RefluxG is a medical device used to treat symptoms related to gastro-oesophageal reflux. Gastro-oesophageal reflux is quite a frequent disorder manifested by resurgence of gastric juices along the oesophagus. The gastric contents, given their acidity, may cause the irritation of the oesophageal mucosa and typical symptoms and lesions such as reflux oesophagitis, acid reflux, heartburn, burning, pain in the upper and middle abdomen, and irritative cough. When reflux is too frequent (at least once a week) or when the gastric contents are excessively acidic, the disorder becomes pathological. which is thus described as gastroesophageal reflux disease (GERD).
