Gerd is the abbreviation of Gastroesophageal Reflux Disease. Gastroesophageal refers to the stomach and esophagus and Reflux means to flow back or return. All in all, Gerd is a chronic digestive disease where the liquid content of the stomach refluxes into the esophagus.
In normal digestion, the lower esophageal sphincter (LES), the ring of muscle between the esophagus and stomach, opens to allow food to pass into the stomach and closes to prevent food and acidic stomach juices from flowing back into the esophagus. Gastroesophageal reflux occurs when the LES is weak or relaxes inappropriately, allowing the stomach's contents to flow up into the esophagus. The severity of Gerd is decided byLES dysfunction as well as the type and amount of fluid brought up from the stomach and the neutralizing effect of saliva. GERD is a kind of mild acid reflux that may occur twice a week, or moderate to severe acid reflux that may occur once a week. In most cases, Gerd can be relieved through healthier diets and lifestyles; however, some people may need a medication or surgery.
