It is advisable to spit out the water from the stomach. Gastroesophageal reflux (GERD) is considered to be the cause of gastroesophageal reflux (GERD). The water in the stomach reflux water is actually stomach acid, which needs to pass through the esophagus in the process of reflux water, and the acidic liquid and high concentration of stomach acid will have great damage to the esophageal mucosa, and swallowing it will cause secondary damage to the esophagus. In order to prevent this, it is recommended to spit out the water directly in the process of gastric reflux, which can dilute the gastric acid and reduce its damage to the esophagus. If you have frequent gastric reflux, you need to pay attention to timely change of living and eating habits, you can eat less and more meals. At the same time, avoid drinking coffee, strong tea, etc., do not lie down immediately after a full meal. If necessary, you need to use acid-suppressing agents and gastrointestinal mucosal protectants under the guidance of a doctor. Because frequent acid reflux will cause great damage to the esophagus and increase the risk of esophageal cancer, so when acid reflux occurs in the first place, it is necessary to consult a doctor in time and follow the doctor’s instructions to carry out standardized and timely diagnosis and treatment.
