While eating your meals, limit your beverage consumption. Although this may sound silly, drinking lots of beverages during your meals can actually cause acid reflux. This is because liquids increase the volume of food in your stomach. When your stomach is full, the lower esophageal sphincter has more pressure placed upon it. This muscle prevents food from coming up through your esophagus, which prevents acid reflux. You need to protect your lower esophageal sphincter as much as possible.
