Gastroesophageal reflux disease (GERD) should be treated with moderate to small amounts of water as needed. GERD is caused by the reflux of gastroduodenal contents into the esophagus and can lead to reflux esophagitis as well as damage to tissues outside the esophagus, such as the throat and airway. General treatment for GERD includes lifestyle and dietary changes. The former includes avoiding eating within 2 hours before bedtime and elevating the head of the bed appropriately, etc. The latter mainly refers to avoiding foods that lower the pressure on the lower esophageal sphincter, such as high fat, chocolate, and strong tea. Generally speaking, drinking water will lead to an increase in intragastric pressure, so GERD patients need to drink less water at the right time and in the right amount as needed. Gastroesophageal reflux disease should be standardized treatment under the guidance of physicians, do not change the treatment arbitrarily, and go to the hospital in case of any discomfort in order to avoid delaying the condition.
