GERD: A Growing Concern
Excerpt

(HealthScoutNews)
-- Gastroesophageal reflux disease, or GERD, is a chronic condition
that is more common than you might think but missed more often
than you might guess.
Yet, GERD's symptoms are all too
familiar to the 25 million American adults who experience them
on a daily basis: heartburn; an acid taste in your mouth; trouble
swallowing; and regurgitation of food.
Most mild cases are easily treated
with changes in eating habits and medications, and more severe
ones can be treated with the latest in surgical procedures. But
some doctors are starting to make the troubling link between the
increasing number of GERD cases and a similar jump in the number
of cases of esophageal cancer.
GERD occurs when stomach acid makes
its way into the esophagus, usually because the valve that separates
the two relaxes as people age. Alcohol, chocolate, caffeine and
heavy meals can aggravate the condition.
"For most people, GERD is
a lifestyle issue," says Dr. Garth Ballantine, a New Jersey
surgeon who treats those with serious GERD. "If you're like
me and have steak and red wine for dinner and maybe a cigar and
glass of port afterwards, well, anyone who has that meal is going
to have reflux. And I can choose not to have reflux by avoiding
those foods."
However, those whose symptoms are
more constant and more severe need to get treatment before more
serious conditions develop.
That's part of the reason why the
fourth annual GERD Awareness Week starts today, supported by the
International Foundation for Functional Gastrointestinal Disorders
(IFFGD).
"GERD, of which heartburn
is the most common symptom, is pretty common among adults,"
says Dr. Timothy Wang, head of gastroenterology at the University
of Massachusetts School of Medicine. "And the major concern
is that esophageal cancer is the fastest-rising cancer in the
United States -- up 8 percent a year -- and a presumption is that
the rise is related to GERD."
"But while there is a lot
of research on GERD, there aren't a lot of answers," Wang
adds. "So we are treating GERD more aggressively, but don't
want to over-alarm people, as those at risk for cancer are a pretty
small group, only about 1 percent."
That group includes those with
a condition called Barrett's esophagus, which occurs when chronic
GERD has changed the cellular makeup of the lining of the esophagus,
Wang says. When that happens, those people face a higher risk
of esophageal cancer.
Esophageal cancer strikes men three
times more often than women, according to the American Cancer
Society. It's not a common cancer -- roughly 13,100 new esophageal
cancer cases will be diagnosed in 2002, according to estimates.
That compares to 131,600 new cases of colon cancer.
Although people with Barrett's
esophagus need to be monitored regularly, Wang says, the majority
of people with GERD can turn to simpler treatments to control
their discomfort.
"The usual numbers are that
40 percent of the adult population get heartburn once a month,
7 percent once a week and 3 percent once a day. And 98 percent
of these symptoms are controlled by lifestyle changes or over-the-counter
medicines," Ballantine says.
To relieve symptoms, people can
take antacids, which eases heartburn by neutralizing the acid
in the esophagus. For chronic reflux, he says, doctors prescribe
stronger medicines, including Pepcid and Tagamet, and proton pump
inhibitors such as Prilosec.
For approximately 2 percent of
people, however, medication doesn't help. Doctors then have to
check for a hiatal hernia -- when part of the stomach moves up
into the chest. They can also assess the acid levels in the esophagus
and look at the lining of the esophagus through a small camera,
a procedure called an endoscopy, Wang says.
The procedure can find inflammation,
ulcers or the cellular changes in the esophageal lining that signal
Barrett's esophagus, Wang says, "but most peoples' esophageal
linings look normal."
If doctors do find that chronic
GERD is too uncomfortable or dangerous to a person's health, there
are some surgical procedures that can tighten the valve that controls
the amount of acid that leaks into the esophagus.
The U.S. Food and Drug Administration
(FDA) recently approved two minimally invasive surgeries for GERD
that can be done on an outpatient basis. One procedure uses a
tube with a tiny device on the end that can stitch and tighten
the valve, and the other uses a catheter with needle electrodes
that use radio waves to tighten the valve. However, Ballantine
and Wang say early results on both of these procedures are mixed.
As a last resort, Ballantine says,
patients can have laparoscopic surgery that can correct a hiatal
hernia or tighten the stomach around the bottom of the esophagus.
Better yet, he says, you can stop
GERD before it leads to problems.
"Most people can choose among
certain lifestyle changes that will or will not prompt reflux,"
he says.
