Does Diet Coke and mentos cause acid reflux?

The combination of Diet Coke and Mentos does not typically cause acid reflux. Acid reflux occurs when the contents of the stomach flow back into the oesophagus, the tube that connects the mouth to the stomach. Acid reflux is sometimes referred to as heartburn.

While the combination of Diet Coke and Mentos does not necessarily cause acid reflux, consuming Diet Coke or Mentos individually may contribute to acid reflux for some people.
