GERD
Almost 30 to 40% of the population experiences
occasional heartburn. Many believe that these are
just bothersome symptoms.
But frequent heartburn may indicate a disease
called GERD, Gastro Esophageal Reflux Disease.
The gastro intestinal system includes: esophagus,
the lower esophageal sphincter, stomach containing
gastric juice, pyloric sphincter, and duodenum.
The food swallowed enters through the esophagus
into the stomach where it is digested by acid
secretions present in the gastric juices.
The lower esophageal sphincter prevents the return
of the gastric juice back to the esophagus.
Abnormal functioning of lower esophageal sphincter
causes GERD. This results in backflow of the
gastric contents to the esophagus and damages it.
Symptoms of GERD are
* Heartburn
* Regurgitation
* Feeling of lump in throat.
