When talking about Gastro-Oesophageal Reflux (GERD) mean reflux of gastric contents into the esophagus. When reflux causes severe symptoms-complications and problems in our quality of life by gastric acid reflux then talk about Gastro-Esophageal Reflux Disease (GERD).
The esophagus is a straight tube which serves to transfer food from the mouth to the stomach. In the lower part there is an anatomical region, called the lower esophageal sphincter (LES), which is an excellent valve mechanism. Specifically, the LES allows the passage of food from the esophagus to the stomach only when swallowed, while at other times prevents reflux of gastric contents into the esophagus.
The GERD occurs when transient relaxation of (CEC) or when the LES is not sufficiently close.
When acid reflux occurs we feel the food or liquid to the back of the oral cavity. Moreover, when the acidic contents of the stomach contacts the esophageal mucosa appears heartburn (heartburn-burning behind the breastbone).
Regardless of the above, it should be noted that transient reflux episodes during the 24 hours are normal and are not necessarily GERD, but when it is often possible to cause many problems
