Can coffee cause indigestion?

“Caffeine does increase the acidity of gastric secretions”, but doesn't appear to cause digestive issues for most people.

Drinking coffee is beneficial for gut health and improves bowel movement by increasing the motility of smooth muscle in the gastrointestinal tract.

Caffeine relaxes the lower esophageal sphincter which is a muscular tube that connects your mouth and your stomach in the upper and lower portions contract and relaxes to allow food and liquid to pass.

To decrease the acidity of such secretions, vegetables can be a remedy to reduce stomach acids as they are naturally low in fat and sugar.

But, if acid is an issue and coffee is your morning fix, you can still enjoy your morning fix:

Coffees that are grown at low altitudes typically have lower acid levels and they are stomach-friendly coffee beans.

A dark roast coffee has fewer of the compounds that increase stomach acid and a greater chance of a coffee that doesn’t cause symptoms and is easier on the stomach. 

Cold brewing coffee in cold water reduces the acid levels of the drink by as much as 66%. and add hot water to enjoy a hot mug like normal.

Drinking coffee on an empty stomach is perfectly fine.
