The prevalence of the symptoms of reflux (hearthburn and acid regurgitation) and of gastro-esophageal reflux disease is high. Numerous lifestyle modifications have been advocated in the prognosis of reflux. Obesity, the decubitus, eating rapidly, tobacco, alcohol and exercise provoke symptoms of the reflux (hearthburn and acid regurgitation). The proportion of fat in the food and stress aren't factors associated with reflux. Some works point at the chocolate, at the acid juices, at the carbonated beverages and at the onions as factors that unleash symptoms of reflux. Nevertheless larger prospective controlled trials are warranted. Gum-chewing after eating, keep standing up and to go to bed 4 h after dinner improves the symptoms of the reflux and the gastro-esophageal reflux disease.
