Consultant gastroenterohepatology, Prof. Ari Fahrial Syam, does not confirm that Americano is the only type of coffee brew that is safe for GERD patients. Because the principle of whether coffee is safe or unsafe depends on the caffeine content. According to Prof. Ari, GERD sufferers will be safer consuming coffee with low caffeine content. Coffee can increase stomach acid in GERD sufferers because of its high caffeine levels.
