What it means
Acid reflux occurs when stomach acid repeatedly flows back up into the esophagus, causing symptoms such as heartburn, regurgitation of sour liquid, chest discomfort, hoarseness, chronic cough, or a sensation of a lump in the throat. When acid reflux happens frequently and causes complications, the condition is called gastroesophageal reflux disease, or GERD. Risk factors include obesity, smoking, pregnancy, hiatal hernia, and certain medications. Lifestyle changes such as losing weight, avoiding trigger foods, eating smaller meals, and not lying down right after eating can help. Untreated GERD can damage the esophagus over time.
