GERD
GERD/PUD? symptoms such as heartburn or regurgitation may often be exacerbated by alcohol and certain foods, including those containing caffeine, garlic, and peppermint, as well as fatty foods. These foods and alcohol often cause relaxation of the lower esophageal sphincter, allowing the refluxate to enter into the esophagus from the stomach, thus causing heartburn or regurgitation.
