Gastroesophageal reflux disease (GERD) is a chronic digestive disorder that occurs when stomach acid or bile flows back into the esophagus, irritating its lining. This backwash, known as acid reflux, can cause discomfort and may lead to more serious complications if left untreated. Common symptoms of GERD include heartburn, regurgitation, difficulty swallowing, chest pain, and a sensation of a lump in the throat.
Several factors can contribute to the development of acid reflux, such as obesity, pregnancy, smoking, certain medications, and a hiatal hernia. Treatment options for acid reflux may include lifestyle changes, over-the-counter or prescription medications, and in severe cases, surgery. The following articles provide more detailed information on the causes, symptoms, diagnosis, and treatment options for reflux.
