Gastroesophageal reflux disease (GERD) is a common condition in which stomach acid flows back up into the esophagus (food pipe).

GERD is caused by a weakened or relaxed lower esophageal sphincter (LES).

The most common symptom of GERD is heartburn

Heartburn is a burning sensation in the chest that can move up to the neck and throat.

GERD is usually diagnosed based on a patient's symptoms and medical history.

Treatment for GERD typically involves a combination of lifestyle changes and medications.

In some cases, surgery may be recommended for GERD that does not respond to lifestyle changes and medications.

GERD is a common condition that can cause a variety of symptoms.

If you think you may have GERD, it is important to see a doctor to get diagnosed and treated.
