“Dietary and lifestyle changes are the first step in treating GERD. Certain foods make the reflux worse. Suggestions to help alleviate symptoms include:

• Lose weight if you are overweight — of all of the lifestyle changes you can make, this one is the most effective.
• Avoid foods that increase the level of acid in your stomach, including caffeinated beverages.
• Avoid foods that decrease the pressure in the lower esophagus, such as fatty foods, alcohol and peppermint.”
