In GERD, the valve at the top of the stomach (where the stomach and the
esophagus connect) does not close tightly enough. This allows the contents of
the stomach to move up into the esophagus.
GERD usually causes a
feeling of burning, warmth, heat, or pain that often starts in the upper part
of your belly, just below your breastbone (sternum). This feeling (called
heartburn) may spread in waves upward into your throat, and you may have a sour
taste in your mouth. Heartburn is sometimes called indigestion, acid
regurgitation, sour stomach, or pyrosis.
