus. This affects the lining of your esophagus. In some cases it can lead to esophageal
What can I do to prevent GERD?
Some of the same diet and lifestyle changes that are used to treat GERD can also help
to prevent it.
Living with GERD
Your healthcare provider will give you advice on how to manage your GERD symptoms.
In most cases you will need to make some diet and lifestyle changes so that GERD pain
won’t get in the way of your normal activities.
When should I call my healthcare provider?
Call your healthcare provider if:
Your GERD symptoms don’t get better with treatment, or they get worse
You have new symptoms
You start vomiting
You have involuntary weight loss
You have trouble or pain with swallowing
You have blood in your vomit or stool
