Acid reflux is a condition that occurs when stomach juices flow backwards into the esophagus and sometimes into the mouth. Some infants experience this problem, which may also be referred to as gastroesophageal reflux or GERD, due to a condition at birth that may resolve itself within their first year. In adults, acid reflux can be experienced as chronic heartburn, nausea, bloating, burping and chest pain, and may contribute to the development of a pre-cancerous condition known as Barrett’s esophagus. Patients who smoke, are pregnant or overweight, drink alcohol or carbonated beverages, or eat acidic foods such as tomatoes, onions or heavily spiced meals are at greater risk for acid reflux. Treatments available for this condition include medications, lifestyle modifications, and minimally invasive surgical procedures including hiatal hernia repair and Nissen fundoplication.
