Gastroesphageal
Reflux (GERD)
What is GERD?
Gastroesophageal
reflux disease, or GERD, occurs when acid from the stomach backs up
into the esophagus. Normally, food travels from the mouth, down
through the esophagus and into the stomach. A ring of muscle at the
bottom of the esophagus, the lower esophageal sphincter (LES),
contracts to keep the acidic contents of the stomach from “refluxing”
or coming back up into the esophagus. In those who have GERD, the LES
does not close properly, allowing acid to move up the esophagus.
When stomach acid
touches the sensitive tissue lining the esophagus, it causes a
reaction similar to squirting lemon juice in your eye. This is why
GERD is often characterized by the burning sensation known as
heartburn.
Occasional heartburn
is normal. However, if heartburn becomes chronic, occurring more than
twice a week, you may have GERD. Left untreated, GERD can lead to more
serious health problems.
Who gets GERD?
Anyone can have GERD.
Women, men, infants and children can all experience this disorder.
Overweight people and pregnant women are particularly susceptible
because of the pressure on their stomachs. Recent studies indicate
that GERD may often be overlooked in infants and children. In infants
and children, GERD can cause repeated vomiting, coughing, and other
respiratory problems such as sore throat and ear infections. Most
infants grow out of GERD by the time they are one year old.
Tips to Prevent GERD
What are the
symptoms of GERD?
The symptoms of GERD
may include persistent heartburn, acid regurgitation, and nausea. Some
people have GERD without heartburn. Instead, they experience pain in
the chest that can be sever enough to mimic the pain of a heart
attack, hoarseness in the morning, or trouble swallowing. Some people
may also feel like they have food stuck in their throat or like they
are choking. GERD can also cause a dry cough and bad breath.
What are the complications of GERD?
GERD can lead to
other medical problems such as ulcers and strictures of the esophagus
(esophagitis), cough, asthma, throat and laryngeal inflammation,
inflammation and infection of the lungs, and collection of fluid in
the sinuses and middle ear. GERD can also cause a change in the
esophageal lining called Barrett's esophagus, which is a serious
complication that can lead to cancer.
What causes GERD?
Physical causes of
GERD can include: a malfunctioning or abnormal lower esophageal
sphincter muscle (LES), hiatal hernia, abnormal esophageal
contractions, and slow emptying of the stomach.
Lifestyle factors
that contribute to GERD include:
-
alcohol use
-
obesity
-
pregnancy
-
smoking
-
Certain foods can
contribute to GERD, such as:
-
citrus fruits
-
chocolate
-
caffeinated drinks
-
fatty and fried
foods
-
garlic and onions
-
mint flavorings
(especially peppermint)
-
spicy foods
-
tomato-based foods,
like spaghetti sauce, chili, and pizza
When should I see a doctor?
If you experience
heartburn more than twice a week, frequent chest pains after eating,
trouble swallowing, persistent nausea, and cough or sore throat
unrelated to illness, you may have GERD. For proper diagnosis and
treatment, you should be evaluated by a physician.
How can my ENT help?
Otolaryngologists, or
ear, nose, and throat doctors, and have extensive experience with the
tools that diagnose GERD and they are specialists in the treatment of
many of the complications of GERD, including: sinus and ear
infections, throat and laryngeal inflammation, Barrett’s esophagus,
and ulcerations of the esophagus.
How is GERD diagnosed?
GERD can be diagnosed
or evaluated by clinical observation and the patient’s response to a
trial of treatment with medication. In some cases other tests may be
needed including: an endoscopic examination (a long tube with a camera
inserted into the esophagus), biopsy, x-ray, examination of the throat
and larynx, 24 hour esophageal acid testing, esophageal motility
testing (manometry), emptying studies of the stomach, and esophageal
acid perfusion (Bernstein test). Endoscopic examination, biopsy, and
x-ray may be performed as an outpatient in a hospital setting. Light
sedation may be used for endoscopic examinations.
While most people
with GERD respond to a combination of lifestyle changes and
medication. Occasionally, surgery is recommended.
Lifestyle changes
include: losing weight, quitting smoking, wearing loose clothing
around the waist, raising the head of your bed (so gravity can help
keep stomach acid in the stomach), eating your last meal of the day
three hours before bed, and limiting certain foods such as spicy and
high fat foods, caffeine, alcohol,.
Medications your
doctor may prescribe for GERD include: antacids (such as Tums,
Rolaids, etc.), histamine antagonists (H2 blockers such as Tagamet,),
proton pump inhibitors (such as Prilosec, Prevacid, Aciphex, Protonix,
and Nexium), pro-motility drugs (Reglan), and foam barriers
(Gaviscon). Some of these products are now available over-the-counter
and do not require a prescription.
Surgical treatment
includes: fundoplication, a procedure where a part of the stomach is
wrapped around the lower esophagus to tighten the LES, and endoscopy,
where hand stitches or a laser is used to make the LES tighter.
Are there long-term health problems
associated with GERD?
GERD may damage the
lining of the esophagus, thereby causing inflammation (esophagitis),
although usually it does not. Barrett's esophagus is a pre-cancerous
condition that requires periodic endoscopic surveillance for the
development of cancer.
