Gastroenterologists say most healthy adults can drink coffee without eating first, though caffeine and coffee’s effects on digestion may cause symptoms for some people. The two reports describe similar evidence and advice.

Gastroenterologist Asma Khapra said studies have not shown that coffee on an empty stomach causes major cortisol, blood-sugar, or metabolic problems.
Coffee can stimulate stomach acid release, and caffeine may contribute to heartburn, increased heart rate or blood pressure, anxiety, and sleep problems.
The reports say caffeine is absorbed more rapidly on an empty stomach, while individual responses vary; Khapra said drinking coffee that way is fine if it is enjoyed without large amounts of additions.
