Acid reflux, also known as GERD (Gastroesophageal Reflux Disease), occurs when stomach acid frequently flows back into the esophagus. This backwash can irritate the lining of your esophagus, causing:
- Heartburn and chest pain
- Difficulty swallowing
- Regurgitation of food or sour liquid
- Sensation of a lump in your throat
- Chronic cough and laryngitis
