Acid reflux

Acid reflux is when stomach acid travels back up from your stomach to your esophagus, often causing heartburn. Gastroesophageal reflux disease (GERD) is a severe form of acid reflux.

Signs and symptoms

 * an unpleasant sour taste in your mouth (caused by stomach acid)

Some people also have:
 * a cough or hiccups that keep coming back
 * a hoarse voice

Symptoms are often worse after eating, when lying down, and when bending over.
