Pathophysiology of
GERD
- Gastroesophageal reflux (GER) occurs when stomach
acid or bile flows into the esophagus, leading to the
,
development of esophagitis. Gastroesophageal reflux
disease (GERD) is diagnosed when GER is chronic,
more severe, and causes complications over time.
GERD is caused by abnormalities in
,
the lower esophageal sphincter function, esophageal
motility, or gastric emptying.
Lower Esophageal Sphincter Function
- Normally, the lower esophageal sphincter is a
one-way valve that keeps gastric contents
from coming up into the esophagus. However,
decreased tone of the lower esophageal
sphincter allows acidic stomach contents to
regurgitate into the esophagus.
Esophageal Motility
- Abnormalities in esophageal motility can
disrupt the coordinated contractions that
propel food downward into the stomach.
Disruption of coordinated contractions can
cause delayed gastric emptying.
Delayed Gastric Emptying
- Delayed gastric emptying contributes to
esophagitis by extending the period during
which reflux can occur and increasing the acid
content of chyme.

GERD
