What's GERD?

Frequent acid reflux is known as gastroesophageal reflux disease (GERD).

Heartburn is the most common symptom of GERD, but some people have other symptoms as well, including the following:

• Nighttime heartburn
• Cough
• Sore throat
• Nausea/vomiting
• Trouble swallowing
• Feeling that food is "stuck" in the esophagus
• Acid taste in mouth
• Laryngitis
• Difficulty breathing (asthma-like symptoms)
• Belching

Untreated, GERD may lead to serious complications.
