This simple procedure
is done to evaluate the actual amount of
gastroesophageal reflux that you may have.
Some people feel like they are having a lot
of reflux, when in fact they are not. Their
symptoms may be from other esophageal problems,
but not reflux. The test consists of small
device which measures the actual pH of your
esophagus over 24 to 48 hours. Two types of
pH devices are available: a long, thin tube
which is passed through your nose into your
esophagus, and a small capsule which is attached
by suction to your esophagus lining. Each test
has its pluses and minuses; your gastroenterologist
will determine which one would give you the
best solution for the cause of your symptoms.
