Acid reflux is scientifically known as Gastroesophageal Reflux Disease (GERD). It is a disease characterized by the abnormal reflux of gastric contents into the esophagus resulting to chronic symptoms or mucosal damage.
Acid reflux is often caused by temporary or permanent alterations in the lining that separates the esophagus and the stomach. Ineffectiveness of the lower esophageal sphincter (LES) or a temporary LES relaxation connected with a hiatal hernia are just some of the common causes of acid reflux. The process can also lead to a backflow of gastric juices to the pharynx or mouth.
Among adults, the most common symptom of acid reflux is heartburn which is caused by the presence of acid in the esophagus. Heartburn is characterized by a painful burning sensation behind the sternum or breastbone. Another symptom or manifestation of acid reflux is esophagitis which is characterized by an inflammation of the lining of the esophagus which is also known as the mucosal lining. Esophagitis also causes swallowing difficulties and chronic pains in the chest area.
Sometimes, individuals suffering from acid reflux may also experience coughing, persistent pain in the ears, hoarseness or a change in the voice and even sinusitis. If acid reflux gets complicated it may lead to formation of a stricture or ulcers in the esophagus. It may also lead to a condition called Barrett’s esophagus and in worst cases to cancer of the esophagus.
It doesn’t mean however that a person who regularly suffers from heartburn is suffering from acid reflux. By all means, the heartburn may be from other causes. But if a person suffers from heartburn for more than once a week, then he or she is at a risk of acquiring acid reflux. Person with hiatal hernia are also at a greater risk in developing acid reflux than those who are not.
