Does coffee cause indigestion?

Some people believe that coffee causes acid reflux or GERD. While coffee and caffeine may trigger symptoms, researchers have not conclusively shown a link between coffee and GERD. Does coffee cause indigestion?

@atharva Coffee and indigestion may go hand-in-hand for some individuals. Coffee contains caffeine and other compounds that cause your stomach to produce more acid and may irritate its lining. In addition to indigestion, you may also experience heartburn, or acid reflux. This occurs when the contents of your stomach come up into the esophagus. If the acid reflux is chronic, this is a condition called gastroesophageal reflux disease, or GERD, notes the National Institute of Diabetes and Digestive and Kidney Diseases.
